Integrity (MAC) Specifies which IKE Integrity (MAC) algorithm the device uses.
In order to help keep the information on the VPN secure, the Hash-based
Message Authentication Code (HMAC) process mixes (hashes) a shared
secret key with the message data. The device mixes the results (hash
value) with the secret key again, and then applies the hash function a
second time.
Possible values:
any
With this value selected the device accepts every algorithm when
specified as the responder and uses various pre-defined algorithms
when specified as the initiator.
hmacmd5
The device uses the Message Digest Algorithm 5 (MD5) for the hash
function calculation.
hmacsha1
(default setting)
The device uses the Secure Hash Algorithm version 1 (SHA-1) for the
hash function calculation.
hmacsha256
The device uses SHA-256, part of the version 2 family, for hash function
calculation which the device computes with 32-bit words.
hmacsha384
The device uses SHA-384, part of the version 2 family, for hash function
calculation which the device computes using a shorter version of SHA-
512.
hmacsha512
The device uses SHA-512, part of the version 2 family, for hash function
calculation which the device computes with 64 bit words.
Encryption Specifies the IKE encryption algorithm that the device uses.
Possible values:
any
The device accepts every algorithm when you specify it to be a
responder, and uses various pre-defined algorithms as the initiator.
des
The device uses the Data Encryption Standard (DES) block cipher for
encryption of message data with a 56-bit key.
des3
The device uses the Triple DES block cipher for encryption of message
data which applies the 56-bit key, from DES, 3 times to each block.
aes128
(default setting)
The device uses the Advanced Encryption Standard (AES) with a block
size of 128 bits, and a key length of 128 key bits.
aes192
The device uses the Advanced Encryption Standard (AES) with a block
size of 128 bits, and a key length of 192 key bits.
aes192
The device uses the Advanced Encryption Standard (AES) with a block
size of 128 bits, and a key length of 256 key bits.
