This repository is dedicated to exploring and implementing various cryptographic hash functions in Rust, starting with SHA-1. The primary goal of this project is educational, aimed at understanding the mechanisms and applications of hash functions in cryptography.
Ensure you have Rust installed. If not, you can install it by following the instructions on the official Rust website.
Clone the repository to begin exploring the hash functions:
git clone https://github.com/bp7968h/cryptography.git
cd cryptographySHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function which produces a 160-bit hash value known as a message digest. Although SHA-1 has been found to be vulnerable to certain types of attacks and is no longer recommended for security-critical cryptographic purposes, it remains widely used for general checksum purposes and in non-critical applications due to its speed.
To use the SHA-1 function in your Rust code, first ensure you have the library included in your Cargo.toml:
[dependencies]
cryptography = { git = "https://github.com/bp7968h/cryptography.git" }
Then, you can compute a SHA-1 hash as follows:
use cryptography::SHA1;
fn main() {
let mut sha1 = SHA1::new();
let result_arr: Vec<u8> = sha1.hash("example");
let result = result_arr.iter().map(|b| format!("{:02x}", b)).collect::<String>();
println!("SHA-1 hash: {}", result);
}
