以下是一个基础的例子,通过使用动态 SQL 来模拟解密过程: -- 编写解密函数CREATEFUNCTIONdbo.DecryptStoredProcedure(@ProcNameNVARCHAR(255))RETURNSNVARCHAR(MAX)ASBEGINDECLARE@SQLNVARCHAR(MAX);-- 使用动态 SQL 进行反射获取存储过程的内容SET@SQL=' SELECT OBJECT_DEFINITION(OBJECT_ID('''+@ProcName+''')) '...
步骤1:获取存储过程加密信息 首先,你需要连接到Sql server,并查询存储过程的定义,获取加密后的存储过程信息。 -- 查询存储过程定义SELECTdefinitionFROMsys.sql_modulesWHEREobject_id=OBJECT_ID('YourStoredProcedureName') 1. 2. 3. 4. 步骤2:解密存储过程 接下来,你需要使用DecryptByCert函数对加密后的存储过程...

存储过程加密一般是为了安全需要、或是保护源代码需要而加密存储过程,它一般通过关键字ENCRYPTION 来实现。SQL Server 将 CREATE PROCEDURE 语句的原始文本转换为模糊格式。模糊代码的输出在 SQL Server 2005 的任何目录视图中都不能直接显示。对系统表或数据库文件没有访问权限的用户不能检索模糊文本。但是,可通过 DAC ...

This means extra steps might be necessary to have your SQL Server 2017 (14.x) installation decrypt items that were encrypted by SQL Server 2016 (13.x), as described in Create identical symmetric keys on two servers. For more information, see KB4053407.Applies to: SQL Server 2017 (14.x)...

When a database is first attached or restored to a new instance of SQL Server, a copy of the database master key (encrypted by the service master key) is not yet stored in the server. You must use the OPEN MASTER KEY statement to decrypt the database...
