OPENSSL_VERSION_NUMBER, OPENSSL_VERSION_TEXT, OpenSSL_version, OpenSSL_version_num - get OpenSSL version number

#include <openssl/opensslv.h> #define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL #define OPENSSL_VERSION_TEXT “OpenSSL x.y.z xx XXX xxxx” #include <openssl/crypto.h> unsigned long OpenSSL_version_num(); const char *OpenSSL_version(int t);

OPENSSL_VERSION_NUMBER is a numeric release version identifier:

MNNFFPPS: major minor fix patch status

The status nibble has one of the values 0 for development, 1 to e for betas 1 to 14, and f for release.

for example

0x000906000 = 0.9.6 dev 0x000906023 = 0.9.6b beta 3 0x00090605f == 0.9.6e release

Versions prior to 0.9.3 have identifiers < 0x0930. Versions between 0.9.3 and 0.9.5 had a version identifier with this interpretation:

MMNNFFRBB major minor fix final beta/patch

for example

0x000904100 = 0.9.4 release 0x000905000 = 0.9.5 dev

Version 0.9.5a had an interim interpretation that is like the current one, except the patch level got the highest bit set, to keep continuity. The number was therefore 0x0090581f.

OPENSSL_VERSION_TEXT is the text variant of the version number and the release date. For example, OpenSSL 1.0.1a 15 Oct 2015.

OpenSSL_version_num() returns the version number.

OpenSSL_version() returns different strings depending on t:

OPENSSL_VERSION

The text variant of the version number and the release date. For example, OpenSSL 1.0.1a 15 Oct 2015.

OPENSSL_CFLAGS

The compiler flags set for the compilation process in the form compiler: … if available or compiler: information not available otherwise.

OPENSSL_BUILT_ON

The date of the build process in the form built on: … if available or built on: date not available otherwise.

OPENSSL_PLATFORM

The Configure target of the library build in the form platform: … if available or platform: 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_ENGINES_DIR

The ENGINESDIR setting of the library build in the form ENGINESDIR: …“ if available or ENGINESDIR: N/A” otherwise.

For an unknown t, the text not available is returned.

OpenSSL_version_num() returns the version number.

OpenSSL_version() returns requested version strings.
