crypt::ssleay question

Dear Sirs:
A how to question:
I am trying to access certificates on my Mac laptop using
lwp::useragent, openssl, crypt::ssleay in perl.  I have populated the
$ENV variables to define where the files are located on my machine.
 
How do I use the Crypt::SSLeay::CTX, Conn, and X509 methods to access
these files, and extract the different parts of a certificate?
 
Right now I am just trying to write a prototype perl program so that can
I understand how the methods  work and then use them in the near future
in a larger application.
 
Let me know if I need to give you any other info.
 
Thanks for your timely reply to my questions.
