AES is used for encrypting IPsec connections, preferably ENCR_AES_GCM_16.

The Internet Key Exchange version 1 (IKEv1) protocol was obsoleted by the IKE version 2 (IKEv2) protocol in December 2005. Since IKEv2 has now been widely adopted, and in doing so addresses various problems with IKEv1, approval for the use of IKEv1 as part of Internet Protocol security implementations has been rescinded.
