以下是两个完整的代码示例：

• 如何：使用对称（Rijndael）密钥加密和解密数据


• 如何：用Salt加密数据（C＃ /VB.NET）

您还可能会发现 c＃实现AES加密在这里有趣的。

我发现另一个例子简单的加密和解密数据在C＃中，他们只使用通过短语进行解密。 p>

I have an encrypted string from one of our customers.
This string was encrypted using the AES method in Java.

The only thing I have is the key: "xxxxxxxxxxxxxxxxxxxxxxxx" (24 chars) and the encrypted text: "56e84e9f6344826bcfa439cda09e5e96" (32 chars). (This really is the only data I have)

I can't seem to find a method to decrypt this string.

Could anyone provide me with a working example.

Here are two complete code samples for you:

• How To: Encrypt and Decrypt Data Using a Symmetric (Rijndael) Key
• How To: Encrypt Data With Salt (C#/VB.NET)

You might also find c# implementations of AES encryption here on SO interesting.

I found another example Simple encrypting and decrypting data in C# where they use only the Pass Phrase to decrypt.
