That only works for SSL/TLS ciphersuites. If the OP really means ciphers and
digests then this is possible, there are two new options
list-message-digest-algorithms and list-cipher-algorithms in OpenSSL 0.9.9
which do this, they use a couple of new functions derived from
OBJ_name_do_all().
Yes, I'm trying to update my code that creates PostgreSQL data types and
functions using OpenSSL. Some of the advanced functions (e.g., rekeying
an PKCS8 object) require that the user pass in things like digest names,
but my interface doesn't yet support a way of learning what those
possible values are.
I'm building against Debian and it's still 0.9.7. Is it hard to use
OBJ_name_do_all()?
Hmm, I guess the worst-case scenario is that I return a staic list until
the next Debian release. The nature of the beast means that there will
be a lot of inertia and a strong preference for proven selections.
Thanks,
Bear
