hex-key: Encryption key for the SA, in hexadecimal format. The length of the key is 8 bytes for DES and
24 bytes for 3DES.
Description
Use the sa encryption-hex command to configure an encryption key for an SA.
Use the undo sa encryption-hex command to remove the configuration.
This command applies to only manual IPsec policies.
When configuring a manual IPsec policy, you must set the parameters of both the inbound and outbound
SAs.
The encryption key for the inbound SA at the local end must be the same as that for the outbound SA at
the remote end, and the encryption key for the outbound SA at the local end must be the same as that for
the inbound SA at the remote end.
With an IPsec policy for an IPv6 routing protocol, the local SPI of the inbound SA and that of the
outbound SA must be identical.
At both ends of an IPsec tunnel, the keys for the inbound and outbound SAs must be in the same format.
Related commands: ipsec policy.
Examples
# Configure the encryption key for the inbound and outbound SAs using ESP as 0x1234567890abcdef
and 0xabcdefabcdef1234 respectively.
