       Crypt::SSLeay::Version - Obtain OpenSSL version information

SYNOPSIS

           use Crypt::SSLeay::Version qw(\
               openssl_built_on
               openssl_cflags
               openssl_dir
               openssl_platform
               openssl_version
               openssl_version_number
           );

           my $version = openssl_version();

           if (openssl_cflags() =~ /DOPENSSL_NO_HEARTBEATS/) {
               print "OpenSSL was compiled without heartbeats\n";
           }

SUMMARY

       Exposes information provided by SSLeay_version
       <https://www.openssl.org/docs/crypto/SSLeay_version.html>.

EXPORTS

       By default, the module exports nothing. You can ask for each subroutine bloew to be
       exported to your namespace.

SUBROUTINES

   openssl_built_on
       The date of the build process in the form "built on: ..." if available or ``built on: date
       not available'' otherwise.

   openssl_cflags
       The compiler flags set for the compilation process in the form "compiler: ..." if
       available or "compiler: information not available" otherwise.

   openssl_dir
       The "OPENSSLDIR" setting of the library build in the form "OPENSSLDIR: ..." if available
       or "OPENSSLDIR: N/A" otherwise.

   openssl_platform
       The "Configure" target of the library build in the form "platform: ..." if available or
       "platform: information not available" otherwise.

   openssl_version
       The version of the OpenSSL library including the release date.

   openssl_version_number
       The value of the "OPENSSL_VERSION_NUMBER" macro as an unsigned integer. This value is more
       like a string as version information is packed into specific nibbles see
       "crypto/opensslv.h" in the OpenSSL source and
       <https://metacpan.org/pod/OpenSSL::Versions|OpenSSL::Versions> for explanation.
