使用.NET加密和解密数字 [英] Encrypting and Decrypting Numbers with .NET

问题描述

什么是.NET可用的加密技术（使用C＃）。我有一个数字值我想加密一个字符串表示。哪一个具有解密支持？

What are Encryption techniques available with .NET (using C#). I have a numeric value with me which I want to encrypt to a string representation. Which one has decrypting support ?

推荐答案

加密（由.NET框架/ BCL提供，而不是C＃语言）工作在字节。但是没关系数字很​​容易表示为字节，输出字节可以通过 Convert.ToBase64String 写入字符串。

Encryption (which is provided by the .NET framework / BCL, not C# the language) typically works on bytes. But that is fine; numbers are easy to represent as bytes, and the output bytes can be written as a string via Convert.ToBase64String.

所以所有这些，间接地...

So "all of them, indirectly"...

请参阅 MSDN上的System.Security.Cryptography

（重新解密：加密可以被解密;一个哈希不能（希望）;所以只要你不看哈希函数，你应该罚款）

(re decrypting: an encryption can be decrypted; a hash cannot (hopefully); so as long as you don't look at hashing functions, you should be fine)
