The API layer (factories/builders) creates domain events and tags. +2. Events serialize through base encoders/decoders into canonical NIP-01 JSON. +3.

Facade Pattern + +**Where:** NIP implementation classes (NIP01, NIP57, etc.) + +**Purpose:** Provide a simplified interface to complex subsystems. + +**Example:** +```java +// NIP01 facade coordinates builders, factories, and event management +NIP01 nip01 = new NIP01(identity); +nip01.createTextNoteEvent("Hello World") + .sign() + .send(relayUri); + +// Internally delegates to: +// - NIP01EventBuilder for event construction +// - NIP01TagFactory for tag creation +// - NIP01MessageFactory for message formatting +// - Event signing and serialization subsystems +``` + +**Benefits:** +- Simplified API for common use cases +- Hides complexity of event construction +- Clear separation of concerns + +### 2. Builder Pattern + +**Where:** Event construction, complex parameter objects + +**Purpose:** Construct complex objects step-by-step with readable code. + +**Examples:** +```java +// GenericEvent builder +GenericEvent event = GenericEvent.builder() + .pubKey(publicKey) + .kind(Kind.TEXT_NOTE) + .content("Hello Nostr!") + .tags(List.of(eventTag, pubKeyTag)) + .build(); + +// ZapRequestParameters (Parameter Object pattern) +ZapRequestParameters params = ZapRequestParameters.builder() + .amount(1000L) + .lnUrl("lnurl...") + .relays(relayList) + .content("Great post!") + .recipientPubKey(recipient) + .build(); + +nip57.createZapRequestEvent(params); +``` + +**Benefits:** +- Readable event construction +- Handles optional parameters elegantly +- Replaces methods with many parameters + +### 3. Template Method Pattern + +**Where:** GenericEvent validation + +**Purpose:** Define algorithm skeleton in base class, allow subclasses to override specific steps. + +**Example:** +```java +// GenericEvent.java +public void validate() { + // Validate base fields (cannot be overridden) + EventValidator.validateId(this.id); + EventValidator.validatePubKey(this.pubKey); + EventValidator.validateSignature(this.signature); + EventValidator.validateCreatedAt(this.createdAt); + + // Call protected methods (CAN be overridden by subclasses) + validateKind(); + validateTags(); + validateContent(); +} + +protected void validateTags() { + EventValidator.validateTags(this.tags); +} + +// ZapRequestEvent.java (subclass) +@Override +protected void validateTags() { + super.validateTags(); // Base validation + // Additional validation: require 'amount' tag + requireTag("amount"); + requireTag("relays"); +} +``` + +**Benefits:** +- Reuses common validation logic +- Allows specialization in subclasses +- Maintains consistency across event types + +### 4. Value Object Pattern + +**Where:** RelayUri, SubscriptionId, PublicKey, PrivateKey + +**Purpose:** Immutable objects representing domain concepts with no identity, only value. + +**Examples:** +```java +// RelayUri - validates WebSocket URIs +RelayUri relay = new RelayUri("wss://relay.398ja.xyz"); +// Throws IllegalArgumentException if not ws:// or wss:// + +// SubscriptionId - type-safe subscription identifiers +SubscriptionId subId = SubscriptionId.of("my-subscription"); +// Throws IllegalArgumentException if blank + +// Equality based on value, not object identity +RelayUri r1 = new RelayUri("wss://relay.398ja.xyz"); +RelayUri r2 = new RelayUri("wss://relay.398ja.xyz"); +assert r1.equals(r2); // true - same value +``` + +**Benefits:** +- Compile-time type safety (can't mix up String parameters) +- Encapsulates validation logic +- Immutable (thread-safe) +- Self-documenting code + +### 5. Factory Pattern + +**Where:** NIP01TagFactory, NIP57TagFactory, Event factories + +**Purpose:** Encapsulate object creation logic. + +**Examples:** +```java +// NIP01TagFactory - creates NIP-01 standard tags +BaseTag eventTag = tagFactory.createEventTag(eventId, recommendedRelay); +BaseTag pubKeyTag = tagFactory.createPubKeyTag(publicKey, mainRelay); +BaseTag genericTag = tagFactory.createGenericTag("t", "nostr"); + +// NIP01EventBuilder - creates events with proper defaults +GenericEvent textNote = eventBuilder.buildTextNote("Hello!"); +GenericEvent metadata = eventBuilder.buildMetadata(userMetadata); +``` + +**Benefits:** +- Centralizes creation logic +- Ensures proper initialization +- Makes testing easier (mock factories) + +### 6. Utility Pattern + +**Where:** EventValidator, EventSerializer, EventTypeChecker, EventJsonMapper + +**Purpose:** Provide static helper methods for common operations. + +**Examples:** +```java +// EventValidator - validates NIP-01 fields +EventValidator.validateId(eventId); +EventValidator.validatePubKey(publicKey); +EventValidator.validateSignature(signature); + +// EventSerializer - canonical NIP-01 serialization +String json = EventSerializer.serialize(pubKey, createdAt, kind, tags, content); +String eventId = EventSerializer.serializeAndComputeId(...); + +// EventTypeChecker - classifies event kinds +boolean isReplaceable = EventTypeChecker.isReplaceable(kind); // 10000-19999 +boolean isEphemeral = EventTypeChecker.isEphemeral(kind); // 20000-29999 +boolean isAddressable = EventTypeChecker.isAddressable(kind); // 30000-39999 + +// EventJsonMapper - centralized JSON configuration +ObjectMapper mapper = EventJsonMapper.getMapper(); +String json = mapper.writeValueAsString(event); +``` + +**Benefits:** +- No object instantiation needed +- Clear single purpose +- Easy to test +- Reusable across the codebase + +### 7. Delegation Pattern + +**Where:** GenericEvent → Validators/Serializers/TypeCheckers + +**Purpose:** Delegate responsibilities to specialized classes. + +**Example:** +```java +// GenericEvent delegates instead of implementing directly +public class GenericEvent extends BaseEvent { + + public void update() { + // Delegates to EventSerializer + this._serializedEvent = EventSerializer.serializeToBytes(...); + this.id = EventSerializer.computeEventId(this._serializedEvent); + } + + public void validate() { + // Delegates to EventValidator + EventValidator.validateId(this.id); + EventValidator.validatePubKey(this.pubKey); + // ... + } + + public boolean isReplaceable() { + // Delegates to EventTypeChecker + return EventTypeChecker.isReplaceable(this.kind); + } +} +``` + +**Benefits:** +- Single Responsibility Principle +- Testable independently +- Reusable logic + +### 8. Initialization-on-Demand Holder (Singleton) + +**Where:** NostrSpringWebSocketClient + +**Purpose:** Thread-safe lazy singleton initialization. + +**Example:** +```java +public class NostrSpringWebSocketClient { + + private static final class InstanceHolder { + private static final NostrSpringWebSocketClient INSTANCE = + new NostrSpringWebSocketClient(); + + private InstanceHolder() {} + } + + public static NostrIF getInstance() { + return InstanceHolder.INSTANCE; + } +} +``` + +**Benefits:** +- Thread-safe without synchronization overhead +- Lazy initialization (created on first access) +- JVM guarantees initialization safety + +--- + +## Refactored Components (2025) + +Recent refactoring efforts (v0.6.2) have significantly improved code organization by extracting god classes into focused, single-responsibility components. + +### GenericEvent Extraction + +**Before:** 367 lines with mixed responsibilities +**After:** 374 lines + 3 extracted utility classes (472 additional lines) + +**Extracted Classes:** + +1. **EventValidator** (158 lines) → `nostr.event.validator.EventValidator` + -

NIP-01 defines the core protocol for creating, signing, and transmitting events over + * Nostr relays. This class provides a high-level API for working with basic event types, + * tags, and messages without needing to understand the underlying implementation details. + * + *

What is NIP-01? + *

    + *
  • Event Structure: Defines the JSON format for events (id, pubkey, created_at, + * kind, tags, content, sig)
    • + *
  • Event Kinds: Basic kinds like text notes (1), metadata (0), contacts (3)
    • + *
  • Event Types: Regular, replaceable, ephemeral, and addressable events
    • + *
  • Tags: Standard tags like 'e' (event reference), 'p' (public key), 'd' (identifier)
    • + *
  • Messages: Client-relay communication (EVENT, REQ, CLOSE, EOSE, NOTICE)
    • + *
+ * + *

Design Pattern: This class uses the Facade Pattern to hide the complexity of: + *

    + *
  • {@link NIP01EventBuilder} - Event construction logic
    • + *
  • {@link NIP01TagFactory} - Tag creation logic
    • + *
  • {@link NIP01MessageFactory} - Message formatting logic
    • + *
+ * + *

Usage Example: + * 

{@code
+ * // Create NIP01 instance with sender identity
+ * Identity identity = new Identity(privateKey);
+ * NIP01 nip01 = new NIP01(identity);
+ *
+ * // Create and send a simple text note
+ * nip01.createTextNoteEvent("Hello Nostr!")
+ *      .sign()
+ *      .send(relayUri);
+ *
+ * // Create a text note with tags
+ * List tags = List.of(
+ *     NIP01.createEventTag("event_id_hex", Marker.REPLY),
+ *     NIP01.createPubKeyTag(recipientPublicKey)
+ * );
+ * nip01.createTextNoteEvent(tags, "Hello @recipient!")
+ *      .sign()
+ *      .send(relayUri);
+ *
+ * // Create metadata event
+ * UserProfile profile = UserProfile.builder()
+ *     .name("Alice")
+ *     .about("Nostr enthusiast")
+ *     .picture("https://example.com/avatar.jpg")
+ *     .build();
+ * nip01.createMetadataEvent(profile)
+ *      .sign()
+ *      .send(relayUri);
+ *
+ * // Create static tags and messages (without sender)
+ * BaseTag eventTag = NIP01.createEventTag("event_id");
+ * BaseTag pubKeyTag = NIP01.createPubKeyTag(publicKey);
+ * ReqMessage reqMsg = NIP01.createReqMessage("sub_id", List.of(filters));
+ * }
+ * + *

Event Types Supported: + *

    + *
  • Text Notes: {@link #createTextNoteEvent(String)} - Basic short-form content (kind 1)
    • + *
  • Metadata: {@link #createMetadataEvent(UserProfile)} - User profile data (kind 0)
    • + *
  • Replaceable: {@link #createReplaceableEvent(Integer, String)} - Latest replaces earlier
    • + *
  • Ephemeral: {@link #createEphemeralEvent(Integer, String)} - Not stored by relays
    • + *
  • Addressable: {@link #createAddressableEvent(Integer, String)} - Replaceable with identifier
    • + *
+ * + *

Tag Types Supported: + *

    + *
  • Event tags (e): {@link #createEventTag(String)} - References to other events
    • + *
  • Public key tags (p): {@link #createPubKeyTag(PublicKey)} - References to users
    • + *
  • Identifier tags (d): {@link #createIdentifierTag(String)} - For addressable events
    • + *
  • Address tags (a): {@link #createAddressTag(Integer, PublicKey, String)} - Addressable event refs
    • + *
+ * + *

Message Types Supported: + *

    + *
  • EVENT: {@link #createEventMessage(GenericEvent, String)} - Publish events
    • + *
  • REQ: {@link #createReqMessage(String, List)} - Subscribe to events
    • + *
  • CLOSE: {@link #createCloseMessage(String)} - Unsubscribe
    • + *
  • EOSE: {@link #createEoseMessage(String)} - End of stored events
    • + *
  • NOTICE: {@link #createNoticeMessage(String)} - Human-readable messages
    • + *
+ * + *

Method Chaining: This class supports fluent API style: + * 

{@code
+ * nip01.createTextNoteEvent("Hello World")  // Create event
+ *      .sign()                               // Sign with sender's private key
+ *      .send(relayUri)                       // Send to relay
+ *      .get();                               // Get response
+ * }
+ * + *

Sender Management: The sender identity can be set at construction or changed later: + * 

{@code
+ * NIP01 nip01 = new NIP01(identity);  // Set sender at construction
+ * nip01.setSender(newIdentity);        // Change sender later
+ * }
+ * + *

Migration Note: Version 0.6.2 deprecated methods that accept Identity parameters + * in favor of using the configured sender. Those overloads have been removed in 1.0.0. + * + *

Build and encrypt DM events. - * Spec: https://github.com/nostr-protocol/nips/blob/master/04.md + * NIP-04: Encrypted Direct Messages. + * + *

This class provides utilities for creating, encrypting, and decrypting private direct messages + * (DMs) on the Nostr protocol. NIP-04 uses AES-256-CBC encryption with a shared secret derived from + * ECDH (Elliptic Curve Diffie-Hellman) key agreement. + * + *

What is NIP-04?

+ * + *

NIP-04 defines encrypted direct messages as kind-4 events where: + *

    + *
  • The content is encrypted using AES-256-CBC
    • + *
  • The encryption key is derived from ECDH between sender and recipient
    • + *
  • A 'p' tag indicates the recipient's public key
    • + *
  • The encrypted content format is: base64(ciphertext)?iv=base64(initialization_vector)
    • + *
+ * + *

Security Note

+ * + *

NIP-04 is deprecated for new applications. Use NIP-44 instead, which provides: + *

    + *
  • Better encryption scheme (XChaCha20-Poly1305)
    • + *
  • Authenticated encryption (AEAD)
    • + *
  • Protection against padding oracle attacks
    • + *
  • No metadata leakage through message length
    • + *
+ * + *

NIP-04 is maintained for backward compatibility with existing clients and messages. + * + *

Usage Examples

+ * + *

Example 1: Send an Encrypted DM

+ * 
{@code
+ * Identity sender = new Identity("nsec1...");
+ * PublicKey recipient = new PublicKey("npub1...");
+ *
+ * NIP04 nip04 = new NIP04(sender, recipient);
+ * nip04.createDirectMessageEvent("Hello! This is a private message.")
+ *      .sign()
+ *      .send(relays);
+ * }
+ * + *

Example 2: Decrypt a Received DM (as recipient)

+ * 
{@code
+ * Identity myIdentity = new Identity("nsec1...");
+ * GenericEvent dmEvent = ... // received from relay (kind 4)
+ *
+ * String plaintext = NIP04.decrypt(myIdentity, dmEvent);
+ * System.out.println("Received: " + plaintext);
+ * }
+ * + *

Example 3: Decrypt Your Own Sent DM

+ * 
{@code
+ * Identity myIdentity = new Identity("nsec1...");
+ * GenericEvent myDmEvent = ... // a DM I sent (kind 4)
+ *
+ * // Works for both sender and recipient
+ * String plaintext = NIP04.decrypt(myIdentity, myDmEvent);
+ * System.out.println("I sent: " + plaintext);
+ * }
+ * + *

Example 4: Standalone Encrypt/Decrypt

+ * 
{@code
+ * Identity sender = new Identity("nsec1...");
+ * PublicKey recipient = new PublicKey("npub1...");
+ *
+ * // Encrypt a message
+ * String encrypted = NIP04.encrypt(sender, "Secret message", recipient);
+ *
+ * // Decrypt it (either party can decrypt with their private key + other's public key)
+ * String decrypted = NIP04.decrypt(sender, encrypted, recipient);
+ * }
+ * + *

Design Pattern

+ * + *

This class follows the Facade Pattern, providing a simplified interface for: + *

    + *
  • Event creation (delegates to {@code GenericEventFactory})
    • + *
  • Encryption (delegates to {@code MessageCipher04})
    • + *
  • Decryption (delegates to {@code MessageCipher04})
    • + *
  • Event signing and sending (inherited from {@code EventNostr})
    • + *
+ * + *

How Encryption Works

+ * + *
    + *
  1. Key Agreement: ECDH produces a shared secret from sender's private key + recipient's public key
    2. + *
  2. IV Generation: A random 16-byte initialization vector is generated
    3. + *
  3. Encryption: AES-256-CBC encrypts the plaintext message
    4. + *
  4. Format: Output is base64(ciphertext)?iv=base64(iv)
    5. + *
+ * + *

Known Limitations

+ * + *
    + *
  • No authentication: Vulnerable to tampering (use NIP-44 for AEAD)
    • + *
  • Padding oracle risk: CBC mode can leak info through padding errors
    • + *
  • Metadata leakage: Message length is visible (NIP-44 pads to fixed sizes)
    • + *
  • Replay attacks: No nonce/counter mechanism
    • + *
+ * + *

Thread Safety

What is NIP-44?

+ * + *

NIP-44 is the successor to NIP-04 and provides: + *

    + *
  • XChaCha20-Poly1305 AEAD: Authenticated encryption prevents tampering
    • + *
  • Padding: Messages are padded to standard sizes to hide true length
    • + *
  • Versioning: Version byte (0x02) allows future algorithm upgrades
    • + *
  • HMAC-SHA256 for key derivation: Safer than raw ECDH
    • + *
  • Protection against metadata leakage: Padding obscures message size
    • + *
+ * + *

When to Use NIP-44

+ * + *

Use NIP-44 for: + *

    + *
  • New applications: Always prefer NIP-44 over NIP-04
    • + *
  • Private DMs: Kind 4 events with encrypted content
    • + *
  • Encrypted content fields: Any event that needs encrypted data
    • + *
  • Group messaging: When combined with multi-recipient protocols
    • + *
+ * + *

Use NIP-04 only for: + *

    + *
  • Backward compatibility with legacy clients
    • + *
  • Reading existing NIP-04 encrypted messages
    • + *
+ * + *

Usage Examples

+ * + *

Example 1: Encrypt a Message

+ * 
{@code
+ * Identity alice = new Identity("nsec1...");
+ * PublicKey bob = new PublicKey("npub1...");
+ *
+ * String encrypted = NIP44.encrypt(alice, "Hello Bob!", bob);
+ * // Returns a versioned encrypted payload (starts with 0x02)
+ * }
+ * + *

Example 2: Decrypt a Message

+ * 
{@code
+ * Identity bob = new Identity("nsec1...");
+ * PublicKey alice = new PublicKey("npub1...");
+ * String encrypted = "..."; // received encrypted message
+ *
+ * String plaintext = NIP44.decrypt(bob, encrypted, alice);
+ * System.out.println(plaintext); // "Hello Bob!"
+ * }
+ * + *

Example 3: Decrypt an Encrypted DM Event (Kind 4)

+ * 
{@code
+ * Identity myIdentity = new Identity("nsec1...");
+ * GenericEvent dmEvent = ... // received kind-4 event with NIP-44 encryption
+ *
+ * String plaintext = NIP44.decrypt(myIdentity, dmEvent);
+ * // Works whether you're the sender or recipient
+ * }
+ * + *

Example 4: Create and Send an Encrypted DM (Manual)

+ * 
{@code
+ * Identity sender = new Identity("nsec1...");
+ * PublicKey recipient = new PublicKey("npub1...");
+ *
+ * // Encrypt the message

Encryption Format

+ * + *

NIP-44 ciphertext structure (base64-encoded): + * 

+ * [version (1 byte)][nonce (32 bytes)][ciphertext (variable)][MAC (16 bytes)]
+ *
+ * + *
    + *
  • Version: 0x02 (current version)
    • + *
  • Nonce: 32-byte random value (XChaCha20 nonce)
    • + *
  • Ciphertext: Encrypted + padded message
    • + *
  • MAC: 16-byte Poly1305 authentication tag
    • + *
+ * + *

Padding Scheme

+ * + *

Messages are padded to the next power-of-2 size (up to 64KB), hiding the true message length: + *

    + *
  • 0-32 bytes → padded to 32 bytes
    • + *
  • 33-64 bytes → padded to 64 bytes
    • + *
  • 65-128 bytes → padded to 128 bytes
    • + *
  • ... and so on up to 65536 bytes
    • + *
+ * + *

Security Properties

+ * + *
    + *
  • Confidentiality: XChaCha20 encryption
    • + *
  • Authenticity: Poly1305 MAC prevents tampering
    • + *
  • Forward secrecy: No (static key pairs)
    • + *
  • Metadata protection: Padding hides message length
    • + *
  • Replay protection: No (application-level responsibility)
    • + *
+ * + *

Thread Safety

All static methods in this class are thread-safe. + * + *

Design Pattern

Build zap request/receipt events and related tags. - * Spec: https://github.com/nostr-protocol/nips/blob/master/57.md + * NIP-57: Lightning Zaps. + * + *

This class provides utilities for creating and managing Lightning Network zaps on Nostr. Zaps + * are a standardized way to send Bitcoin payments (via Lightning Network) to Nostr users, content, + * or events, with the payment being publicly recorded on Nostr relays. + * + *

What are Zaps?

+ * + *

Zaps enable Bitcoin micropayments on Nostr: + *

    + *
  • Zap Request (kind 9734): A request to send sats to a user or event
    • + *
  • Zap Receipt (kind 9735): Public proof that a payment was completed
    • + *
  • Lightning Integration: Uses LNURL and Lightning invoices (bolt11)
    • + *
  • Public Attribution: Zaps are publicly visible on relays (unlike tips)
    • + *
+ * + *

How Zaps Work

+ * + *
    + *
  1. User creates a zap request (kind 9734) specifying amount and recipient
    2. + *
  2. Request is sent to an LNURL server (specified in recipient's NIP-05 profile)
    3. + *
  3. LNURL server returns a Lightning invoice (bolt11)
    4. + *
  4. User pays the invoice via their Lightning wallet
    5. + *
  5. LNURL server publishes a zap receipt (kind 9735) to Nostr relays
    6. + *
  6. Receipt is visible to everyone as proof of payment
    7. + *
+ * + *

Zap Types

+ * + *
    + *
  • Public Zaps: Sender is visible (default)
    • + *
  • Private Zaps: Sender is anonymous (requires NIP-04 encryption)
    • + *
  • Profile Zaps: Zap a user's profile
    • + *
  • Event Zaps: Zap a specific note or event
    • + *
  • Anonymous Zaps: No sender attribution
    • + *
+ * + *

Usage Examples

+ * + *

Example 1: Create a Zap Request (Profile Zap)

+ * 
{@code
+ * Identity sender = new Identity("nsec1...");
+ * PublicKey recipient = new PublicKey("npub1...");
+ *
+ * NIP57 nip57 = new NIP57(sender);
+ * nip57.createZapRequestEvent(
+ *         1000L,                              // amount in millisatoshis
+ *         "lnurl1...",                        // LNURL from recipient's profile
+ *         List.of("wss://relay.damus.io"),   // relays to publish receipt
+ *         "Great content! ⚡",                // optional comment
+ *         recipient                           // recipient public key
+ *     )
+ *     .sign()
+ *     .send(relays); // sends to LNURL server (not relays)
+ * }
+ * + *

Example 2: Create a Zap Request (Event Zap)

+ * 
{@code
+ * Identity sender = new Identity("nsec1...");
+ * GenericEvent noteToZap = ... // the note you want to zap
+ * PublicKey author = noteToZap.getPubKey();
+ *
+ * NIP57 nip57 = new NIP57(sender);
+ * nip57.createZapRequestEvent(
+ *         5000L,                              // 5000 millisats
+ *         "lnurl1...",                        // author's LNURL
+ *         List.of("wss://relay.damus.io"),
+ *         "Amazing post! 🔥",
+ *         author,
+ *         noteToZap,                          // the event being zapped
+ *         null                                // no address tag (for kind 1 events)
+ *     )
+ *     .sign()
+ *     .send(relays);
+ * }
+ * + *

Example 3: Create a Zap Request with Parameter Object

+ * 
{@code
+ * Identity sender = new Identity("nsec1...");
+ * PublicKey recipient = new PublicKey("npub1...");
+ *
+ * ZapRequestParameters params = ZapRequestParameters.builder()
+ *     .amount(1000L)
+ *     .lnUrl("lnurl1...")
+ *     .relays(List.of(new Relay("wss://relay.damus.io")))
+ *     .content("Thanks for the content!")
+ *     .recipientPubKey(recipient)
+ *     .build();
+ *
+ * NIP57 nip57 = new NIP57(sender);
+ * nip57.createZapRequestEvent(params)
+ *     .sign()
+ *     .send(relays);
+ * }
+ * + *

Example 4: Create a Zap Receipt (LNURL server use case)

+ * 
{@code
+ * // This is typically done by the LNURL server after payment is confirmed
+ * Identity lnurlServer = new Identity("nsec_of_lnurl_server...");
+ * GenericEvent zapRequest = ... // the original zap request
+ * String bolt11 = "lnbc..."; // the paid Lightning invoice
+ * String preimage = "..."; // payment preimage (proof of payment)
+ * PublicKey recipient = zapRequest.getPubKey();
+ *
+ * NIP57 nip57 = new NIP57(lnurlServer);
+ * nip57.createZapReceiptEvent(zapRequest, bolt11, preimage, recipient)
+ *     .sign()
+ *     .send(relays); // publishes receipt to Nostr
+ * }
+ * + *

Design Pattern

+ * + *

This class follows the Facade Pattern combined with Builder Pattern: + *

    + *
  • Facade: Simplifies zap request/receipt creation
    • + *
  • Builder: {@link NIP57ZapRequestBuilder} and {@link NIP57ZapReceiptBuilder} handle construction
    • + *
  • Parameter Object: {@link ZapRequestParameters} groups related parameters
    • + *
  • Method Chaining: Fluent API for sign() and send()
    • + *
+ * + *

Key Concepts

+ * + *

Amount (millisatoshis)

+ *

Amounts are specified in millisatoshis (msat = 1/1000 of a satoshi = 1/100,000,000,000 BTC). + *

    + *
  • 1 satoshi = 1,000 millisatoshis
    • + *
  • Example: 1000 msat = 1 sat ≈ $0.0006 USD (at $60k BTC)
    • + *
+ * + *

LNURL

+ *

Lightning URL (LNURL) is a protocol for Lightning payments. The recipient's LNURL is typically + * found in their NIP-05 profile metadata. The LNURL server generates invoices and publishes receipts. + * + *

Bolt11

+ *

Bolt11 is the Lightning invoice format. It's a bech32-encoded payment request that includes: + *

    + *
  • Payment amount
    • + *
  • Payment hash
    • + *
  • Expiration time
    • + *
  • Routing hints
    • + *
+ * + *

Event Tags

+ * + *

Zap requests (kind 9734) include: + *

    + *
  • relays tag: Where the zap receipt should be published
    • + *

Build wallet, token, spending history and quote events. - * Spec: https://github.com/nostr-protocol/nips/blob/master/60.md + * NIP-60: Cashu Wallet over Nostr. + * + *

This class provides utilities for managing Cashu wallets on Nostr. Cashu is an ecash system + * for Bitcoin that enables private, custodial Bitcoin wallets. NIP-60 defines how to store and + * manage Cashu tokens, wallet metadata, transaction history, and quotes on Nostr relays. + * + *

What is Cashu?

+ * + *

Cashu is a Chaumian ecash system for Bitcoin: + *

    + *
  • Ecash tokens: Bearer instruments backed by Bitcoin (like digital cash)
    • + *
  • Blind signatures: Mint can't link tokens to users (privacy)
    • + *
  • Custodial: Tokens are backed by Bitcoin held by the mint
    • + *
  • Transferable: Tokens can be sent peer-to-peer offline
    • + *
  • Lightweight: No blockchain, instant transactions
    • + *
+ * + *

What is NIP-60?

+ * + *

NIP-60 defines how to store Cashu wallet data on Nostr: + *

    + *
  • Wallet events (kind 37375): Wallet configuration and mint URLs
    • + *
  • Token events (kind 7375): Unspent Cashu tokens (proofs)
    • + *
  • History events (kind 7376): Transaction history
    • + *
  • Quote events (kind 7377): Reserved tokens for redemption
    • + *
+ * + *

Benefits of storing Cashu on Nostr: + *

    + *
  • Backup: Tokens are backed up to relays (recover lost wallet)
    • + *
  • Sync: Multiple devices can access the same wallet
    • + *
  • Privacy: Events can be encrypted with NIP-04 or NIP-44
    • + *
  • Portable: Move wallets between clients
    • + *
+ * + *

Event Kinds

+ * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + *
KindNameDescription
37375Wallet EventWallet metadata: name, mints, relays, supported units
7375Token EventUnspent Cashu tokens (proofs) linked to a wallet
7376History EventTransaction history: send, receive, swap
7377Quote EventReserved tokens for Lightning redemption
+ * + *

Usage Examples

+ * + *

Example 1: Create a Wallet Event

+ * 
{@code
+ * Identity walletOwner = new Identity("nsec1...");
+ *
+ * CashuWallet wallet = CashuWallet.builder()
+ *     .name("My Cashu Wallet")
+ *     .mints(List.of(
+ *         new CashuMint("https://mint.minibits.cash/Bitcoin", List.of("sat", "msat"))
+ *     ))
+ *     .relays(List.of(new Relay("wss://relay.damus.io")))
+ *     .unit("sat")
+ *     .build();
+ *
+ * NIP60 nip60 = new NIP60(walletOwner);
+ * nip60.createWalletEvent(wallet)
+ *      .sign()
+ *      .send(relays);
+ * }
+ * + *

Example 2: Create a Token Event (Store Unspent Tokens)

+ * 
{@code
+ * Identity walletOwner = new Identity("nsec1...");
+ * CashuWallet wallet = ... // existing wallet
+ *
+ * CashuToken token = CashuToken.builder()
+ *     .mint("https://mint.minibits.cash/Bitcoin")
+ *     .proofs(List.of(...)) // list of proofs from the mint
+ *     .build();
+ *
+ * NIP60 nip60 = new NIP60(walletOwner);
+ * nip60.createTokenEvent(token, wallet)
+ *      .sign()
+ *      .send(relays); // backup tokens to relays
+ * }
+ * + *

Example 3: Create a Spending History Event

+ * 
{@code
+ * Identity walletOwner = new Identity("nsec1...");
+ * CashuWallet wallet = ... // existing wallet
+ *
+ * SpendingHistory history = SpendingHistory.builder()
+ *     .direction("out") // "in" or "out"
+ *     .amount(new Amount(1000, "sat"))
+ *     .timestamp(System.currentTimeMillis() / 1000)
+ *     .description("Paid for coffee")
+ *     .build();
+ *
+ * NIP60 nip60 = new NIP60(walletOwner);
+ * nip60.createSpendingHistoryEvent(history, wallet)
+ *      .sign()
+ *      .send(relays);
+ * }
+ * + *

Example 4: Create a Redemption Quote Event

+ * 
{@code
+ * Identity walletOwner = new Identity("nsec1...");
+ *
+ * CashuQuote quote = CashuQuote.builder()
+ *     .quoteId("quote_abc123")
+ *     .amount(new Amount(5000, "sat"))
+ *     .mint("https://mint.minibits.cash/Bitcoin")
+ *     .request("lnbc5000n...") // Lightning invoice
+ *     .state("pending") // pending, paid, unpaid
+ *     .build();
+ *
+ * NIP60 nip60 = new NIP60(walletOwner);
+ * nip60.createRedemptionQuoteEvent(quote)
+ *      .sign()
+ *      .send(relays);
+ * }
+ * + *

Key Concepts

+ * + *

Cashu Proofs

+ *

Cashu proofs are the actual tokens. They are JSON objects containing: + *

    + *
  • id: Keyset ID (identifies the mint's keys)
    • + *
  • amount: Token denomination (e.g., 1, 2, 4, 8, 16... sats)
    • + *
  • secret: Random secret (proves ownership)
    • + *
  • C: Blinded signature from the mint
    • + *
+ * + *

Mints

+ *

Mints are custodians that issue Cashu tokens. Each mint: + *

    + *
  • Holds Bitcoin reserves backing the tokens
    • + *
  • Signs tokens with blind signatures
    • + *
  • Redeems tokens for Bitcoin (Lightning)
    • + *
  • Can support multiple units (sat, msat, USD, EUR, etc.)
    • + *
+ * + *

Wallet Tags

+ *

Wallet events use a 'd' tag to identify the wallet (like an address). Token, history, and + * quote events reference this 'd' tag to associate data with a specific wallet. + * + *

Security Considerations

+ * + *
    + *
  • Encrypt events: Use NIP-04 or NIP-44 to encrypt token events (proofs are bearer instruments!)
    • + *
  • Relay trust: Relays can see encrypted data but not decrypt it
    • + *
  • Mint trust: Mints are custodial - they hold your Bitcoin
    • + *
  • Backup regularly: Sync tokens to relays to prevent loss
    • + *
  • Spent tokens: Delete spent token events to avoid confusion
    • + *
+ * + *

Design Pattern

+ * + *

This class follows the Facade Pattern: + *

    + *
  • Simplifies creation of NIP-60 events (wallet, token, history, quote)
    • + *
  • Delegates to {@link GenericEventFactory} for event construction
    • + *
  • Uses entity classes ({@link CashuWallet}, {@link CashuToken}, {@link SpendingHistory}, {@link CashuQuote})
    • + *
  • Provides static helper methods for tag creation
    • + *
+ * + *

Thread Safety

  • Is case-insensitive (always lowercase by convention)
    • + *
  • Uses separator '1' between HRP and data
    • + *
+ * + *

Format: [hrp]1[data][checksum] + * + *

Bech32 vs Bech32m

+ * + *

Two variants exist: + *

    + *
  • Bech32 (BIP-173): Original spec, used for simple data (npub, nsec, note)
    • + *
  • Bech32m (BIP-350): Updated spec, used for TLV-encoded data (nprofile, nevent)
    • + *
+ * + *

The difference is in the checksum constant used during encoding/decoding. + * + *

Usage Examples

+ * + *

Example 1: Encode a Public Key (npub)

+ * 
{@code
+ * String hexPubKey = "3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d";
+ * String npub = Bech32.toBech32(Bech32Prefix.NPUB, hexPubKey);
+ * // Returns: "npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6"
+ * }
+ * + *

Example 2: Decode an npub Back to Hex

+ * 
{@code
+ * String npub = "npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6";
+ * String hex = Bech32.fromBech32(npub);
+ * // Returns: "3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d"
+ * }
+ * + *

Example 3: Low-Level Encoding

+ * 
{@code
+ * byte[] data = hexToBytes("3bf0c63f...");
+ * byte[] fiveBitData = convertBits(data, 8, 5, true);
+ * String encoded = Bech32.encode(Bech32.Encoding.BECH32, "npub", fiveBitData);
+ * }
* - *

See BIP350 and BIP173 for details. + *

Example 4: Low-Level Decoding

+ * 
{@code
+ * Bech32Data decoded = Bech32.decode("npub180cvv07tjdrrgpa0j...");
+ * String hrp = decoded.hrp; // "npub"
+ * byte[] fiveBitData = decoded.data;
+ * Encoding encoding = decoded.encoding; // BECH32 or BECH32M
+ * }
+ * + *

Character Set

+ * + *

Bech32 uses a 32-character alphabet: qpzry9x8gf2tvdw0s3jn54khce6mua7l + * + *

This alphabet excludes: + *

    + *
  • 1, b, i, o: Visually similar to other characters
    • + *
  • Uppercase: All strings are lowercase
    • + *
+ * + *

Error Detection

+ * + *

Bech32 detects: + *

    + *
  • Any single character error
    • + *
  • Any two adjacent character swaps
    • + *
  • Most insertion/deletion errors
    • + *
  • Most multi-character errors
    • + *
+ * + *

This enum defines the Human-Readable Prefixes (HRPs) used in NIP-19 for encoding various + * Nostr entities using Bech32 format. NIP-19 specifies standardized prefixes to make Nostr + * identifiers and references human-readable and type-safe. + * + *

What is NIP-19?

+ * + *

NIP-19 defines Bech32-encoded entities for: + *

    + *
  • npub: Public keys (32 bytes hex → npub1...)
    • + *
  • nsec: Private keys (32 bytes hex → nsec1...)
    • + *
  • note: Event IDs (32 bytes hex → note1...)
    • + *
  • nprofile: Profile with metadata (public key + relays)
    • + *
  • nevent: Event reference with metadata (event ID + relays + author)
    • + *
+ * + *

Why Bech32?

+ * + *

Bech32 encoding provides: + *

    + *
  • Type safety: Prefix indicates what the string represents
    • + *
  • Error detection: Built-in checksum catches typos
    • + *
  • Human-friendly: Case-insensitive, no ambiguous characters (0/O, 1/I/l)
    • + *
  • Copy-paste safety: No special characters that break in URLs
    • + *
+ * + *

Usage Examples

+ * + *

Example 1: Encode a Public Key

+ * 
{@code
+ * String hexPubKey = "3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d";
+ * String npub = Bech32.toBech32(Bech32Prefix.NPUB, hexPubKey);
+ * // Returns: "npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6"
+ * }
+ * + *

Example 2: Encode a Private Key

+ * 
{@code
+ * byte[] privateKeyBytes = ... // 32 bytes
+ * String nsec = Bech32.toBech32(Bech32Prefix.NSEC, privateKeyBytes);
+ * // Returns: "nsec1..."
+ * }
+ * + *

Example 3: Encode an Event ID

+ * 
{@code
+ * String eventId = "a1b2c3d4..."; // 32-byte hex
+ * String note = Bech32.toBech32(Bech32Prefix.NOTE, eventId);
+ * // Returns: "note1..."
+ * }
+ * + *

Example 4: Using with PublicKey/PrivateKey

+ * 
{@code
+ * PublicKey pubKey = new PublicKey("3bf0c63fcb93...");
+ * String bech32 = pubKey.toBech32(); // Uses NPUB prefix automatically
+ *
+ * PrivateKey privKey = new PrivateKey("secret_hex...");
+ * String nsec = privKey.toBech32(); // Uses NSEC prefix automatically
+ * }
+ * + *

+ * + *

Security Considerations

+ * + *
    + *
  • NEVER share nsec: Private keys must be kept secret
    • + *
  • Validate prefixes: Check the prefix matches the expected type before using
    • + *
  • Checksum validation: Always validate the Bech32 checksum when decoding
    • + *
+ * + *

This abstract class provides a common foundation for all event types in the Nostr protocol. + * It implements the {@link IEvent} interface which defines the core contract for events, + * including event ID retrieval and Bech32 encoding support (NIP-19). + * + *

Hierarchy: + * 

+ * BaseEvent (abstract)
+ *   ├─ GenericEvent (NIP-01 implementation)
+ *   │   ├─ CustomEmojiEvent (NIP-30)

Design: This class follows the Template Method pattern, providing the base + * structure while allowing subclasses to implement specific event behavior. Most event + * implementations extend {@link nostr.event.impl.GenericEvent} which provides the full + * NIP-01 event structure. + * + *

Usage: Typically, you don't extend this class directly. Instead: + *

    + *
  • Use {@link nostr.event.impl.GenericEvent} for basic NIP-01 events
    • + *
  • Extend {@link nostr.event.impl.GenericEvent} for NIP-specific events
    • + *
  • Only extend {@code BaseEvent} directly for custom, non-standard event types
    • + *
+ * + *

Example: + * 

{@code
+ * // Most common: Use GenericEvent directly
+ * GenericEvent event = GenericEvent.builder()
+ *     .kind(Kind.TEXT_NOTE)
+ *     .content("Hello Nostr!")

Tags are metadata elements attached to Nostr events, defined as arrays in the NIP-01 + * specification. Each tag has a code (the first element) followed by one or more parameters. + * This class provides the foundation for all tag implementations in the library. + * + *

Tag Structure: + * 

{@code
+ * // JSON representation
+ * ["e", "event_id", "relay_url", "marker"]
+ *  ^     ^            ^            ^
+ *  |     |            |            |
+ * code  param0       param1      param2
+ * }
+ * + *

Common Tag Types: + *

    + *
  • e tag: References another event (EventTag)
    • + *
  • p tag: References a user's public key (PubKeyTag)
    • + *
  • a tag: References an addressable event (AddressTag)
    • + *
  • d tag: Identifier for addressable events (IdentifierTag)
    • + *
  • t tag: Hashtags (HashtagTag)
    • + *
  • r tag: References a URL (ReferenceTag)
    • + *
  • Custom tags: GenericTag for unknown tag codes
    • + *
+ * + *

Tag Creation: + * 

{@code
+ * // Method 1: Using specific tag classes
+ * EventTag eventTag = EventTag.builder()
+ *     .idEvent("event_id_hex")
+ *     .recommendedRelayUrl("wss://relay.example.com")
+ *     .marker("reply")
+ *     .build();
+ *
+ * // Method 2: Using factory method
+ * BaseTag tag = BaseTag.create("e", "event_id_hex", "relay_url", "reply");
+ *
+ * // Method 3: Using GenericTag for custom/unknown tags
+ * GenericTag customTag = new GenericTag("customcode", List.of(
+ *     new ElementAttribute("param0", "value1"),
+ *     new ElementAttribute("param1", "value2")
+ * ));
+ * }
+ * + *

Tag Registry: The library maintains a {@link TagRegistry} that maps tag codes + * to their corresponding classes. When deserializing events, the registry is consulted to + * create the appropriate tag type. Unknown tag codes are deserialized as {@link GenericTag}. + * + *

Design Patterns: + *

    + *
  • Factory Pattern: {@code create()} methods provide flexible tag creation
    • + *
  • Registry Pattern: {@link TagRegistry} maps codes to tag classes
    • + *
  • Template Method: Subclasses define specific tag fields and behavior
    • + *
+ * + *

Serialization: Tags are automatically serialized/deserialized using Jackson + * with custom {@link BaseTagSerializer} and {@link TagDeserializer}. The serialization + * preserves the tag code and parameter order required by NIP-01. + * + *

Reflection API: This class provides reflection-based methods for accessing + * tag fields dynamically: + *

    + *
  • {@link #getCode()} - Returns the tag code from {@code @Tag} annotation
    • + *
  • {@link #getSupportedFields()} - Returns fields annotated with {@code @Key}
    • + *
  • {@link #getFieldValue(Field)} - Gets field value using reflection
    • + *
+ * + *

Example - Custom Tag Implementation: + * 

{@code
+ * @Tag(code = "mycustom", name = "My Custom Tag")
+ * @Data
+ * @EqualsAndHashCode(callSuper = false)
+ * public class MyCustomTag extends BaseTag {
+ *
+ *   @Key(order = 0)
+ *   private String parameter1;
+ *
+ *   @Key(order = 1)
+ *   private String parameter2;
+ *
+ *   // Builder pattern provided by Lombok @Data
+ * }
+ *
+ * // Register the tag
+ * TagRegistry.register("mycustom", genericTag -> {
+ *   // Convert GenericTag to MyCustomTag
+ *   return MyCustomTag.builder()
+ *       .parameter1(genericTag.getAttributes().get(0).getValue())
+ *       .parameter2(genericTag.getAttributes().get(1).getValue())
+ *       .build();
+ * });
+ * }
+ * + *

Thread Safety: Tag instances are immutable after creation (due to Lombok + * {@code @Data} generating only getters for final fields).

This class represents the fundamental building block of the Nostr protocol. Events are + * immutable records signed with a private key, containing a unique ID, timestamp, kind, + * tags, and content. + * + *

NIP-01 Event Structure: + * 

{@code
+ * {
+ *   "id": "event_id_hex",        // SHA-256 hash of canonical serialization
+ *   "pubkey": "pubkey_hex",      // Author's public key
+ *   "created_at": 1234567890,    // Unix timestamp
+ *   "kind": 1,                   // Event kind (see Kind enum)
+ *   "tags": [...],               // Array of tags
+ *   "content": "...",            // Event content (text, JSON, etc.)
+ *   "sig": "signature_hex"       // BIP-340 Schnorr signature
+ * }
+ * }
+ * + *

Event Kinds: + *

    + *
  • Regular events (kind < 10,000): Immutable, stored indefinitely
    • + *
  • Replaceable events (10,000-19,999): Latest event replaces earlier ones
    • + *
  • Ephemeral events (20,000-29,999): Not stored by relays
    • + *
  • Addressable events (30,000-39,999): Replaceable with 'd' tag identifier
    • + *
+ * + *

Usage Example: + * 

{@code
+ * // Create and sign an event
+ * Identity identity = new Identity(privateKey);
+ * GenericEvent event = GenericEvent.builder()
+ *     .pubKey(identity.getPublicKey())
+ *     .kind(Kind.TEXT_NOTE)
+ *     .content("Hello Nostr!")
+ *     .tags(List.of(new HashtagTag("nostr")))
+ *     .build();
+ *
+ * event.update(); // Compute ID
+ * event.sign(identity.getPrivateKey()); // Sign with private key
+ * event.validate(); // Verify all fields are valid
+ *
+ * // Send to relay
+ * client.send(event, relayUri);
+ * }
+ * + *

Validation: This class uses a Template Method pattern for validation. + * Subclasses can override {@link #validateKind()}, {@link #validateTags()}, and + * {@link #validateContent()} to add NIP-specific validation while reusing base validation. + * + *

Serialization: Event serialization is delegated to {@link EventSerializer} + * which produces canonical NIP-01 JSON format for computing event IDs and signatures. + * + *

This class provides methods for converting event fields into the canonical JSON + * serialization required by NIP-01. The serialization is deterministic and produces + * the same output for the same inputs, which is critical for event ID computation + * and signature verification. + * + *

Canonical Format: Events are serialized as JSON arrays with specific ordering: + * 

{@code
+ * [
+ *   0,                              // Protocol version (always 0)
+ *   "pubkey_hex_string",           // 64-char public key hex
+ *   1234567890,                     // Unix timestamp (created_at)
+ *   1,                              // Event kind integer
+ *   [["e","event_id"],["p","pk"]], // Tags as array of arrays
+ *   "Event content string"          // Content (can be empty string)
+ * ]
+ * }
+ * + *

Usage: This serialization format is used for: + *

    + *
  • Event ID Computation: SHA-256 hash of the serialized event
    • + *
  • Signature Creation: BIP-340 Schnorr signature of the event ID
    • + *
  • Signature Verification: Relays recompute ID and verify signature
    • + *
+ * + *

Example: + * 

{@code
+ * // Serialize event fields
+ * String json = EventSerializer.serialize(
+ *     publicKey,
+ *     Instant.now().getEpochSecond(),
+ *     Kind.TEXT_NOTE.getValue(),
+ *     List.of(new HashtagTag("nostr")),
+ *     "Hello Nostr!"
+ * );
+ *
+ * // Compute event ID from serialization
+ * byte[] bytes = EventSerializer.serializeToBytes(...);
+ * String eventId = EventSerializer.computeEventId(bytes);
+ *
+ * // Or do both in one call
+ * String eventId = EventSerializer.serializeAndComputeId(...);
+ * }
+ * + *

Design: This class uses the Utility Pattern with static methods. It uses + * {@link EventJsonMapper} for consistent JSON configuration across the library. + * + *

Thread Safety: All methods are stateless and thread-safe. + * + *

Determinism: The serialization is deterministic - same inputs always produce + * the same output. This is essential for: + *

    + *
  • Event ID verification by relays
    • + *
  • Signature verification by other clients
    • + *
  • Duplicate event detection

This exception indicates that a cryptographic operation could not be completed successfully. + * It wraps underlying crypto library exceptions and provides context about what failed in the + * Nostr SDK. + * + *

Common Causes

+ * + *
    + *
  • Signing failed: BIP-340 Schnorr signing couldn't compute signature
    • + *
  • Verification failed: Signature verification detected invalid signature
    • + *
  • Key generation failed: Unable to generate valid key pair
    • + *
  • Invalid private key: Private key is malformed or out of range
    • + *
  • ECDH failed: Elliptic curve Diffie-Hellman key agreement failed
    • + *
  • Encryption/decryption failed: NIP-04 or NIP-44 encryption operation failed
    • + *
  • Key derivation failed: HMAC-SHA256 or other key derivation failed
    • + *
+ * + *

Usage Examples

+ * + *

Example 1: Handling Signing Failures

+ * 
{@code
+ * try {
+ *     GenericEvent event = new GenericEvent(pubKey, Kind.TEXT_NOTE);
+ *     event.setContent("Hello Nostr!");
+ *     identity.sign(event); // might throw if private key is invalid

+ *     logger.error("Failed to sign event: {}", e.getMessage(), e);
+ *     // Check if private key is valid
+ * }
+ * }
+ * + *

Example 2: Handling Verification Failures

+ * 
{@code
+ * try {
+ *     boolean valid = event.verify(); // returns false for invalid signatures
+ *     if (!valid) {
+ *         throw new NostrCryptoException("Event signature verification failed");

+ *     logger.warn("Invalid signature from {}: {}", event.getPubKey(), e.getMessage());
+ *     // Reject the event
+ * }
+ * }
+ * + *

Example 3: Handling Encryption Failures

+ * 
{@code
+ * try {
+ *     String encrypted = NIP44.encrypt(identity, "secret message", recipientPubKey);
+ * } catch (NostrCryptoException e) {
+ *     logger.error("Encryption failed: {}", e.getMessage(), e);
+ *     // Check if recipient public key is valid
+ * }
+ * }
+ * + *

Recovery Strategies

+ * + *
    + *
  • Signing failures: Validate the private key format, regenerate identity if corrupted
    • + *
  • Verification failures: Reject the event, don't trust unverified content
    • + *
  • Key generation: Retry with proper entropy source
    • + *
  • Encryption failures: Validate public keys, check algorithm compatibility
    • + *
+ * + *

Security Implications

+ * + *
    + *
  • Never ignore crypto exceptions: They indicate security-critical failures
    • + *
  • Log failures: Crypto exceptions may indicate attacks (signature forgery attempts)
    • + *
  • Fail secure: Reject events/operations on crypto failures (don't proceed)
    • + *
  • Key protection: Ensure private keys are stored securely to prevent failures

+ * }
+ * + *

Recovery Strategies

+ * + *
    + *
  • JSON parsing: Validate JSON structure, log and ignore malformed messages
    • + *
  • Bech32 decoding: Validate format (npub/nsec/note prefix), show user-friendly errors
    • + *
  • Hex conversion: Validate length (64 chars for keys, 32 bytes) and charset
    • + *
  • User input: Provide clear validation messages (\"Invalid public key format\")

Common Causes

+ * + *
    + *

Recovery Strategies

+ * + *
    + *
  • Connection failures: Retry with exponential backoff, use backup relays
    • + *
  • Timeouts: Increase timeout, use faster relays, implement parallel sends

Common Causes

+ * + *
    + *
  • Invalid event structure: Missing required fields (id, pubkey, created_at, kind, tags, content, sig)

This is the root of the exception hierarchy for nostr-java. All exceptions thrown by this + * SDK extend from {@code NostrRuntimeException}, making it easy to catch all Nostr-specific errors + * with a single catch block. + * + *

Exception Hierarchy

+ * + * 
+ * NostrRuntimeException (base)
+ *  ├── NostrProtocolException (protocol violations, invalid events/messages)
+ *  │    └── NostrException (legacy, deprecated)
+ *  ├── NostrCryptoException (signing, verification, key generation failures)
+ *  ├── NostrEncodingException (JSON/Bech32/hex encoding/decoding failures)
+ *  └── NostrNetworkException (relay connection, WebSocket, timeout failures)
+ *
+ * + *

Design Principles

+ * + *
    + *
  • Unchecked exceptions: All exceptions extend {@link RuntimeException} (no forced try-catch)
    • + *
  • Domain-specific: Each subclass represents a specific failure domain
    • + *
  • Fail fast: Validation errors are thrown immediately (not silently ignored)
    • + *
  • Context-rich messages: Exceptions include detailed context for debugging
    • + *
+ * + *

When to Use

+ * + *

You should catch {@code NostrRuntimeException} when: + *

    + *
  • You want to catch all Nostr-related errors
    • + *
  • You need to distinguish Nostr errors from other exceptions
    • + *
  • You're implementing error boundaries in your application
    • + *
+ * + *

Prefer catching specific subclasses when: + *

    + *
  • You can handle specific error types differently
    • + *
  • You want to retry on network errors but fail on protocol errors
    • + *
  • You need fine-grained error handling
    • + *
+ * + *

Usage Examples

+ * + *

+ *     logger.error("Nostr operation failed: {}", e.getMessage(), e);
+ *     // Handle any Nostr-related error

Exception TypeWhen ThrownExamples
{@link NostrProtocolException}NIP violations, invalid eventsInvalid kind, missing required tags, bad event structure
{@link NostrCryptoException}Cryptographic failuresSchnorr signing failed, invalid signature, key derivation error
{@link NostrEncodingException}Serialization/deserialization errorsInvalid JSON, Bech32 decode failed, hex conversion error
{@link NostrNetworkException}Network/relay communication errorsConnection timeout, WebSocket closed, relay rejected event

Best Practices

+ * + *
    + *
  • Use specific exceptions: Throw the most specific subclass that applies
    • + *
  • Include context: Exception messages should describe what failed and why
    • + *
  • Chain exceptions: Use {@code new NostrException("msg", cause)} to preserve stack traces
    • + *
  • Document throws: Use {@code @throws} in JavaDoc to document expected exceptions
    • + *
+ * + * @see NostrProtocolException + * @see NostrCryptoException + * @see NostrEncodingException + * @see NostrNetworkException + * @since 0.1.0 + */ +@StandardException +public class NostrRuntimeException extends RuntimeException {} diff --git a/nostr-java-util/src/main/java/nostr/util/validator/HexStringValidator.java b/nostr-java-util/src/main/java/nostr/util/validator/HexStringValidator.java index 41898f169..a3d223725 100644 --- a/nostr-java-util/src/main/java/nostr/util/validator/HexStringValidator.java +++ b/nostr-java-util/src/main/java/nostr/util/validator/HexStringValidator.java @@ -1,10 +1,11 @@ package nostr.util.validator;
