C＃SHA-1与PHP SHA-1 ...不同的结果？ [英] C# SHA-1 vs. PHP SHA-1...Different Results?

问题描述

我想从一个字符串计算SHA-1散列，但是当我使用PHP的SHA1函数计算字符串我得到的东西比我尝试在C＃中的不同。我需要C＃来计算相同的字符串作为PHP（因为从PHP字符串是由我不​​能修改第三方计算）。我怎样才能获得C＃生成相同的散列为PHP？谢谢！

字符串= [e-mail]

 字符串连接code = SecretKey的电子邮件+;
        UNI codeEncoding UE =新的Uni codeEncoding（）;
        字节[]散列值，MessageBytes = UE.GetBytes（EN code）;
        SHA1Managed SHhash =新SHA1Managed（）;
        字符串strHex =;        散列值= SHhash.ComputeHash（MessageBytes）;
        的foreach（在散列值BYTE B）{
            strHex + =的String.Format（{0：X2}，B）;
        }

  SHA1（）;
 

解决方案

使用ASCIIEncoding，而不是统一codeEncoding。 PHP使用ASCII字符的哈希计算。

I am trying to calculate a SHA-1 Hash from a string, but when I calculate the string using php's sha1 function I get something different than when I try it in C#. I need C# to calculate the same string as PHP (since the string from php is calculated by a 3rd party that I cannot modify). How can I get C# to generate the same hash as PHP? Thanks!!!

String = [e-mail]

C# Code (Generates d32954053ee93985f5c3ca2583145668bb7ade86)

        string encode = secretkey + email;
        UnicodeEncoding UE = new UnicodeEncoding();
        byte[] HashValue, MessageBytes = UE.GetBytes(encode);
        SHA1Managed SHhash = new SHA1Managed();
        string strHex = "";

        HashValue = SHhash.ComputeHash(MessageBytes);
        foreach(byte b in HashValue) {
            strHex += String.Format("{0:x2}", b);
        }

PHP Code (Generates a9410edeaf75222d7b576c1b23ca0a9af0dffa98)

sha1();

解决方案

Use ASCIIEncoding instead of UnicodeEncoding. PHP uses ASCII charset for hash calculations.
