Cryptographic Suites for IPsec, December 2005
Discuss this RFC: Send questions or comments to firstname.lastname@example.org
The IPsec, Internet Key Exchange (IKE), and IKEv2 protocols rely on security algorithms to provide privacy and authentication between the initiator and responder. There are many such algorithms available, and two IPsec systems cannot interoperate unless they are using the same algorithms. This document specifies optional suites of algorithms and attributes that can be used to simplify the administration of IPsec when used in manual keying mode, with IKEv1 or with IKEv2.
