# AutoKey IKE P1 Proposal List

Setting up virtual private network (VPN) tunnel encryption and authentication is a two-phase process:

-  Phase 1 determines how the gateways securely negotiate and handle building the tunnel. The Phase 1 proposal sets the terms of the negotiation.

-  Phase 2 determines how data passing through the tunnel is encrypted at one end and decrypted at the other. The encryption method you choose needs to account for both phases. This process is carried out on both sides of the tunnel. The Phase 2 proposal sets the terms of the negotiation.

DH Group: Indicates the Diffie-Hellman (DH) group used: Group 1, Group 2, or Group 5.

Encrypt/Auth: Indicates the encryption algorithm used (3DES-CBC, DES-CBC, or AES-CBC) and the hash algorithm used (MD5 or SHA-1).

Life Time: Indicates the life of the key, as determined by the amount of time in Sec (seconds), Min (minutes), Hours, or Days.
