PHP sm2 国密扩展

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：https://gitee.com/state-secret-series/openssl-ext-sm2.git

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

1. 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

1. 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

1. 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

1. 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

1. 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);

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。
