SHA-512 Implementation

A C implementation of the SHA-512 cryptographic hash function. This project provides a simple and efficient way to generate SHA-512 hashes for input data.

Features

• Pure C implementation of SHA-512
• Handles input data of any length
• Produces 512-bit (64-byte) hash output
• Includes proper padding and message scheduling

Building

To build the project, simply run:

make

This will create an executable named sha512.

Usage

./sha512 < input_file

The program reads input from stdin and outputs the SHA-512 hash in hexadecimal format.

Cleanup

To clean up build artifacts:

make clean

Implementation Details

The implementation follows the SHA-512 specification as defined in FIPS 180-4, including:

• Message padding
• Message scheduling
• Compression function
• Final hash computation
