openssl:获取openssl版本号

一、代码

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <openssl/opensslv.h>
#include <openssl/crypto.h>

int main() {

	printf("OPENSSL_VERSION_NUMBER:\n\t\t\t0x%x\n", OPENSSL_VERSION_NUMBER);
	printf("OPENSSL_VERSION_TEXT:\n\t\t\t%s\n", OPENSSL_VERSION_TEXT);
#if !defined(OPENSSL_VERSION_NUMBER) || OPENSSL_VERSION_NUMBER < 0x10100000L
	printf("SSLeay:\n\t\t\t0x%x\n", SSLeay());
	printf("SSLeay_version(SSLEAY_VERSION):\n\t\t\t%s\n", SSLeay_version(SSLEAY_VERSION));
	printf("SSLeay_version(SSLEAY_CFLAGS):\n\t\t\t%s\n", SSLeay_version(SSLEAY_CFLAGS));
	printf("SSLeay_version(SSLEAY_BUILT_ON):\n\t\t\t%s\n", SSLeay_version(SSLEAY_BUILT_ON));
	printf("SSLeay_version(SSLEAY_PLATFORM):\n\t\t\t%s\n", SSLeay_version(SSLEAY_PLATFORM));
	printf("SSLeay_version(SSLEAY_DIR):\n\t\t\t%s\n", SSLeay_version(SSLEAY_DIR));
#else
	printf("OpenSSL_version_num:\n\t\t\t0x%x\n", OpenSSL_version_num());
	printf("OpenSSL_version(OPENSSL_VERSION):\n\t\t\t%s\n", OpenSSL_version(OPENSSL_VERSION));
	printf("OpenSSL_version(OPENSSL_CFLAGS):\n\t\t\t%s\n", OpenSSL_version(OPENSSL_CFLAGS));
	printf("OpenSSL_version(OPENSSL_BUILT_ON):\n\t\t\t%s\n", OpenSSL_version(OPENSSL_BUILT_ON));
	printf("OpenSSL_version(OPENSSL_PLATFORM):\n\t\t\t%s\n", OpenSSL_version(OPENSSL_PLATFORM));
	printf("OpenSSL_version(OPENSSL_DIR):\n\t\t\t%s\n", OpenSSL_version(OPENSSL_DIR));
	printf("OpenSSL_version(OPENSSL_ENGINES_DIR):\n\t\t\t%s\n", OpenSSL_version(OPENSSL_ENGINES_DIR));
#endif

    return 0;
}

在 openssl 1.1.0 环境中编译运行：

[test1280@localhost ~]$ gcc -o main main.c -lssl -lcrypto
[test1280@localhost ~]$ ./main
OPENSSL_VERSION_NUMBER:
			0x1010103f

OpenSSL_version(OPENSSL_BUILT_ON):

OpenSSL_version(OPENSSL_ENGINES_DIR):
			ENGINESDIR: "/usr/lib64/engines-1.1"

在 openssl 1.0.1e 环境中编译运行：

[test1280@test1280 ~]$ gcc -o main main.c -lssl -lcrypto 
[test1280@test1280 ~]$ ./main
OPENSSL_VERSION_NUMBER:
			0x1000105f
OPENSSL_VERSION_TEXT:
			OpenSSL 1.0.1e 11 Feb 2013
SSLeay:
			0x1000105f

SSLeay_version(SSLEAY_CFLAGS):

SSLeay_version(SSLEAY_BUILT_ON):

SSLeay_version(SSLEAY_PLATFORM):
			platform: linux-x86_64
SSLeay_version(SSLEAY_DIR):
			OPENSSLDIR: "/etc/pki/tls"

查看man手册：man OPENSSL_VERSION_NUMBER

SSLeay和SSLeay_version在openssl 1.1.0+版本中已经被废弃（deprecated ）。

在 openssl 1.1.0+ 版本中应当使用：

  • OpenSSL_version_num
  • OpenSSL_version

openssl 1.0.2
https://www.openssl.org/docs/man1.0.2//man3/OPENSSL_VERSION_NUMBER.html

openssl 1.1.0
https://www.openssl.org/docs/man1.1.0/man3/OPENSSL_VERSION_NUMBER.html

二、openssl命令

参考：https://linux.die.net/man/1/version

[test1280@localhost ~]$ openssl version

/usr/include/openssl/crypto.h:#  define SSLEAY_VERSION_NUMBER   OPENSSL_VERSION_NUMBER
/usr/include/openssl/opensslconf-x86_64.h:#if OPENSSL_VERSION_NUMBER < 0x10200000L
/usr/include/openssl/opensslv.h:# define OPENSSL_VERSION_NUMBER  0x1010103fL
[test1280@localhost ~]$ grep OPENSSL_VERSION_TEXT /usr/include/openssl/*
/usr/include/openssl/opensslv.h:# define OPENSSL_VERSION_TEXT    "OpenSSL 1.1.1c FIPS  28 May 2019"
