C＃（加密）和Java（解密）之間的AES加密/解密

我有一個C＃應用程序來調用Java Web服務來驗證用戶的密碼。我想讓C＃應用程序加密密碼，然後讓Java Web服務解密密碼。我已經完成了Java方面的代碼（解密代碼），但我無法弄清楚C＃代碼來加密代碼。C＃（加密）和Java（解密）之間的AES加密/解密

這是我的Java代碼...

public void validateUserPassword(String encryptedPassword) { 
    String algorithm = "AES"; 
    SecretKeySpec keySpec = null; 
    byte[] key = "<==OMGWTFBBQ!==>".getBytes(); 

    Cipher cipher = null; 

    cipher = Cipher.getInstance(algorithm); 
    keySpec = new SecretKeySpec(key, algorithm); 

    byte[] encryptionBytes = new sun.misc.BASE64Decoder().decodeBuffer(encryptedPassword);  
    cipher.init(Cipher.DECRYPT_MODE, keySpec); 
    byte[] recoveredBytes = cipher.doFinal(encryptionBytes); 
    String recovered = new String(recoveredBytes); 

    log.info("Encrypted password: " + encryptedPassword); 
    log.info("Dencrypted password: " + recovered); 
}

這裏是我發現使用C＃進行加密，但由於我的Java功能，所以我的Java Web服務是無法也不會產生相同的encrypion串解密它。

private void btnEncrypt_Click(object sender, EventArgs e) 
{ 
    string PlainText = "testing"; 
    string Password = "<==OMGWTFBBQ!==>"; 
    string Salt = "Kosher"; 
    string HashAlgorithm = "SHA1"; 
    int PasswordIterations = 2; 
    string InitialVector = "OFRna73m*aze01xY"; 
    int KeySize = 256; 
    string encryptedPassword; 

    byte[] InitialVectorBytes = Encoding.ASCII.GetBytes(InitialVector); 
    byte[] SaltValueBytes = Encoding.ASCII.GetBytes(Salt); 
    byte[] PlainTextBytes = Encoding.UTF8.GetBytes(PlainText); 

    PasswordDeriveBytes DerivedPassword = new PasswordDeriveBytes(Password, SaltValueBytes, HashAlgorithm, PasswordIterations); 

    byte[] KeyBytes = DerivedPassword.GetBytes(KeySize/8); 
    RijndaelManaged SymmetricKey = new RijndaelManaged(); 
    SymmetricKey.Mode = CipherMode.CBC; 
    byte[] CipherTextBytes = null; 

    using (ICryptoTransform Encryptor = SymmetricKey.CreateEncryptor(KeyBytes, InitialVectorBytes)) 
    { 
     using (MemoryStream MemStream = new MemoryStream()) 
     { 
      using (CryptoStream CryptoStream = new CryptoStream(MemStream, Encryptor, CryptoStreamMode.Write)) 
      { 
       CryptoStream.Write(PlainTextBytes, 0, PlainTextBytes.Length); 
       CryptoStream.FlushFinalBlock(); 
       CipherTextBytes = MemStream.ToArray(); 
       MemStream.Close(); 
       CryptoStream.Close(); 
      } 
     } 
    } 
    SymmetricKey.Clear(); 
    encryptedPassword = Convert.ToBase64String(CipherTextBytes); 

    MessageBox.Show("Encrypted password: " + encryptedPassword); 
}

我不介意改變我的Java Web服務解密的方式，以使其與我的C＃應用程序一起工作。
