将字符串转换为GUID，将GUID转换为旧字符串。反之亦然 [英] Convert string to GUID and GUID to old string. Vise versa

问题描述

我使用以下代码从字符串创建了guid：

私人Guid GetGuid（字符串输入）

{

MD5CryptoServiceProvider provider = new MD5CryptoServiceProvider（）;

byte [] inputBytes = Encoding.Default.GetBytes（input）;

byte [] hashBytes = provider.ComputeHash（inputBytes）;

Guid hashGuid = new Guid（hashBytes）;

返回hashGuid;

}

假设我给出了输入参数Arvind和得到了像：77f92c53-38af-42f6-8289-fddbd32f228d



现在我想把这个guid77f92c53-38af-42f6-8289-fddbd32f228d转换回我的原始字符串是Arvind。有什么办法吗？

我尝试过的：

I have created guid from a string using below code:
private Guid GetGuid(string input)
{
MD5CryptoServiceProvider provider = new MD5CryptoServiceProvider();
byte[] inputBytes = Encoding.Default.GetBytes(input);
byte[] hashBytes = provider.ComputeHash(inputBytes);
Guid hashGuid = new Guid(hashBytes);
return hashGuid;
}
suppose i given input parameter "Arvind" and got guid like: 77f92c53-38af-42f6-8289-fddbd32f228d

now i want to convert this guid "77f92c53-38af-42f6-8289-fddbd32f228d" back to my original string which is "Arvind" . is there any way?

Thaks,

推荐答案

没有反转哈希操作的方法（从哈希中检索原始字符串）。这是出于意图而且通常是一项要求。



然而，有可能使用蛮力攻击 - 维基百科 [ ^ ]或字典攻击 - 维基百科 [ ^ ]。



欲了解更多信息，只需搜索一些东西比如md5 reverse hash。

There is no way to reverse a hash operation (retrieve the original string from the hash). That is by intention and usually a requirement.

Howewer, it might be possible to retrieve it using a Brute-force attack - Wikipedia[^] or a Dictionary attack - Wikipedia[^].

For more information just search for something like "md5 reverse hash".
