Yes - it is - that is exactly what Pathfinder does - it just takes a
certificate from the SSL and/or X509_verify callback (also works with
Netscape Security Services). As I said in my previous email, you may want to
look at using that, given it is a rather difficult task, so instead of
re-inventing the wheel, you may want to re-use the code that we have in
Pathfinder. It is licensed under the LGPL with an OpenSSL permissive clause,
so even if you want to include the code in a proprietary application, that
shouldn't cause you any problems.
If you want to discuss this more, please contact me off-list.
