create proc getinfo
(
@id int
) select *from infotable where id=@id

we can the sp parametres and data type with help of sys tables…but how i can get the sp main script part i.e. select *from infotable where id=@id only???

thanks

i was working on SQL SERVER DBA

i faced one problem from ENCRYPTED STORED PROCEDURES

HOW TO RETRIEVE AND HOW TO READ THE ENCRYPTED STORED PROCEDURE FROM SQL DATABASE

THANK U

I have my StoredProcedure encrypted using “WITH ENCRYPTION”.
Now how can I make changes in this stored procedure.

Reply Soon!!!

Good luck.

Only privileged users who can access system tables over the DAC port or directly access database files as well as can attach a debugger to the server process can retrieve the decrypted procedure from memory at runtime.

Is that mean administrator can view the decrypted procedure? Is there any way to hide or prevent from retrieving the decryted script from the administrator?

I also read on some articles that there are some softwares to decrypt the encrypted SQL scripts. Can we prevent such softwares from decrypting the encrypted SQL scripts?

In user database set the user’s property to remove the View Definition permision on selected or all stored procedures. You can also remove the Execute permission on stored procedures. For this go to database > Security > Users > right click a user > Properties > Securables > here add object and set the permissions on that object.

Did you get any solution for encrypting table structures (not table data)? Please forward me here.

Thanks in Advance.

Yes, Use the code provided above (copyright prevents redistribution so you’ll need to sign up and download the code yourself):

http://education.sqlfarms.com/education/ShowPost.aspx?PostID=783.

and wrap this up in a cursor or loop. You can even call this using xp_cmdshell ‘SQLCMD…’ via a batch file if you wanted to pass in other params (multiple db’s, server\instance, etc).

All the best,

Matt.

Is there anyway of encrypting more than 10 stored procedures at a time?????

Please suggest…….

Thanks in Advance

There is a tool which can decrypt the encrypted stored procedure. Is there any way with which we can restrict decryption of stored procedures? In my situation the database would be in the client side and I would like to enrypt the Stored procedure. Please help.

Thanks,

SQL Server uses the RC4 cipher algorithm to encrypt the procedure text. This algorithm generates a stream of key data (called the keystream) from a starting key, then encrypts the plaintext by using the XOR operation. The beauty of the XOR operation is that to reverse it, you simply XOR the ciphertext with the keystream.

Unfortunately, when you use ALTER PROCEDURE, SQL Server encrypts the new text using the same key as it did when encrypting the original text. This means it uses the same keystream. To recover the keystream when you know the ciphertext and the plaintext, you can simply XOR the ciphertext and plaintext together. You can then recover the original plaintext by XORing the recovered keystream with the original ciphertext.

You can find copies of scripts that do this in numerous places, for example at http://education.sqlfarms.com/education/ShowPost.aspx?PostID=783.

I’m not sure how SQL Server decides what the encryption key should be – it may be as simple as deriving a key from the procedure’s objectid.

SQL Server 2005′s documentation describes the result as ‘obfuscated text’ rather than ‘encrypted’.
