加密在.NET /解密在SQL Server [英] Encrypt In .NET / Decrypt in SQL Server

问题描述

有没有办法从SQL Server查询数据时，一列来解密已经通过.NET使用DES加密（2005/2008）数据库？如果是这样，怎么样？我有钥匙，但不知道如何在SQL Server查询的上下文中使用它。

Is there a way to decrypt a column when querying data from a SQL Server (2005/2008) database that has been encrypted using DES via .NET? If so, how? I have the key, but don't know how to use it within the context of a sql server query.

推荐答案

我可能会考虑的在SQL Server中创建CLR函数来处理这个解密。

I would probably consider creating a CLR function in SQL Server to handle this decryption.

您可以使用此功能，就像任何其他的UDF SQL Server中解密需求。

You can use this function just like any other UDF within SQL Server to decrypt on demand.

这样的话，它的简单，只要使用普通的.NET C＃code来处理它正是你会做你的应用程序本身的方式。

That way, its as simple as using regular .NET C# code to handle it exactly the way you would do it in your application itself.
