HashKit

HashKit is a C library for cryptographic hashing algorithms. It provides implementations for various hashing algorithms such as SHA-2 and MD5.

Features

• SHA-1: Secure Hash Algorithm 1 implementation.
• SHA-2: Secure Hash Algorithm 2 implementation.
• MD5: Message-Digest Algorithm 5 implementation

Installation

1. Clone the repository:

   git clone https://github.com/MKKHLIF/HashKit.git
   cd HashKit

2. Build the library:

    mkdir build
    cd build
    cmake ..
    make

Usage

#include <stdio.h>
#include <stdint.h>
#include <string.h>
#include <stdlib.h>
#include "sha2.h"

    for (size_t i = 0; i < len; i++) {
        if (expected[i] != actual[i]) {
            printf("Mismatch at byte %zu\n", i);
            return;
        }
    }
    printf("Hashes match!\n");
}

int main() {

    for (size_t i = 0; i < sizeof(sha384_digest); i++) printf("%02x", sha384_digest[i]);
    printf("\n");
    
    printf("SHA-512: ");
