hash_hmac

WMMEGA FW >= 2.1030 WM2 FW >= 3.1130

Generate a keyed hash value using the HMAC method

This can be used for cryptography or just for checksum calculations.

$algorithm: Name of selected hashing algorithm. Current algorithms supported are:

$data: String of characters to calculate hash for

$key: String of characters of key to be used in hash calculation

String: Hash result (as hexadecimal number) of data. See above for expected length
