C#中的PHP MCRYPT_RIJNDAEL_128加密

概述我正在尝试用C#重写这个函数.但是C#输出与php不匹配 PHP版本 // Encrypt data using AES128-cbcfunction encrypt($data, $key, $iv) { $cipher = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', 'cbc', ''); mcrypt_generic_init($ 我正在尝试用C#重写这个函数.但是C#输出与PHP不匹配

PHP版本

// Encrypt data using AES128-cbcfunction encrypt($data,$key,$iv) {    $cipher = mcrypt_module_open(MCRYPT_RIJNDAEL_128,'','cbc','');    mcrypt_generic_init($cipher,$iv);    $multipass = mcrypt_generic($cipher,$data);    mcrypt_generic_deinit($cipher);    return $multipass;}

C#版本

public static string encrypt(string encryptionString,string iv,string key){    byte[] clearTextBytes = EnCoding.UTF8.GetBytes(encryptionString);    var rijn = SymmetricAlgorithm.Create();    rijn.KeySize = 128;    rijn.Mode = CipherMode.CBC;    var ms = new MemoryStream();    var cs = new CryptoStream(ms,rijn.CreateEncryptor(EnCoding.UTF8.GetBytes(key),EnCoding.UTF8.GetBytes(iv)),CryptoStreamMode.Write);    cs.Write(clearTextBytes,clearTextBytes.Length);    cs.Close();    var tmp = EnCoding.UTF8.GetString(ms.ToArray());    return tmp;}

解决方法 使用PHP加密/解密：

class Cipher {    private $key,$iv;    function __construct() {        $this->key = "edrtjfjfjlldldld";        $this->iv = "56666852251557009888889955123458";    }    function encrypt($text) {        $block = mcrypt_get_block_size(MCRYPT_RIJNDAEL_256,MCRYPT_MODE_CBC);        $padding = $block - (strlen($text) % $block);        $text .= str_repeat(chr($padding),$padding);        $crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256,$this->key,$text,MCRYPT_MODE_CBC,$this->iv);        return base64_encode($crypttext);    }    function decrypt($input) {        $dectext = mcrypt_decrypt(MCRYPT_RIJNDAEL_256,base64_decode($input),$this->iv);        return $dectext;    }}

使用C#加密/解密：

public class RijndaelSimple    {        const string iv = "56666852251557009888889955123458";        const string key = "edrtjfjfjlldldld";        static public String EncryptRJ256(string plainText)        {            var enCoding = new UTF8EnCoding();            var Key = enCoding.GetBytes(key);            var IV = enCoding.GetBytes(iv);            byte[] encrypted;            using (var rj = new RijndaelManaged())            {                try                {                    rj.padding = paddingMode.PKCS7;                    rj.Mode = CipherMode.CBC;                    rj.KeySize = 256;                    rj.BlockSize = 256;                    rj.Key = Key;                    rj.IV = IV;                    var ms = new MemoryStream();                    using (var cs = new CryptoStream(ms,rj.CreateEncryptor(Key,IV),CryptoStreamMode.Write))                    {                        using (var sr = new StreamWriter(cs))                        {                            sr.Write(plainText);                            sr.Flush();                            cs.FlushFinalBlock();                        }                        encrypted = ms.ToArray();                    }                }                finally                {                    rj.Clear();                }            }            return Convert.ToBase64String(encrypted);        }        static public String DecryptRJ256(string input)        {            byte[] cypher = Convert.FromBase64String(input);            var sRet = "";            var enCoding = new UTF8EnCoding();            var Key = enCoding.GetBytes(key);            var IV = enCoding.GetBytes(iv);            using (var rj = new RijndaelManaged())            {                try                {                    rj.padding = paddingMode.PKCS7;                    rj.Mode = CipherMode.CBC;                    rj.KeySize = 256;                    rj.BlockSize = 256;                    rj.Key = Key;                    rj.IV = IV;                    var ms = new MemoryStream(cypher);                    using (var cs = new CryptoStream(ms,rj.CreateDecryptor(Key,CryptoStreamMode.Read))                    {                        using (var sr = new StreamReader(cs))                        {                            sRet = sr.Readline();                        }                    }                }                finally                {                    rj.Clear();                }            }            return sRet;        }    }
