This is very cheesy but I sometimes I've just run the openssl command
line utility with popen and read the output:

  openssl x509 -text -noout -in certfile

will dump out the cert contents and you can parse it with regexps.

The right way to do it is to make the appropriate m2crypto (or
whatever) calls that parse the cert directly.
