我正在尝试创建一个脚本来创建一些 MVC 用户进行测试，但是，我在生成密码哈希时遇到了问题。

我正在使用HASHBYTE文档中描述的以下 SQL ：

INSERT INTO webpages_Membership([UserId],[CreateDate],[ConfirmationToken],[IsConfirmed],[LastPasswordFailureDate],[PasswordFailuresSinceLastSuccess],[Password],[PasswordChangedDate],[PasswordSalt],[PasswordVerificationToken],[PasswordVerificationTokenExpirationDate]) VALUES(1,'2013-01-01 00:00:00.000',NULL,1,NULL,0,HASHBYTES('SHA1', CONVERT(nvarchar(4000),'!+test123')),'2013-01-01 00:00:00.000','',NULL,NULL);

但是，生成的哈希似乎是二进制的，而不是 Base64 字符串。

我应该如何为测试数据生成哈希？

SQL Server 具有对 BASE64 编码的内置支持。

declare @source varbinary(max)
set @source = hashbytes('sha', '!+test123')

declare @encoded varchar(max)
set @encoded = cast('' as xml).value('xs:base64Binary(sql:variable("@source"))', 'varchar(max)')

但我不确定你会得到你需要的字符串。因为生成的字符串比 Membership 表中的字符串短。例如，在我的会员表中，我可以看到 'ABwa5RUTn98IqJxFaq3MXC2N6dtUT78HAUWuaI3Kl2BIgbBP0IkkVb70FtOYj9ib+A=='密码“123123”的（68 个字符）字符串，但是上面的代码只'YB8YiWZ++uuzO4wSVyg12j8Cf3g='为相同的密码生成（28 个字符）。

您可以通过使用 Base-16（不是 Base-64）并在二进制字符串前面加上 ，在 T-SQL 中向 MSSQL 服务器提供二进制数据0x，如下所示：

INSERT INTO binaryValues ( [SomeBinaryColumn] ) VALUES ( 0xDEADBEEF )

在 C# 中，您可以直接向 a 提供二进制值，SqlParameter或者如果您像这样生成 SQL：

Byte[] hashData = GetHash();
StringBuilder sb = new StringBuilder( hashData.Length * 2 );
sb.Append("0x");
for(int i=0;i<hashData.Length;i++) {
    sb.Append( hashData[i].ToString("x2") );
}
return sb.ToString();
