从字符串计算 MD5 hash

[英]Calculate a MD5 hash from a string

 原文  2012-07-12 14:26:02  2   21    c#/ md5

问题描述

I use the following C# code to calculate a MD5 hash from a string.我使用以下 C# 代码从字符串计算 MD5 hash。 It works well and generates a 32-character hex string like this: 900150983cd24fb0d6963f7d28e17f72它运行良好并生成一个 32 个字符的十六进制字符串，如下所示： 900150983cd24fb0d6963f7d28e17f72

string sSourceData;
byte[] tmpSource;
byte[] tmpHash;
sSourceData = "MySourceData";

//Create a byte array from source data.
tmpSource = ASCIIEncoding.ASCII.GetBytes(sSourceData);
tmpHash = new MD5CryptoServiceProvider().ComputeHash(tmpSource);

// and then convert tmpHash to string...

Is there a way to use code like this to generate a 16-character hex string (or 12-character string)?有没有办法使用这样的代码生成 16 个字符的十六进制字符串（或 12 个字符的字符串）？ A 32-character hex string is good but I think it'll be boring for the customer to enter the code!一个 32 个字符的十六进制字符串很好，但我认为客户输入代码会很无聊！

If you are using a version lower than .NET5 this is a neat way to write it如果您使用的版本低于 .NET5，这是一种简洁的编写方式

string.Concat(yourHashBytes.Select(x => x.ToString("X2")))
