 List of IPsec Proposal
In this table, you can view the information of IPsec Proposals and edit them by the action buttons.
Select the security protocol to be used. Options include:
AH: AH (Authentication

authentication, data integrity and anti-replay services.
ESP: ESP (Encapsulating Security Payload) provides data

encryption in addition to origin authentication, data integrity, and
anti-replay services.
Select the algorithm used to verify the integrity of the data for AH
authentication. Options include:
MD5: MD5 (Message Digest Algorithm) takes a message of

arbitrary length and generates a 128-bit message digest.
SHA: SHA (Secure Hash Algorithm) takes a message less than the

64th power of 2 in bits and generates a 160-bit message digest.

Select the algorithm used to encrypt the data for ESP encryption.
Options include:
NONE: Performs no encryption.
DES: DES (Data Encryption Standard) encrypts a 64-bit block of plain
text with a 56-bit key. The key should be 8 characters.
3DES: Triple DES, encrypts a plain text with 168-bit key. The key should
be 24 characters.
AES128: Uses the AES algorithm and 128-bit key for encryption. The
key should be 16 characters.
