I don't understand this remark. Aren't you doing the cert verfication in the
callback? Are you going to return from the callback without being done and
then somehow keep verifying "in the background" ?

Sorry, but I don't. I don't understand how these OpenSSL APIs work and I don't
understand how you envision this should work together with libcurl even if
everything worked the way you wanted them to!
