Description

This is a signing mechanism with a CK_AES key.

Used by IPsec. GCM (Galois/Counter Mode) for Message Authentication Code (MAC).
It is a special case of GCM: The MAC is computed on the "Additional Authenticated Data" passed in via the mechanism parameter. There is no plaintext or ciphertext.
