PHP实现AES-128-CBC加密+base64_encode

    //AES加密
    public 
    function encrypt($input)
    {
        // 传false相当于base64_encode()编码了一次
        $encode = base64_encode(openssl_encrypt($input, "AES-128-CBC", '525A3106375942FC', false, '0010010000100100'));
        return $encode;
    }


    // 签名
    public
    function doPost($param, $url, $method, $is_big, $phone)
    {
       
        //AES-128-CBC加密
        $content_data = json_encode($param, JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES);
        $AesValue = $this->encrypt($content_data);

        return $AesValue ;
    }




    //AES解密（未验证，仅供参考）
    public function decrypt($input)
    {
        $key = '397e2eb61307109f6e68006ebcb62f98';      

        $decrypted = openssl_decrypt(base64_decode($input), 'AES-256-CBC', $key, OPENSSL_RAW_DATA, '0010010000100100');
        return $decrypted;
    }
