NAME
    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.
