Encryption Algorithm Select the algorithm used to encrypt the data: DES,
3DES, AES-128, AES-192, or AES-256.
Key-In Enter the encryption key of the inbound policy. The
length of the key depends on the encryption algorithm
chosen:
• DES: 8 characters
• 3DES: 24 characters
• AES-128: 16 characters
• AES-192: 24 characters
• AES-256: 32 characters
Key-Out Enter the encryption key of the outbound policy. The
length of the key depends on the encryption algorithm
chosen, as shown above.
Integrity Algorithm Select the algorithm used to verify the integrity of the
data: MD5, SHA-1, or SHA2-256.
Key-In Enter the integrity key (for ESP with Integrity-mode) for
the inbound policy. The length of the key depends on
the algorithm chosen:
• MD5: 16 characters
• SHA-1: 20 characters
• SHA2-256: 32 characters
Key-Out Enter the integrity key (for ESP with Integrity-mode) for
the outbound policy. The length of the key depends on
the algorithm chosen, as shown above.
Auto Policy Parameters
For an Auto policy type, enter the settings in the Auto Policy Parameters area.
SA-Lifetime Enter the duration of the Security Association (SA) in
seconds. After the specified number of seconds
passes, the Security Association is renegotiated. The
default value is 3600 seconds. The minimum value is
300 seconds.
Encryption Algorithm Select the algorithm used to encrypt the data.
