存储过程批量加密,解密.docVIP

--参考: 下面给出了一个存储过程，它的作用是自动将当前数据库的用户存储过程加密。 DECLARE @sp_name nvarchar(400) DECLARE @sp_content nvarchar(2000) DECLARE @asbegin int declare @now datetime select @now = getdate() DECLARE sp_cursor CURSOR FOR SELECT object_name(id) FROM sysobjects WHERE xtype = P AND type = P AND crdate @now AND OBJECTPROPERTY(id, IsMSShipped)=0 OPEN sp_cursor FETCH NEXT FROM sp_cursor INTO @sp_name WHILE @@FETCH_STATUS = 0 BEGIN SELECT @sp_content = text FROM syscomments WHERE id = OBJECT_ID(@sp_name) SELECT @asbegin = PATINDEX ( %AS + char(13) + %, @sp_content) SELECT @sp_content = SUBSTRING(@sp_content, 1, @asbegin - 1) + WITH ENCRYPTION AS + SUBSTRING (@sp_content, @asbegin+2, LEN(@sp_content)) SELECT @sp_name = DROP PROCEDURE [ + @sp_name + ] EXEC sp_executesql @sp_name EXEC sp_executesql @sp_content FETCH NEXT FROM sp_cursor INTO @sp_name END CLOSE sp_cursor DEALLOCATE sp_cursor 该存储过程利用了 sysobjects 和 syscomments 表，并巧妙地修改了原存储过程的 SQL 定义语句，将 AS 修改为了 WITH ENCRYPTION AS，从而达到了加密存储过程的目的。本存储过程在 SQL Server 2000 上通过。 存储过程解密(破解函数,过程,触发器,视图.仅限于SQLSERVER2000) --*/ /*--调用示例: --解密指定存储过程 exec sp_decrypt 存储过程名 --*/ create PROCEDURE sp_decrypt(@objectName varchar(50)) AS begin begin tran declare @objectname1 varchar(100),@orgvarbin varbinary(8000) declare @sql1 nvarchar(4000),@sql2 nvarchar(4000),@sql3 nvarchar(4000),@sql4 nvarchar(4000),@sql5 nvarchar(4000),@sql6 nvarchar(4000),@sql7 nvarchar(4000),@sql8 nvarchar(4000),@sql9 nvarchar(4000),@sql10 nvarchar(4000) DECLARE @OrigSpText1 nvarchar(4000), @OrigSpText2 nvarchar(4000) , @OrigSpText3 nvarchar(4000), @resultsp nvarchar(4000) declare @i int,@status int,@type varchar(10),@parentid int declare @colid int,@n int,@q int,@j int,@k int,@encrypted int,@number int select @type=xtype,@parentid=parent_obj from sysobjects where id=object_id(@ObjectName) create table #temp(number int,colid int,ctext varbinary(8000),encrypted int,status int) insert #temp SELECT number,colid,ctext,encrypted,status FROM syscomments WHERE id = obje
