Usage

Here is a simple example that demonstrates how to use SpongeHash-AES256 in your code:

use sponge_hash_aes256::{DEFAULT_DIGEST_SIZE, SpongeHash256};

fn main() {
    // Create new hash instance
    let mut hash = SpongeHash256::new();

    // Process message
    hash.update(b"The quick brown fox jumps over the lazy dog");

    // Retrieve the final digest
    let digest = hash.digest::<DEFAULT_DIGEST_SIZE>();

    // Print result
    println!("{:02X?}", &digest);
}
