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). WebBackground. This article outlines Check Point versions that support SHA-256 certificates for SIC and for VPN. In R77.X and lower versions, by default, the Internal CA (ICA) issues certificates based on the SHA-1 algorithm. In R80.xx, by default, the SHA-256 signature algorithm signs the Internal Certificate Authority (ICA).
