这是什么有时也被称为作为craptography'，因为它提供的安全，同时在保护什么功能无用的错觉。如果你想要做正确的密码，因为它是非常困难的使用框架类的，推出自己的

This is what is sometimes known as 'craptography', because it provides the illusion of security while being functionally useless in protecting anything. Use the framework classes if you want to do cryptography right, because it's extremely difficult to roll your own.

对于简单的加密/解密（如果这是你所需要的）的DPAPI 的可以是最简单的方法。
