I have an situation I want encrypted data to be able to get through a select statement.

eg:Select Co1,Col2,encrypt(Amount) as Col3,Col4 from PS_TABLE.

We have a people soft application where data needs to be encrypted,it should be available to all other applications thru mere select statement .

I should be able to include create keys,open keys inside a function.This is not possible.Or else I should be able to call a stored procedure inside function.This is also not possible.

Any help appriciated.

Thanks in advance,

Prakash

There is so weird case when i attempt to encrypt a clear text with a SymmetricKey… Anytime when i try to encrypt the “same” data with the “same” SymmetricKey, then encrypted data is resulted diffenet ( different 128bytes of data).. However i can successfully get back the orjinal cleare data, i kindly ask you to the way to get the “same” encrypted when i encrypt the “same” data with the “same” SymmetricKey ? Is that possible ?

IF NOT EXISTS
(SELECT * FROM sys.symmetric_keys WHERE symmetric_key_id = 101)
CREATE MASTER KEY ENCRYPTION BY
PASSWORD = ‘xxxxx password’
GO

CREATE CERTIFICATE PCredit
WITH SUBJECT = ‘Credit Card Numbers’;
GO

CREATE SYMMETRIC KEY CreditCards_Key11
WITH ALGORITHM = AES_256
ENCRYPTION BY CERTIFICATE PCredit;
GO

This is done in development machine.
I usually take sql database backup and restore in QA server to test.

When i did the sql backup I didnot find the certificate and symmetric keys in QA server.

How do I take the back up of the certificte and symmetric keys and restore in QA server.

Thank you.

My client wants to have ssh2 encryption. I can’t find this encryption in allowed list of sql encryption. Can u let me know if there is any way to impliment this in sql.

I have a situation, where I made a script of my original database (along with data) using Database publishing wizard and I ran that script on another computer, but my encryption keys were been scripted.

I even tried backing up the encryption keys and restored the keys to another computer in a similar fashion as told by Asif.S in the comments. But still I am not able to decrypt the data, i get null as the decrypted data. Please help me ASAP.

I search lot of articles but i found a good article from you.
Great Going…

Thanks for the information. There is one more thing that, what if someone wants to change the Algorithm for master key creation ?
When you create a master key it automatically gets created with “T DES”. The syntax of creating a master key is:

CREATE MASTER KEY ENCRYPTION BY PASSWORD = ‘somepassword’

What if someone wants it to be “AES”. Can that be done. I have surfed through various resources but could not find anything.

Thanks and Regards
