WebUsing GCM on two different messages with the same key and nonce basically allows an attacker to decrypt both messages and forge further messages. (There are some limitations, but they aren't significant enough for it not to be devastating to the cryptosystem.) WebGCM is defined for the tag sizes 128, 120, 112, 104, or 96, 64 and 32. Note that the security of GCM is strongly dependent on the tag size. You should try and use a tag size of 64 bits at the very minimum, but in general a tag size of the full 128 bits should be preferred.
