Noir Hmac Auth

This project implements HMAC (Hash-Based Message Authentication Code) authentication using a generic interface for supported hash algorithm.

Usage

In your Nargo.toml file, add the following dependency:

[dependencies]
hmac = { git = "https://github.com/0xnonso/noir-hmac-auth" }

Then use it in your Noir project like this:

use dep::hmac::types::HHSha256;
use dep::hmac::types::HmacHasherSha256;

fn main(key: [u8; 40], message: [u8; 128], expected_mac_tag: [u8; 32]) {
    let H: HHSha256 = HmacHasherSha256 {};
    assert(expected_mac_tag == H.hmac(key, message));
}
