Encrypting Data Across Replication
Feb 7, 2007
We are looking at setting up peer-to-peer transactional replication between two databases. We have a customer requirement to encrypt the SSN in this database. I have configured replication successfully. I have also successfully encrypted the SSN using a symmetric key (with encryption by certificate). What I haven't done yet is set up encryption to work across a replication topology.
What steps would I have to follow in order to be able to encrypt the SSN on one server, replicate it to the subscriber, and then decrypt the SSN on the subscriber? For this scenario, is there a better way to handle encryption other than a symmetric key encrypted by a certificate?

I have an application that has stores sensitive data in an SQL server and I am currently handling this through my ASP.NET application using the encryption classes in C#.
One of the things we would eventually like to be able to do is use other programs (like Microsoft Access) to run advanced Querys on the tables and retrive the data. With the encyption being done in C#/ASP all that would be returned would be the encrypted data.
I wondering if there is a way to build a layer to encrypt/decrypt data at the database level, my searches haven't yeiled to much info (As well as a trip to Borders) as I haven't seen any books that even touch on this.
I don't know a lot about SQL right now (Mainly only MySQL so Stored Procs and all that stuff are really new to me) so I don't know if I would go about it this way or not? (Using a stored procedure)
Can anyone reccommened where I should start to learn about accomplishing this? Books are usually the best help but I'll take any kind of information that can be thrown my way :-)
Thanks!

Hello,I am running Microsoft SQL Server 2000 on a Windows 2000 Sever. I havebeen working with SQL Server, Building ASp WebSites for many years now.I am by no means an expert - nor have I had ANY formal training. So ebarwith me if my questions seem elementary...I have some questions regarding sensitive data and encryption.There is a project that is headed my way were the social security numberis being used as the unique identifier for an account. I have alwaysused as identity column as a unique identifier. What would be the prosand cons of using the SSN as a unique identifier?#1 How do I go about encrypting the number to store in the DB. Is thisdone within SQL Server? Or before the data is inserted?#2 Is it possible to use an encrypted field as a unique identifier?My gut tells me to use the identity column , encrypt the SSN and not useit as any part of an identifier.Thank You for your Help.. Happy New Year!Please Reply to the Newsgroup.*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

Hi,
I have creating a stored procedure in sql server 2005 to encrypt a parameter value that comes from an asp.net page. this value is of type varchar.
Now i have declared a paramater as varbinary to accept this value in the stored procedure. And encrypting it using symmetric key which is encrypted by certificate.
Now when i enter a value into the textbox in asp.net page. it shows
"implicit conversion from varchar to varbinary not possible" pls tell me what is the solution? do i have to convert the value in vb code while accessing the value of the textbox or do i have to convert the value while passing the value when call stored procedure.
pls tell me the solution so that i don't jave to change any coding in vb.
some solution in sql server itselt.
Thank you
Gaurav

CREATE TABLE TabEncr (
id int identity (1,1),
NonEncrField varchar(30),
EncrField varchar(30)
)
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'OurSecretPassword'
CREATE CERTIFICATE my_cert with subject = 'Some Certificate'
CREATE SYMMETRIC KEY my_key with algorithm = triple_des encryption by certificate my_cert
OPEN SYMMETRIC KEY my_key DECRYPTION BY CERTIFICATE my_cert
INSERT INTO TabEncr (NonEncrField,EncrField)
VALUES ('Some Plain Value',encryptbykey(key_guid('my_key'),'Some Plain Value'))
CLOSE SYMMETRIC KEY my_key
OPEN SYMMETRIC KEY my_key DECRYPTION BY CERTIFICATE my_cert
SELECT NonEncrField,CONVERT(VARCHAR(30),DecryptByKey(EncrField))
FROM dbo.TabEncr
CLOSE SYMMETRIC KEY my_key
What is the problem with this code. It works fine , inserting the value encrypted but when i try to decrypt ,it returns a null value. What is missing. I also tried with symmetric key encryption with asymmetric key. Result is same, returns NULL value. I am using SQL 2005
Happy Coding...

I want to encrypt some audio files before inserting them in a SQL server database. I want to use the built in sql server encryption. I found that the encrypt by key function accepts only text (nchar,nvarchar,etc).
I was thinking or reading the audio file's bytes and change them to a string and then insert them in the database. I just wanted to take opinions here. Is there a better way to do this?
thanks in advance

I need to find a way of encrypting and decrypting data from SQL server 2000. I need to do this as transparently as possible, which is why I need to do this if at all possible before my web application encounters the data.I know this is possible without 3rd party applications using SQL server 2005, as I have a working implementation already; however I need to do this with SQL server 2000 as upgrading is not an option. Using a 3rd party product to encrypt/decrypt is also not possible.Any help much appreciated.Matt Rose

Hi,
I have a SSIS project where I am transferring data from DB2 table to SQL Server table. There is a column called REC_ID which I need to encrypt before we store it in SQL Server. Now, SQL Server has buildin encryption functionality and we need to use that as there are views that will decrypt this column and give data to authenticated users.
So, the question is, is there anyway that I can encrypt the column data in my SSIS package using my target SQL server database key and using SQL server encryptbykey function while transferring?
Thanks,
Ujjaval

I support an accounting application that uses SQL as the db engine. One of our clients is asking about encrypting of certain data within the database. The developer does not encrypt the data nor have they any plans to. My question is, can we turn on encryption of a field in one of the data tables that will not require decryption by the accounting application. In other words, if we set encryption at the db level, can the server itself decrypt the data when it's called by the application? Or does the application have to do the decryption?
Thanks in advance and please excuse my ignorance.

Right-clicking "Protocols for MSSQLSERVER" under the Sql 2005 Server Configuration Manager I
find the "Force Encryption" option. Right-clicking the SQL Native Client Configuration, Client Protocols,
I find "Force Protocol Encryption"
I believe these can be used together to force the connection between a client (running the SQLNC client) and a sql 2005 server to be encrypted. In other words, the data "in motion" can be encrypted.
1. Is my understanding correct?
2. Do I need to use a certificate to make this work?
TIA,

Hi,
I have a VB.net app that access a SQL Express database. I have transactional repliaction set up on a SQL 2000 database (the publisher) and a pull subscription from the VB.net app. I use RMO in the VB app to connect to the publisher. My problem is I am getting some strange behaviour as follows
- if I run the app and invoke the pull subscription it works fine. If I then close my app and go back in, I can access my data without any problem
- If I run the app and try to access data in my SQL Express database it works fine. I can then close the app, reopen it and run the pull subscription it works fine
however.......
- if I run the app, invoke the pull subscription (which runs fine), and then try to access data in my local SQL Express database without firstly closing and reopening the app, I get a login error
- if I run the app, try to access data in my local SQL Express database (which works fine), and then try to run the pull subscription I get a "the process cannot acces the file as it is being used by another process" error. In this case I need to restart the SQL Express service to be able to run replication again.
I get exactly the same behaviour when I use the Windows Sync tool (with my app open at the same time) instead of my RMO code to replicate the data.
I am using standard ADO.Net 2 code to access my SQL Express data in the app and closing all connections etc
Any advice appreciated !
Thanks
Ronan

I have been tasked with encrypting an entire database, and I need some assistance.
Everything that I have looked at leads me to believe that the only way to encrypt a whole database is to encrypt each column seperatly. I am completely stumped and could really use some help.
Is it possible to encrypt a whole database? if so, how?
If not, what other options do I have?
Thanks in advance for the help.

I have a bunch of packages that I was working with on a development server and have now moved to a production server. The package protection level was set to DoNotSaveSensative during the development, when I loaded them onto the production server I changed the protection level to EncryptAllWithPassword. I have a few parent packages that call other packages using the execute package task. Since, I now have encrypted packages i had to supply this task with the password, that is where the problem started. The parent package fails when it tries to execute the child package, saying the password was not supplied or it is wrong. I assure you it is not wrong, so is the parent package not storing the password since it was created with no password? Next I created a new parent package and supplied it with a password to call the child package and it works fine. Do I have to recreate all of my parent packages in this way? Is there a way for the parent package to rebuild itself and store the password? Any help would be appreciated.

I am trying to encrypt a column, and then do a select and decrypt the results.
I believe that I am encrypting the data properly, but whenever I try and do a select the column comes back as NULL.
If I do a select without trying to decrypt the column (select * from table) I get the following:
Name | Dept | Encrypted_Info
-----------------------------------------------
scott | it | 0x38383131
If I try and decrypt it I get this
Name | Dept | Encrypted_Info
-----------------------------------------------
scott | it | NULL
This is the query that I put together to create the database, table, DB Master Key, Cert, encrypt the column, and then select and decrypt the result:
create database QA_Encrypted
Go
create table QA_Encrypted.dbo.Enc_Table1
(UserName varchar(50),
Dept varchar(50),
Encrypted_Info varbinary(MAX))
Go
use QA_Encrypted
Go
if not exists (select * from sys.symmetric_keys where symmetric_key_id = 101)
create Master Key encryption by password = 'Pa55w0rd'
Go
Create Certificate QACert
with subject = 'Certificate for Testing'
Go
Create symmetric Key QAEncryptionKey with Algorithm = DES
Encryption by certificate QACert
Go
open symmetric key QAEncryptionKey decryption by certificate QACert
update QA_Encrypted.dbo.Enc_Table1 set Encrypted_Info = EncryptByKey(Key_GUID('QAEncryptionKey'), 'AUTHENTICATOR')
Go
use QA_Encrypted
insert into dbo.enc_table1 values ('scott', 'it', Convert(varbinary,'8811'))
OPEN Symmetric Key QAEncryptionKey
Decryption by CERTIFICATE QACert
select * from dbo.Enc_Table1
Select Username, Dept, Convert(varchar, DecryptByKey(Encrypted_Info)) as "decrypted"
from dbo.Enc_Table1
Any help would be greatly appreciated.
Thanks in advance

Does anyone know where there is a good summary of what you can do to encrypt data going between SQL Server and it's clients, and for that matter any other security things you can do with SQL Server ? I've been asked to write a document on this for someone and quite frankly I've got too much proper work to do...

When we convert an existing app to start encryption and decrypting data as needed, I am required to make changes to atleast 50 stored procs. Within each of these SPs I do:
-- OPEN SYMMETRIC KEY
-- do the ecrypt or decrypt operation
-- CLOSE SYMMETRIC KEY
Is it possible to not use these steps in each of my SP's? i.e, can we generalize the open and close key calls somewhere else? Any tips are greatly appreciated. TIA.

Using DTSRUNUI, we could generate a encrypted command line for executing the pacakge. Now using DTEXECUI, I can get the command line but is there any way in which I can get it in the encryted format??
Thanks.
