# AutoKey IKE P2 Proposal List

Setting up VPN tunnel encryption and authentication is a two-phase process.

- Phase 1 determines how the gateways securely negotiate and handle building of 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.

Encap: Indicates the type of encapsulation: Encryption (ESP) or Authentication Only (AH).

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

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

Life Size: Indicates the lifetime of the key by the number of kilobytes of VPN traffic.
