WebNov 7, 2016 · The NULL encryption algorithm is a convenient way to represent the option of not applying encryption. Today, where VPNs are always encrypted regardless of the data, NULL has only a meaning for learning IPsec which gives you the option to look at the data in Wireshark. BTW: You are mixing up the phases of IPsec. "crypto isakmp ..." WebIPsec can protect our traffic with the following features: Confidentiality: by encrypting our data, nobody except the sender and receiver will be able to read our data. Integrity: we want to make sure that nobody changes the data in our packets.
