在c＃中将24个字符的字符串加密为64个字符？ [英] Encrypt a 24 character string into 64 characters in c#?

问题描述

hi friends ..如何将24个字符的字符串输入加密为64个字符？如果我解密64字符输出我想要相同的24字符输入回来..它是可能请给我解决方案..

hi friends..How to Encrypt a 24 character string input into 64 characters? And if i Decrypt the 64 character output i want the same 24 character input back..It is posible please give me the solution..

推荐答案

这不是真的我们可以回答的一个问题 - 根据您需要的复杂性和安全性，您可以通过多种方式实现这一目标。唯一的问题是固定大小的输出 - 很难预测输出的大小，因为大多数复杂的加密系统产生的块输出通常不是64字节块。



所以从这里开始： Wiki加密 [ ^ ]并使用Google扩展到那里，或解释你想要实现的目标，我们会看看我们是否可以提供帮助 - 它可能是你正在走一条完全错误的大道！例如，如果这是用于密码，那么加密是一个糟糕的想法 - 您应该对数据进行散列，而不管输入大小如何，它总是产生固定大小的输出。

That isn't really a question we can just answer - there are a huge number of ways you could do that, depending on the complexity and security you need. The only problem is the fixed size output - it is difficult to predict the size of the output since most complicated encryption systems generate "block" outputs which aren't normally 64 byte blocks.

So start here: Wiki Encryption[^] and branch out fvrom there using Google, or explain what you are trying to achieve, and we'll see if we can help - it may be that you are going down a completely wrong avenue! For example, if this is for passwords, then encryption is a poor idea - you should be hashing your data instead, which always produces a fixed size output, regardless of the input size.

你可以使用任何类型算法

这真的不难。

• 使用合适的最小块选择加密实现（例如 16 字节）。
• 添加到您的输入 40 'salt'字节，加密所有。

That's really not difficult.

• Choose an encryption implementation using a suitable minimum block (for instance 16 bytes).
• Add to your input 40 'salt' bytes, encrypt it all.
