Crypt::SSLeay::Version − Obtain OpenSSL version information
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";
}
Exposes information provided by SSLeay_version <https://www.openssl.org/docs/crypto/SSLeay_version.html>.
By default, the module exports nothing. You can ask for each subroutine bloew to be exported to your namespace.
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.
