## 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();

## 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.
