WebIPSec is defined by the IPSec working group of the IETF. It provides authentication, integrity, and data privacy between any two IP entities. Management of cryptographic keys and Security Associations can be either manual or dynamic using an IETF-defined key management protocol called Internet Key Exchange (IKE). WebIntegrity: Integrity is used to make sure that nobody in between site A and B (for example) changed some parts of the shared information. Therefore a hash is calculated and added to a packet. This can be achieved by using hashing algorithms like MD5, SHA (1,2) and so on.
