Encryption

Mar 5, 2007

I 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,

K

SQL Security :: Encryption 2005 - User Defined Function For Encryption And Decryption

Oct 7, 2015

I 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.

I 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.

I developed a small VB6 application VB6 that get data from SAP sql database

Now they want that the users logon to this small app using the same username & password that they used in SAP

I can read the users' table, I can get the username
But the password is encrypted

Probably with a Function

Anybody know how can I encrypt the typed password so I can compare with the saved password

I don't want to view or modify them, just compare with the password typed by the user

Thanks

Encryption

Jul 7, 2005

Hello,
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, 2008

I 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.

Here is my goal please let me know if it is possible.

I have installed sql express on clients machines. I don't want them to be able to view the sp's or the functions. I would like to go as far as not allowing them to see the tables. I tried with encrption but this is still breakable by the user using the DAC.



Thanks

Encryption With Certificate

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
TestCert
Encryption By Password = 'Password'
With Subject = 'SQLCert',
Expiry_Date = '12/01/2050';


declare @Test nvarchar(50)
set @Test='123456789'

insert into testenc (testencry)
Values
(encryptbyCert(Cert_ID('TestCert'),@Test ))


select convert (Nvarchar(50),
DecryptByCert(Cert_ID('TestCert'),
testencry,N'Password')) As Test
from testenc

DTS Encryption Error .. Bah !

May 29, 2001

Hi,

I have created a DTS package on my SQL 7.0 SP3 server which simply reads a table on another SQL 7.0 server and populates a local table with the information that has been read.

Whenever I try to execute the DTS package (via Run or scheduling it) I get the following error:

-------------------------------------------------------------------------
... DTSRun: Executing... DTSRun OnStart: Delete from Table [AfterSalesAccessories].[dbo].[model_derivative] Step DTSRun OnError: Delete from Table [AfterSalesAccessories].[dbo].[model_derivative] Step, Error = -2147217887 (80040E21) Error string: The property 'Use Encryption for Data' is not supported. Error source: Microsoft Data Transformation Services (DTS) Package
-------------------------------------------------------------------------

I have not selected the encryption option and can't see what I'm doing wrong.
Has anybone else seen this ? I've looked on Technet but no joy.

Thanks,

Tim

In my SQL server 7.0, I have got 250 store procedures in each database.

SQL 2000 Encryption

Jun 12, 2001

Hello all,

I'm have set up sql 2000 in an active/passive cluster setup and I am looking to encrypt the data transfer from my backend DMZ (where the sql boxes reside) to the frontend dmz web servers.

I know there is a "check box" option but it says I need an encyption key to enrypted the data. From what I understand Certificate server 1.0 is not very good and the certificate services in Win2k requires ADS.

Is there another alternative?

Thanks,

Troy
