加到300分，求在JAVA下的“PBEWithMD5AndDES”加密算法，到C#下如何实现？(三）
加到300分
输入字串：这是一个测试
输出字串：09IdjpQQAPgniEaO/skp9gy8+LkD42fZ
输入字串：123456
输出字串：OEnU8DEcgsE=
以下是JAVA的源代码，想求一下在C#使用哪种函数能实现同样的加密算法。

md5加密
--------------------编程问答--------------------
如果是MD5，就不来劳烦各位了。
这个加密算法是可逆的，从这一点上就可以知道不是MD5了。
不过还是谢谢你的回答。
--------------------编程问答--------------------
身份证加密解密已经解决，请jshi123进来接分。
另密码加密与解密和问题是否也能帮解决一下，我另加100分。谢谢了。
功能是JAVA源码中的“decrypt”函数。
