go-ext-sm2国密PHP扩展密文指定排序、识别ans1编码等功能

news 来源：原创 2024/9/18 1:26:27

go-ext-sm2

介绍

基于go-gmsm静态库编写的SM2椭圆曲线公钥密码算法PHP扩展
相较于openssl-ext-sm2编译更方便
增加了密文指定排序、识别ans1编码等功能

特性：非对称加密

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

软件架构

zend 常规PHP扩展结构

依赖要求

1，包内在lib文件目录下已包含了mac、liunx编译后的gosm2静态库，自动加载对应环境的静态库，可直接编译

2，编译时注意使用make clean时会把编译好的静态库删除

3，如静态库在编译时不可用、请手动编译go-gogmsm库，完成后放到对应环境的目录下地址:https://gitee.com/state-secret-series/go-gmsm.git

安装教程

解压进入openssl-ext-sm2目录

cd go-ext-sm2

phpize

安装编译

make&&make install

修改php.ini

extension="go_sm2.so"

重启php-fpm或者apache

使用说明

全局定义常量

非ans1加密
GO_SM2_MODE_DEFAULT 
结果ans1加密
GO_SM2_MODE_ASN1密文排列顺序
老规则
GO_SM2_ORDER_C1C2C3
新规则
GO_SM2_ORDER_C1C3C2

创建公钥和私钥

$pub_key 取地址 结果为二进制
$pri_key 结果为二进制$key_pair=go_sm2_key_pair();
dump($key_pair);array:3 ["code" => 200"msg" => "Key generation successful!""data" => array:2 ["publicKey" =>二进制"privateKey" =>二进制]
]返回值code int 200 成功 其他状态失败

签名

$msg 信息
$pri_key 私钥 二进制
$mode 签名返回模式 默认 GO_SM2_MODE_DEFAULT
$iv userid 默认为1234567812345678 可不传
返回 GO_SM2_MODE_DEFAULT r,s 拼接的64位2进制
返回 GO_SM2_MODE_ANS1 r,s 编码的30开头的2进制
$sign=go_sm2_sign($msg, $pri_key)array:3 ["code" => 200"msg" => "Key generation successful!""data" => array:1 ["signature" => 二进制]
]
//转成hex16进制$iv='1224222232424333';
$sign=go_sm2_sign($msg,$pri_key,GO_SM2_MODE_ANS1)$sign=go_sm2_sign($msg, $pri_key,GO_SM2_MODE_ANS1,$iv);返回值code int 200 成功 其他状态失败

验签自动识别是否是ans1 无需传mode

$msg 信息
$signature 输入签名结果
$pub_key 公钥 二进制
$iv userid 默认为1234567812345678go_sm2_verify($msg, $pub_key,$signature)；go_sm2_verify($msg, $pub_key,$signature,$iv)；返回值code int 200 成功 其他状态失败

公钥加密

$msg 信息
$encrypt 输出加密结果 二进制 
$pub_key 公钥 二进制
$order 排序方式 默认C1C3C2
$mode  是否ans1编码 默认不编码$encrypt=go_sm2_encrypt($msg, $pub_key);$encrypt=go_sm2_encrypt($msg, $pub_key,GO_SM2_ORDER_C1C2C3);$encrypt=go_sm2_encrypt($msg, $pub_key,GO_SM2_ORDER_C1C2C3,GO_SM2_MODE_ASN1);返回值code int 200 成功 其他状态失败

私钥解密自动识别ans1编码格式的密文

$encrypt 加密信息 二进制
$string 输出结果 明文
$pri_key 私钥
$order 排序方式 默认C1C3C2go_sm2_decrypt($encrypt, $string, $pri_key);
go_sm2_decrypt($encrypt, $string, $pri_key,GO_SM2_ORDER_C1C2C3);返回值code int 200 成功 其他状态失败
