SQL Server HASHBYTES SHA2_512和C#

Question

如果我在SQL Server中运行以下内容:

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");

我得到了同样的价值,两者都很棒.但是,如果我在C#代码中传递一个字符串变量,那么这样:

string words = "THE CAT SAT ON THE MAT"

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

然后我没有得到相同的价值？!

有任何想法吗？

SHA512函数如下所示:

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;
}

Answer 1

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;
}
