public static class MacUtilities

Factory for IMac instances (HMAC, CMAC, GMAC, Poly1305, etc.) and convenience helpers for one-shot MAC computation.

public static byte[] CalculateMac(string algorithm, ICipherParameters cp, byte[] input)

One-shot MAC of input using the named algorithm and the supplied key parameters.

public static byte[] DoFinal(IMac mac)

Finalises mac and returns the resulting tag as a fresh array.

public static byte[] DoFinal(IMac mac, byte[] input)

Feeds input into mac, then finalises and returns the tag.

Returns the canonical algorithm name registered for the given ASN.1 OID, or null if the OID is not mapped to a known MAC.

Resolve and instantiate an IMac for the given ASN.1 algorithm OID.

public static IMac GetMac(string algorithm)

Resolve and instantiate an IMac by name (or alias).
