System Administration Guide: IP Services


This option enables IPsec ESP for a tunnel with the encryption algorithm specified. The option has the following format:

encr_algs encryption_algorithm

For the algorithm, you can specify either a number or an algorithm name. You must specify all IPsec tunnel properties on the same command line. To disable tunnel security, specify the following option:

encr_alg none

If you specify an ESP authentication algorithm, but not an encryption algorithm, the ESP encryption value defaults to the parameter null.

See the ipsecesp(7P) man page or Table 19–2 for a list of available encryption algorithms and for pointers to the algorithm man pages.
