Jun 3, 2001We are planning to store the pin number in a sqlserver table. This column has to be encrypted and stored in the database. As new records are added this column needs to encrypted automatically. Please advise me of any tools.

With SQL Server 2005 encryption:
1. Is it possible to encrypt a column "in place" - or do we always need to create a new varbinary column to hold the encrypted column? Some products (NetLib Encryptionizer) seem to be able to encrypt an existing column in place.
2.If you encrypt an existing column to a new varbinary column, it it customary to then ALTER the table and delete the existing plain-text column?
Thanks...

Column Security - Encryption Suppport?
Apr 17, 2001Hi
There is a very sensitive table that holds a very sensitive field (i.e. a person's salary). I have a requirement to programmatically encrypt it when the value is stored (I can do that quite easily in the VB client app), but there are times when a suitably 'sa' user should be allowed to perform a SELECT of the table and to view the salary field in the clear.
I think a SQL2000 user-defined function can do the job. The catch is that the client is running SQL 7 and he will only upgrade 'over his dead body', or words to that effect.
Appreciate any ideas you can give!
Cheers & TIA

View 4 Replies View RelatedSQL Server Admin 2014 :: Using Column Encryption With Symmetric Keys
Jun 25, 2015I am trying to implement the column encryption on one of the tables, have used the below link as the reference and got stuck at the last step.
[URL] ....
I have completed the following steps so far.
- CREATE MASTER KEY ENCRYPTION BY PASSWORD = ‘myStrongPassword’
- CREATE CERTIFICATE MyCertificateName
WITH SUBJECT = 'A label for this certificate'
- CREATE SYMMETRIC KEY MySymmetricKeyName WITH
IDENTITY_VALUE = 'a fairly secure name',
ALGORITHM = AES_256,
[Code] .....
Example by using the function
EXEC OpenKeys
-- Encrypting
SELECT Encrypt(myColumn) FROM myTable
-- Decrypting
SELECT Decrypt(myColumn) FROM myTable
When I ran the last command :
-- Decrypting
SELECT Decrypt(myColumn) FROM myTable
I get the following error :
Msg 257, Level 16, State 3, Line 2
Implicit conversion from data type nvarchar to varbinary is not allowed. Use the CONVERT function to run this query.
Where will I use the convert function, in decrypt function or in select statement?
SQL Security :: Encryption 2005 - User Defined Function For Encryption And Decryption
Oct 7, 2015I have created two user defined functions for encryption and decryption using passphrase mechanism. When I call encryption function, each time I am getting the different values for the same input. While I searching a particular value, it takes long time to retrieve due to calling decryption function for each row.
best way to encrypt and decrypt using user defined functions.Below is the query which is taking long time.
SELECT ID FROM table WITH (NOLOCK)
WHERE dbo.DecodeFunction(column) = 'value'
When I try to use symetric or asymetric encryption, I am not able to put "OPEN SYMETRIC KEY" code in a function. So, I am using PassPhrase mechanism.
SQL Security :: Enforcing Unique Constraint On A Column Encrypted With Cell Level Encryption?
May 11, 2015I want to enforce a unique constraint on a column which must be encrypted in MSSQL 2005 using Cell Level Encyption (CLE).
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'itsaSECRET!!!3£3£3£!!!'
CREATE CERTIFICATE ERCERT WITH SUBJECT = 'A cert for use by procs'
CREATE SYMMETRIC KEY ERKEY
WITH ALGORITHM = AES_256
ENCRYPTION BY CERTIFICATE ERCERT
[Code] ....
The output makes it obvious why the constraint has 'not' been enforced.

Aug 4, 2000I was wondering if anyone out there knows if it is possible to encrypt a particular field in a table, or encrypt a whole table. The info would remain on my database and not be sent out anywhere, but I just want an extra level of security against anyone who might try to break into the database.

Jul 7, 2005Hello,
I am needing to migrate an Access database to Sql Server
Express. This database will be distributed as part of a
VB 6 application. This database will have some of the
columns encrypted. My understanding is that SQL Server
Express supports encryption. We will need to be able to
run queries on encrypted data like this, with
LastName being an encrypted column in the database.
Select LastName from Account where LastName = 'Smith'
Select LastName from Account where LastName Like 'Sm%'
Update Account Set where LastName = sLastName
Can this be done using SQL Server 2005 Express and VB 6?
Thanks!

AES Encryption
Jan 11, 2008I am using server 2005 running on a windows server 2003 platform. I am trying to do field encryption using symmetric key implemented by the AES algorithm. I created an AES key and apparently it encrypts the data with no problem, however when I try to retrieve the data after decryption the field is always null. I tried using the same process while using the DES or RC2 algorithm and I could both encrypt and decrypt information, however it does not decrypt for any of the AES algorithm i.e. AES_128, AES_192 and AES_256. Attached is a simple query I used to test it.
create symmetric key CCardKeys
with algorithm = aes_192
encryption by password = 'P@s$w0rD'
open symmetric key CCardKeys
decryption by password = 'P@s$w0rD'
declare @Id varchar(50)
set @Id = encryptbykey(key_guid('CCardKeys'),'Test')
select convert(varchar(50),decryptbykey(@Id))
close symmetric key CCardKeys
Is there something I'm missing with AES.
Thanks for taking the time to help me.

Mar 5, 2007I have a user table with Fields:
UID, name, SSN, phone,address. I need to encrypt all the fields except UID. My company recently moved to sql server 2005 and I have to encrypt old data. We do perform query search based on username and SSN
I have very shallow knowledge of encryption and indexes. I did looked at one of the articles on encrypting data on existing application but could not understand the indexing part(:()
Do i have to define new fields with varbinary as datatype(for ssn, name,phone number) ? I am asking this because in the demo only ssn_index has varbinary and the ssn field is still nvarchar?
Any help will be appreciated.
Thanks,

Apr 19, 2007 I am trying to create a encrypted row in my database Everything here worked except that when i run the final query to decrypt the data It just comes up with null for each row. Even if i do a query to show me the rows that are not null It's like it is saying yeah there is data here but I am only going to show you null instead of what I am supposed to decrypt.Here is what I tried from start to finish Create Certificate
