WARNING
No library for handling international domain names found.
It will work but croak if you try to verify an international name against
a certificate.
It's recommended to install either Net::IDN::Encode, Net::LibIDN or URI version>=1.50

# check Version

WARNING
You have version $Net::SSLeay::VERSION of Net::SSLeay.
Support for subjectAltNames in certificates is only available in Version >=1.33
so verifying a hostname against the certificate will not work.
It is recommended to upgrade to a current Net::SSLeay.
