Parameters:

digestAlg - The digestAlgorithm to be used.

Returns:

the message authentication code produced with digestAlg.

Raises:

RANGE_ERROR - If message contains a character beyond '\255;'.

const func string: p_hash (in digestAlgorithm: digestAlg, in string: secret, in string: seed, in integer: length)

Data expansion function based on the message authentication (hmac) of digestAlg.

Parameters:

digestAlg - The digestAlgorithm to be used.

Returns:

a pseudo random string of the given length.
