SM3签名

<?php
require __DIR__ . '/vendor/autoload.php';

$sm3 = new \OneSm\Sm3();

// 字符串签名
echo $sm3->sign('abc') . PHP_EOL;
echo $sm3->sign(str_repeat("adfas哈哈哈", 100)) . PHP_EOL;


// 文件签名
echo $sm3->signFile(__FILE__) . PHP_EOL;

SM4加密

<?php
use OneSm\Sm4;
require __DIR__ . '/vendor/autoload.php';

$data = str_repeat('阿斯顿发到付eeee', 160);
$str_len = strlen($data);

// md5 签名
$sign = md5($data);

// 加密key必须为16位
$key = hex2bin(md5(1));
$sm4 = new Sm4($key);

// ECB加密
$d = $sm4->enDataEcb($data);
// 加密后的长度和原数据长度一致
var_dump(strlen($d) === $str_len);

// ECB解密
$d = $sm4->deDataEcb($d);
// 解密后和原数据相等
var_dump(md5($d) === $sign);


// 初始化向量16位
$iv = hex2bin(md5(2));
// CBC加密
$d = $sm4->enDataCbc($data, $iv);
// 加密后的长度和原数据长度一致
var_dump(strlen($d)===$str_len);

// CBC解密
$d = $sm4->deDataCbc($d, $iv);
// 解密后和原数据相等
var_dump(md5($d)===$sign);
