WebJul 11, 2013 · In principle there's no difference between a MAC (symmetric-key) vs signature (asymmetric-key). In practice there is one difference: it is rare to find symmetric-key … WebIf you have to perform any cryptographic operation before verifying the MAC on a message you’ve received, it will somehow inevitably lead to doom. GCM, for instance, does not violate this principle, so it is vastly preferred. RSA on the other hand does not support forward secrecy, which is a VERY useful feature when it comes to cryptography. flying to australia from usa
