I would like to encrypt SP, but I do not know how security different between
1 general procedure with "WITH ENCRYPTION" : display on Object Explorer windows
2 temp procedure with "WITH ENCRYPTION" : NOT display
3 temp procedure without "WITH ENCRYPTION" : NOT display
CREATE PROCEDURE EncryptSP
WITH ENCRYPTION
AS
BEGIN
... Statement ...
END
CREATE PROCEDURE #EncryptSP
WITH ENCRYPTION
AS
BEGIN
... Statement ...
END
CREATE PROCEDURE #EncryptSP
AS
BEGIN
... Statement ...
END
So, I have a question that
1. Is it enough to encrypt with "WITH ENCRYPTION"?
2. Does the temp procedure both encrypt and not encrypt, can decrypt by 3rd party tools?

It's not actually encryption, it's obfuscation. Give me a DB with encrypted procs, I'll give you back the decrypted versions in maybe 10 minutes, if that.

I see, so How can I encrypt the stored procedure?

You can't.
You can encrypt the entire DB with TDE, that's protection against backups been stolen. Otherwise, secure the server, limit access to SQL and make sure you have your permissions set correctly.

The bigger question is what do you hope to gain by encrypting the procedure code? I doubt you are doing anything so revolutionary that you need to protect how you manipulate the data. The sql is not really very important...now the data itself is another story.

A plug for our sponsors:
redgate SQL Prompt can optionally decrypt objects compiled WITH ENCRYPTION for you right within an SSMS Query window. Encrypted objects appear decrypted when you hover over then and click on the quickview to see the definition.
