    HMAC-SHA-256 and HMAC-SHA-512 for AssemblyScript

    Self-contained implementations of SHA-256, SHA-512, HMAC-SHA-256 and HMAC-SHA-512 for AssemblyScript.

    Simple hashing:

    let msg = Uint8Array.wrap(String.UTF8.encode("test"));
    let h = Sha256.hash(msg);

    Chunked input:

    let st = new Sha256();
    st.update(msg1);
    st.update(msg2);
    let h = st.final();

    HMAC:

    let msg = Uint8Array.wrap(String.UTF8.encode("message"));
    let key = Uint8Array.wrap(String.UTF8.encode("key"));
    let mac = Sha256.hmac(msg, key);

    Constant-time check for equality:

    let ok = verify(mac, expected_mac);

    Constant-time hexadecimal encoding/decoding:

    let hex = bin2hex(h);
    let bin = hex2bin(hex);
