在 .NET 中实现强大且简单的加密技术？

我正在研究一个基于 .Net4 和 MVC3 的学生项目。除了一些安全功能（例如用于保存在配置文件（例如连接字符串）中的编码/解码信息）之外，项目几乎已完成。

我想避免非常复杂的解决方案，因此我正在理想地在.NET中寻找一些易于使用的加密技术我只需提供 KEY 和字符串，它就会返回编码文本，反之亦然（类似于下面给出的 Base64 示例）。

我在线浏览了 MSDN 的 System.Security.Cryptography 命名空间文档，但它有我想对于像我这样的新手来说有很多选择。

请向我提供建议和实现这一目标的路径。谢谢。

在搜索时，我发现了一个简单的 Base64 解决方案，我是这样实现的：

    static public string EncodeTo64(string toEncode)
    {
        byte[] toEncodeAsBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(toEncode);
        string encodedValue = System.Convert.ToBase64String(toEncodeAsBytes);
        return encodedValue;
    }

    static public string DecodeFrom64(string toDecode)
    {
        var toDecodeAsString = System.Convert.FromBase64String(toDecode);
        string decodedValue = System.Text.ASCIIEncoding.ASCII.GetString(toDecodeAsString);
        return decodedValue;
    }

工作正常，但问题是据我所知，这不是非常可靠的东西，因为静态编码技术（没有自定义 KEY 的技术）可以轻松解码网上有很多在线 Base 64 解码器。我还尝试使用AES，如此处所述但没能成功。

I am working over one my student project over .Net4 and MVC3.
Project is almost at completion except some security features such as Encoding/Decoding information for saving in config file such as Connection String etc.

I want to avoid a very complex solution and so I am looking for some easy to use Encryption technique in .NET ideally something where I can just provide a KEY and String and it gives me back the encoded text and vice versa (similar to the Base64 example given below).

I went through MSDN’s System.Security.Cryptography Namespace documentation online but it has a lot of options for a newbie like me I guess.

Kindly provide me with suggestions and path to follow to achieve it.
Thank you.

While searching I found a simple solution of Base64 which I implemented like this:

    static public string EncodeTo64(string toEncode)
    {
        byte[] toEncodeAsBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(toEncode);
        string encodedValue = System.Convert.ToBase64String(toEncodeAsBytes);
        return encodedValue;
    }

    static public string DecodeFrom64(string toDecode)
    {
        var toDecodeAsString = System.Convert.FromBase64String(toDecode);
        string decodedValue = System.Text.ASCIIEncoding.ASCII.GetString(toDecodeAsString);
        return decodedValue;
    }

Works fine but the problem is as far as I’ve understood this is not something very reliable as a static encoding technique (one without a custom KEY) can be easily decoded and so many online base 64 decoders are available on net. I also tried to work with AES as expalined here but failed to succeed.
