  But user sets SAD for ipsec with "ip xfrm state ..." must use the name such as "rfc3686(ctr(aes))".
  Is that reasonable? Maybe user can not remember this complex name.

  There are some simple names for other encryptions, 
  such as "cbc(blowfish)", you can use "ip xfrm state ... enc blowfish ...".
