Crypt::OpenSSL::X509 - Perl extension to OpenSSL's X509 API.
This implement a large majority of OpenSSL's useful X509 API. The email() method supports both certificates where the subject is of the form: "... CN=Firstname lastname/emailAddress=user@domain", and also certificates where there is a X509v3 Extension of the form "X509v3 Subject Alternative Name: email=user@domain".
None by default.
