because neither M2crypto nor OpenSSL packages provide extensive
enough API to do certificate chain building, verification
and outputting of details, we have to pre-parse the data
with a C app that can access the full OpenSSL API.
I've also tried monkey patching the packages, but unfortunately
the result wasn't working reliably
The actual statistic collection (both about the chains and
specific certificates) will be done in a python script
