Encrypted in C# and decrypted in PHP

[ariki]

Hi all,

I am working on the php program to decrypted the password which is encrypted by C#. However, the codes show below could not work. Any ideas?

C# coding:

private static String password = @"abc";
        private static String saltV = @"123";
        private static String hashAlgorithm = "SHA1";
        private static int passwordIterations = 2;
        private static String iv = @"123456789123456";
        private static int keySize = 256;
 
         public static string Encrypt(string text)
        {
            byte[] ivBytes = Encoding.ASCII.GetBytes(iv);
            byte[] saltBytes = Encoding.ASCII.GetBytes(saltV);
            byte[] textBytes = Encoding.UTF8.GetBytes(text);
 
            PasswordDeriveBytes key = new PasswordDeriveBytes(
                password, saltBytes, hashAlgorithm, passwordIterations);
 
            byte[] keyBytes = key.GetBytes(keySize / 8);
 
            RijndaelManaged symmetricKey = new RijndaelManaged();
            symmetricKey.Mode = CipherMode.CBC;
 
            ICryptoTransform encryptor =symmetricKey.CreateEncryptorkeyBytes, ivBytes);
 
            MemoryStream memoryStream = new MemoryStream();
            CryptoStream cryptoStream = new CryptoStream(memoryStream,  cryptor, CryptoStreamMode.Write);
            cryptoStream.Write(plainTextBytes, 0, plainTextBytes.Length);
            cryptoStream.FlushFinalBlock();
 
            byte[] cipherTextBytes = memoryStream.ToArray();
            memoryStream.Close();
            cryptoStream.Close();
            return Convert.ToBase64String(cipherTextBytes);
        }

PHP coding:

function decrypt($crytedText) {
$key = "abc";
$iv = "123456789123456";
$text = mcrypt_decrypt(MCRYPT_RIJNDAEL_256,$key,$cryptedText, MCRYPT_MODE_CBC, $iv);
echo("<p>".$text);
