SQL Server加密存儲(chǔ)過程用到“WITH ENCRYPTION”參數(shù)的時(shí)候，就可以將它加密，這種加密方式是不可逆的，再也不能打開了，嗚嗚～那么我們改怎么樣才能看到原來的代碼而不破壞這個(gè)存儲(chǔ)過程呢？icech在網(wǎng)上找到了兩個(gè)十分十分大牛的人！一個(gè)是j9988，早在2004年就寫了一個(gè)可以破解加密的存儲(chǔ)過程，支持SQL Server 2000非常的好；另一個(gè)是王成輝翻譯老外寫的一個(gè)，竟然可以支持SQL Server 2005版本！
如何加密SQL Server存儲(chǔ)過程？
命令如：
CREATE Procedure 存儲(chǔ)過程名(...) WITH ENCRYPTION AS ...
SQLServer2005里使用with encryption選項(xiàng)創(chuàng)建的存儲(chǔ)過程仍然和sqlserver2000里一樣，都是使用XOR進(jìn)行了的加密。和2000不一樣的是，在2005的系統(tǒng)表syscomments里已經(jīng)查不到加密過的密文了。要查密文必須使用DAC（專用管理員連接）連接到數(shù)據(jù)庫后，在系統(tǒng)表sys.sysobjvalues查詢，該表的列imageval存儲(chǔ)了相應(yīng)的密文。具體可以使用下面的查詢：
SELECT imageval FROM sys.sysobjvalues WHERE objid = object_id(@procedure) AND
valclass = 1 AND subobjid = 1

英文原文：

SQL 2005 still obfuscates object encryption in a similar manner to SQL 2000.
It is simply an XOR of the encrypted bytes against a known sample to dump
out the real unencrypted bytes. The trick is getting to the the encrypted
bytes. In SQL 2005, instead of querying the SYSCOMMENTS view to get the
binary bytes to decrypt, you need to run the following query from the
dedicated admin connection (DAC) to get the bytes to decrypt:
SELECT imageval FROM sys.sysobjvalues WHERE id = object_id(@procedure) AND
valclass = 1 AND subobjid = 1
where @procedure is the name of the object that you want to decrypt. The
table sys.sysobjvalues is one of those new system tables that is normally
hidden. It is actually easier in SQL 2005 because you don't have to string
together 4000 character blocks from SYSCOMMENTS records like you had to do
in SQL 2000. Code to do the XOR on SQL 2000 is well documented on the web.
I'm including my work below.
This is code that I quickly rolled together from my old SQL 2000 decrypt
code. It isn't perfect yet but should get you down the line. It only does
procedures. It actually wraps the ALTER PROCEDURE in a rolled-back
transaction so it shouldn't be too problematic. Then again my local copy of
SQL Server 2005 only starts with the -f flag this morning ;-). Have fun.
