C# SHA-1 与 PHP SHA-1 ...不同的结果?

2022-01-10 00:00:00 cryptography sha1 php c# cryptographic-hash-function

我正在尝试从字符串计算 SHA-1 哈希，但是当我使用 php 的 sha1 函数计算字符串时，我得到的结果与我在 C# 中尝试时不同.我需要 C# 来计算与 PHP 相同的字符串(因为来自 php 的字符串是由我无法修改的第 3 方计算的).如何让 C# 生成与 PHP 相同的哈希?谢谢！！！

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!!!

字符串 = s934kladfklada@a.com

String = s934kladfklada@a.com

sha1();

推荐答案

使用 ASCIIEncoding 而不是 UnicodeEncoding.PHP 使用 ASCII 字符集进行哈希计算.

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