WebAug 10, 2015 · Secure Hash Algorithm 1: The Secure Hash Algorithm 1 (SHA-1) is a cryptographic computer security algorithm. It was created by the US National Security Agency in 1995, after the SHA-0 algorithm in 1993, and it is part of the Digital Signature Algorithm or the Digital Signature Standard (DSS).
WebFor SHA1 in IpSec, it's either 2^160 possible values that the key can have (if the attacker has the key, he can generate HMACs for all received messages, ie. give you as much garbage as he wants), or 2^96 possible values for the hash itself (if the attacker manages to get that, just one block can be changed).
