Key-Out The encryption key for the outbound policy. The length of the key depends on
the selected encryption algorithm:
3DES.
Enter 24 characters.
None. Key
does not apply.
DES. Enter 8 characters.
AES-128.
Enter 16 characters.
AES-192.
Enter 24 characters.
AES-256. Enter 32 characters.
SPI-Outgoing The Security Parameters Index (SPI) for the outbound policy. Enter a
hexa
decimal value between 3 and 8 characters (for example, 0x1234).
Integrity Algorithm From the drop-down list, select one of the follo
wing two algorithms to be used in
the VPN header for the authentication process:
SHA-1.
Hash algorithm that produces a 160-bit digest. This is the default
setting.
MD
5. Hash algorithm that produces a 128-bit digest.
Key-In The integrity key for the inbound policy. The length of the key depends on the
selected integrity algorithm:
MD
5. Enter 16 characters.
SHA-1.
Enter 20 characters.
Key-Out The integrity key for the outbound policy. The length of the key depends on the
selected integrity algorithm:
MD
5. Enter 16 characters.
SHA-1.
Enter 20 characters.
Auto Policy Parameters
Note: These fields apply only when you select Auto Policy as the policy type.
SA Lifetime The lifetime of the security association (SA) is th
e period or the amount of
transmitted data after which the SA becomes invalid and needs to be
renegotiated. From the drop-down list, select how the SA lifetime is specified:
Seconds. In the SA Lifetime fiel
d, enter a period in seconds. The minimum
value is 300 seconds. The default setting is 3600 seconds.
KBy
tes. In the SA Lifetime field, enter a number of kilobytes. The minimum
value is 1920000 KB.
Encryption Algorithm From the drop-down list, select one of the
following five algorithms to negotiate
the security association (SA):
3DES. T
riple DES. This is the default algorithm.
None. No
encryption algorithm.
DES. Dat
a Encryption Standard (DES).
AES-128.
Advanced Encryption Standard (AES) with a 128-bit key size.
AES-192. AES with a
192-bit key size.
AES-256. AES with a 256-bit key size.
