Did you know?
WebGCM is defined for block ciphers with a block size of 128 bits. Galois Message Authentication Code ( GMAC) is an authentication-only variant of the GCM which can form an incremental message authentication code. Both GCM and GMAC can accept initialization vectors of arbitrary length.
