php 解密 Rijndael256-CBC （也有认为是 AES-CBC-256）加密的数据可以使用 phpseclib 库做解密
解密函数:

use phpseclib3\Crypt\Rijndael;

// 需要 composer 安装 "phpseclib/phpseclib": "^3.0"
// Rijndael 解密函数
function rijndael256_decrypt($data, $key, $iv) {
    $rijndael = new Rijndael('cbc');
    $rijndael->setPreferredEngine("PHP");
    $rijndael->setBlockLength(256);
    $rijndael->setKey($key);
    $rijndael->setIV($iv);
    // 需根据加密数据选择是否使用
    $rijndael->disablePadding(); 
    $data = $rijndael->decrypt($data);

    return $data;
}

测试数据:


// 测试函数
function decodeByAes($uid, $str) {
    $data = hex2bin($str);

    $iv = mb_substr($data, 0, 32);
    $key = substr(md5($uid . "xBre2!@348*|AdedFjsDWy01"), 0, 16);

    $data = mb_substr($data, 32);

    $data = rijndael256_decrypt($data, $key, $iv);

    return trim($data);
}

// 测试数据
$uid = "m2Ux0QezsImyNFdtDzYUBWuPf7Ir2AEwJP5l";
$str = "3365616430336134313637303438356562633734666333666136303361343062d9ac29251ae9a36ddb67f8f2ad55eea477239b4d53150feec4a01275d0b1f8b65ffc2f77774eb1203e26050d0f47273b0c35d663da0fa6ddb32b3e0f20cade3204d8f732a74f509c43251c088c523c79c87d02a91cfbc0ca0ff64e8c2e7fb4f6300c584ae84f7de531213747cd3ea50c3f3fa9fc430e784daab2f9777796b0c2";

$data = decodeByAes($uid, $str);
var_dump($data);
