Cryptographic doom principle
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. http://gauss.ececs.uc.edu/Courses/c6053/lectures/PDF/ssl.pdf

WebIt boils down to Moxie Marlinspike's Cryptographic Doom Principle, which states: If you have to perform any cryptographic operation before verifying the MAC on a message you’ve received, it will somehow inevitably lead to doom. With the AES-CBC as implemented in TLS 1.2, an HMAC of the plaintext (and header information) is taken.
