Computes a Hash-based Message Authentication Code (HMAC)
for the input data using the specified hash function.

Remarks
HMAC is defined by RFC 2104 and look like this:
alg(K XOR opad + alg(K XOR ipad + text))
where alg is the base hash algorithm,
K is an n byte key,
ipad is the byte 0x36 repeated 64 times (or 128 times),
opad is the byte 0x5c repeated 64 times (or 128 times),
and text is the data being protected.
