国密算法sm2在php56环境thinkphp32框架下的应用配置

本人在CentOS7 CentOS8 上面使用宝塔面板安装php5.6成功通过

注意 ：

• 需要 gmp 扩展
• 在线生成 sm2公钥私钥对 https://const.net.cn/tool/sm2/genkey/
• 依赖项目 https://github.com/wzhih/guomi
• please make sure you upgrade to Composer 2+

git clone https://gitee.com/liu21st/thinkphp32.git sm2_thinkphp32
composer install
composer require mdanter/ecc:0.4.7
composer require wzhih/guomi

设置 Application/Common/Conf/config.php

<?php
return array(
    // https://const.net.cn/tool/sm2/genkey/ 
    'sm2_privatekey' => '2CF65879B2C8684BBE6C3D3F295C62F9F84AC6C417D028582538A631A3D1AEF1',
    'sm2_publickey' => 'A33337CEA6024821169B0E748FEA46FAE6F2AB65F52D3BE5185E94AB34D7E1EF5A1A4E42C5C386D72AD431DB565D57EE1395E8F1A1B1BCFEDADCC014C02F18C1',
);

设置 Application/Common/Common/function.php

<?php

require_once APP_PATH . '/../vendor/autoload.php';

//
function encrypt_sm2($str, $publickey)
{
    $sm2 = new \Rtgm\sm\RtSm2();
    $m2EncryptData = $sm2 ->doEncrypt($str, $publickey);
    return $m2EncryptData;
}

function decrypt_sm2($m2EncryptData, $privatekey)
{
    $sm2 = new \Rtgm\sm\RtSm2();
    $m2DecryptData = $sm2 ->doDecrypt($m2EncryptData, $privatekey);
    return $m2DecryptData;
}

function sign_sm2($document, $privatekey)
{
    $sm2 = new \Rtgm\sm\RtSm2('base64');
    return $sm2 ->doSign($document, $privatekey);
}

function verify_sign_sm2($document, $sign, $publickey)
{
    $sm2 = new \Rtgm\sm\RtSm2('base64');
    return $sm2 ->verifySign($document, $sign, $publickey);
}

在控制器里面代码

http://localhost/home/index/sm2

<?php
namespace Home\Controller;

use Think\Controller;

class IndexController extends Controller
{

    public function phpinfo()
    {
        echo phpinfo();
        exit();
    }

    public function sm2()
    {
        $privatekey = C('sm2_privatekey');
        $publickey = C('sm2_publickey');
        $str = "你好中国，😁xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"; echo "\n<br/>";
        echo "明文： \n<br/>"; echo $str; echo "\n<br/>";
        $m2EncryptData = encrypt_sm2($str, $publickey);

        echo "m2EncryptData: \n<br/>";
        echo $m2EncryptData; echo "\n<br/>";

        $m2DecryptData = decrypt_sm2($m2EncryptData, $privatekey);

        echo "m2DecryptData: \n<br/>";
        echo $m2DecryptData; echo "\n<br/>";

        echo "do sign: \n<br/>";
        $sign = sign_sm2($str, $privatekey);
        print_r($sign); echo "\n<br/>";

        echo "verify_sign_sm2: \n<br/>";
        var_dump(verify_sign_sm2( $str, $sign, $publickey));
        echo "\n<br/>";
        exit();
    }
}

运行结果

明文：
你好中国，😁xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
