SQL Server HASHBYTES SHA2_512和C# [英] SQL Server HASHBYTES SHA2_512 and C#

问题描述

如果我在SQL Server中运行以下命令:

If I run the following in SQL Server:

SELECT HASHBYTES('SHA2_512', 'THE CAT SAT ON THE MAT')

然后在C#中运行它

string test = WordFunctions.SHA512("THE CAT SAT ON THE MAT");

我两者都获得了相同的价值，这很棒.但是，如果我在C#代码中传递一个字符串变量，则如下所示:

I get the same value back for both which is great. However, if I pass a string variable in my C# code so something like this:

string words = "THE CAT SAT ON THE MAT"

byte[] test
test = WordFunctions.SHA512(words);

那我得到的价值不一样吗?！

then I don't get the same value?!

有什么想法吗?

SHA512函数如下所示:

the SHA512 function looks like this:

public static byte[] SHA512(String plaintext)
{
   // convert the passPhrase string into a byte array
   ASCIIEncoding AE = new ASCIIEncoding();
   byte[] passBuff = AE.GetBytes(plaintext);

   SHA512Managed hashVal = new SHA512Managed();
   byte[] passHash = hashVal.ComputeHash(passBuff);

   return passHash;
}

推荐答案

以下代码对我有用:

private static readonly Encoding Encoding1252 = Encoding.GetEncoding(1252);

public static byte[] SHA1HashValue(string s)
{
    byte[] bytes = Encoding1252.GetBytes(s);

    var sha1 = SHA512.Create();
    byte[] hashBytes = sha1.ComputeHash(bytes);

    return hashBytes;
}
