I am working on SAML Authentication through ADFS. Code is in Perl CGI and I am relatively new to Perl CGI.

I am able to get SAMLResponse back but struggling to get its signature/hash validated.

In CPAN, its mentioned that required methods for authentication are in Crypt::OpenSSL::RSA library. However, some important methods like _load_public_x509_key, verify, etc are not present in this library.

Request you to please help me on this. Please help me get RSA library with _load_public_x509_key, verify, etc subroutines. Also, please share some knowledge/implementation on xml authentication in Perl.

Thanks in Advance !!!
