.SH SUMMARY
.IX Header "SUMMARY"
Exposes information provided by SSLeay_version <https://www.openssl.org/docs/crypto/SSLeay_version.html>.
.SH EXPORTS
.IX Header "EXPORTS"
By default, the module exports nothing. You can ask for each subroutine bloew to be exported to your namespace.
.SH SUBROUTINES
.IX Header "SUBROUTINES"
.SS openssl_built_on
.IX Subsection "openssl_built_on"
The date of the build process in the form "built on: ..." if available or ``built on: date not available'' otherwise.
.SS openssl_cflags
.IX Subsection "openssl_cflags"
The compiler flags set for the compilation process in the form "compiler: ..." if available or "compiler: information not available" otherwise.
.SS openssl_dir
.IX Subsection "openssl_dir"
The \f(CW\*(C`OPENSSLDIR\*(C'\fR setting of the library build in the form "OPENSSLDIR: ..." if available or "OPENSSLDIR: N/A" otherwise.
.SS openssl_platform
.IX Subsection "openssl_platform"
The "Configure" target of the library build in the form "platform: ..." if available or "platform: information not available" otherwise.
.SS openssl_version
.IX Subsection "openssl_version"
The version of the OpenSSL library including the release date.
.SS openssl_version_number
.IX Subsection "openssl_version_number"
The value of the \f(CW\*(C`OPENSSL_VERSION_NUMBER\*(C'\fR macro as an unsigned integer. This value is more like a string as version information is packed into specific nibbles see \f(CW\*(C`crypto/opensslv.h\*(C'\fR in the OpenSSL source and <https://metacpan.org/pod/OpenSSL::Versions|OpenSSL::Versions> for explanation.
