dataMessage to be hashed.

keyShared secret key used for generating the HMAC variant of the message digest.

binaryWhen set to true, outputs raw binary data. false outputs lowercase hexits.

Returns a string containing the calculated message digest as lowercase hexits unless is set to true in which case the raw binary representation of the message digest is returned. binary
