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

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.

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.
