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

<https://metacpan.org/pod/OpenSSL::Versions|OpenSSL::Versions> for
explanation.
