Hierarchy Level
[edit security ipsec security-association sa-name manual direction (inbound | outbound | bidirectional)]
Release Information
Statement introduced before JUNOS Release 7.4.
Description
Configure an encryption algorithm and key for manual SA.
Options
algorithm—Type of encryption algorithm. It can be one of the following:
- des-cbc—Has a block size of 8 bytes (64 bits); its key size is 48 bits long.
- 3des-cbc—Has block size of 8 bytes (64
bits); its key size is 192 bits long.

Note: For 3des-cbc, we recommend that the first 8 bytes be different from the second 8 bytes, and the second 8 bytes be the same as the third 8 bytes.
key—Type of encryption key. It can be one of the following:
- ascii-text—ASCII text key. For the des-cbc option, the key contains 8 ASCII characters; for 3des-cbc, the key contains 24 ASCII characters.
- hexadecimal—Hexadecimal key. For the des-cbc option, the key contains 16 hexadecimal characters; for the 3des-cbc option, the key contains 48 hexadecimal characters.
