openssl-ext-sm2

介绍

基于openssl密码库编写的SM2椭圆曲线公钥密码算法PHP扩展

特性：非对称加密

git地址：gitee.com/state-secret-series/open...

软件架构

zend 常规PHP扩展结构

依赖要求

1，liunx :openssl/lib必须包含 libcrypto.so和libssl.so 动态库

2，mac :openssl/lib必须包含 libcrypto.dylib和libssl.dylib 动态库

例：liunx

例：mac

安装教程

解压进入openssl-ext-sm2目录

cd openssl-ext-sm2-master

phpize

creating libtool
appending configuration tag "CXX" to libtool
configure: creating ./config.status
config.status: creating config.h
config.status: config.h is unchanged

安装编译

make&&make install

修改php.ini

extension="sm2.so"

重启php-fpm或者apache

使用说明

1. 创建公钥和私钥

$pub_key 取地址 结果为二进制
$pri_key 取地址 结果为二进制

sm2_key_pair($pub_key, $pri_key);

返回值int 0 成功 其他状态失败

2. 签名

$msg 信息
$signature 输出签名结果
$pri_key 私钥 二进制
$iv userid 没有设置默认为空的操作：如需为空请设置1234567812345678

sm2_sign($msg, $signature, $pri_key, $iv)

返回值int 0 成功 其他状态失败

3. 验签

$msg 信息
$signature 输入签名结果
$pub_key 公钥 二进制
$iv userid 没有设置默认为空的操作：如需为空请设置1234567812345678

sm2_sign_verify($msg, $signature, $pub_key, $iv)；

返回值int 0 成功 其他状态失败

4. 公钥加密

$msg 信息
$encrypt 输出加密结果 二进制 
$pub_key 公钥 二进制
sm2_encrypt($msg, $encrypt, $pub_key)

返回值int 0 成功 其他状态失败

5. 私钥解密

$encrypt 加密信息 二进制
$string 输出结果 明文
$pri_key 私钥
sm2_decrypt($encrypt, $string, $pri_key)

返回值int 0 成功 其他状态失败

6. 演示

 $msg = '这是测试';
 $iv = '1234567812345678'; //没有设置默认为空的操作：如需为空请设置1234567812345678

 sm2_key_pair($pub_key, $pri_key);
 base64_encode($pub_key); 
 base64_encode($pri_key); 
 #公钥:BHSAPGXtrHNxqJ3/b0+eNu2mdO0mpDfTGNJUMoEWpNpSL53Dw+YM/B/QT5OoLm4xQtw0hZY5wlWTR+cD629Grek=
 #私钥:++BuzKd1mPa0RXAJcY6DHDq9SUzo3T6/engbKReQRqI=

 sm2_sign($msg, $signature, $pri_key, $iv); 
 base64_encode($signature);  
 #私钥签名:+YHNtKkXbsRSs2nk5amd/YNqsiH8Kyr+oyLVVzuvRl+lqb40uzPxjsRo9QTYw7kZdWSfvM5lbxDMfF0cugQNfQ==

性能测试

纯php代码实现国密算法：博客：国密招商银行对接

服务器参数

物理cpu：2个
逻辑cpu：8个
cpu核数：4个
运行内存：8G

使用php框架：lumen

性能分析

关于执行次数：1000/100次是因为使用纯php服务器跑不了10000次。
