Manual Policy Parameters
If you chose manual as the policy type in Step 4, configure the manual policy
parameters. The Manual Policy creates an SA (Security Association) based on the
following static inputs:
SPI-Incoming, SPI-Outgoing—Enter a hexadecimal value between 3 and 8
characters; for example, 0x1234.
Encryption Algorithm—Select the algorithm used to encrypt the data.
•
Key-In—Enter the encryption key of the inbound policy. The length of the
key depends on the algorithm chosen:
-
DES—8 characters
-
3DES—24 characters
-
AES-128—16 characters
-
AES-192—24 characters
-
AES-256—32 characters
-
AES-CCM—16 characters
-
AES-GCM—20 characters
•
Key-Out—Enter the encryption key of the outbound policy. The length of the
key depends on the algorithm chosen, as shown above.
Integrity Algorithm—Select the algorithm used to verify the integrity of the data.
•
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
-
SHA2-384— 48 characters
-
SHA2-512—64 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.
