=head1 NAME
Crypt::SSLeay::Version - Obtain OpenSSL version information
=head1 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";
}
=head1 SUMMARY
Exposes information provided by L<SSLeay_version|https://www.openssl.org/docs/crypto/SSLeay_version.html>.

The date of the build process in the form "built on: ..." if available or ``built on: date not available'' otherwise.
=head2 openssl_cflags
The compiler flags set for the compilation process in the form "compiler: ..." if available or "compiler: information not available" otherwise.
=head2 openssl_dir
The C<OPENSSLDIR> setting of the library build in the form "OPENSSLDIR: ..." if available or "OPENSSLDIR: N/A" otherwise.
=head2 openssl_platform
The "Configure" target of the library build in the form "platform: ..." if available or "platform: information not available" otherwise.
=head2 openssl_version
The version of the OpenSSL library including the release date.
=head2 openssl_version_number
The value of the C<OPENSSL_VERSION_NUMBER> macro as an unsigned integer. This value is more like a string as version information is packed into specific nibbles see C<crypto/opensslv.h> in the OpenSSL source and L<https://metacpan.org/pod/OpenSSL::Versions|OpenSSL::Versions> for explanation.
