extendhash
extendhash is a Rust library to compute hash extensions. Currently only MD5 is supported, but more hash algorithms are planned in the future.
Usage
use MD5;
let secret_data = "This is a secret!";
let hash = MD5 compute_hash;
let secret_data_length = secret_data.len;
// Now we try computing a hash extension, assuming that `secret_data`
// is not available. We only need `hash` and `secret_data_length`.
let appended_message = "Appended message.";
let combined_hash = MD5 extend_hash;
// Now we verify that `combined_hash` matches the concatenation (note the intermediate
// padding):
let mut combined_data = Vec:: new;
combined_data.extend_from_slice;
combined_data.extend_from_slice;
combined_data.extend_from_slice;
assert_eq!;
