Crate BlueHash 

BlueHash: A cryptographic hash function with quantum-resistant features. This library implements the BlueHash algorithm, designed to resist quantum attacks while maintaining high security. It includes state manipulation, constant generation, and noise-based perturbations inspired by lattice-based cryptography.

BlueHash Usage Example (BlueHash128)

use BlueHash::DigestSize;
use std::fmt::Write;
use BlueHash::Digest;
use BlueHash::BlueHashCore;

fn main() {
let test_data = b"Hello, world! This is a test message for BlueHash";
    let mut hasher128 = BlueHashCore::new(DigestSize::Bit128);
    hasher128.update(test_data);
    let result128 = hasher128.finalize();
    println!("BlueHash128 Result: {}", to_hex_string(&result128));
}

// Helper function to convert bytes to a hexadecimal string
fn to_hex_string(bytes: &[u8]) -> String {
    let mut hex = String::new();
    for byte in bytes {
        write!(&mut hex, "{:02x}", byte).unwrap();
    }
    hex
}
