> 1. Does strongSwan 4.6.1 comply with NIST SP800-131a?
I haven't read that spec in detail, but it seems that it just defines
algorithms and key lengths to use for "acceptable" operation.
strongSwan can support many of these algorithms and key lengths, it's
just a matter of configuration. Make sure to define the algorithms you
require in your connections in the "esp" and "ike" proposal keywords,
and append a '!' to disable others (man ipsec.conf for details).
If you are using certificates, generate the the keys with appropriate
key length and sign the certificates with the required hashing
So yes, it should be possible to configure strongSwan for NIST
SP800-131a compliance (but it is also possible to configure it to
violate this spec).

I don't think that the selection of the crypto backend matters, you can
use weak algorithms or key lengths with any backend.
