Sql 2005: Encrypting Data In Motion Between Client And Server
Aug 18, 2006
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?
I used the selfssl.exe tool to generate a certificate on my db server, successfully added to Personal Certificates in MMC, added R/W permissions for the service account to the cert, selected the new certificate in the protocols for mssql and restarted the service. So far so good, however when trying to connect from SSMS with encryption check box checked I get the following error:
A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.) (Microsoft SQL Server, Error: -2146893019)
The certificate chain was issued by an authority that is not trusted.
When I look in MMC, the only intended purpose for the certificate is "Server authentication" and I'm not able to add "Client authentication". Does selfssl.exe not support client authentication?

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?
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 :-)
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!
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.
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
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
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 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?
HI allGurus i am struck up in sql 2005.I am new to sql 2005.I have my serverinstalled on one machine.Now what do i download so that i am able toregister it.Now i want to connect to that machine thru enterprise manager or clientlike we do in sql server 2000 thru query analyzer..Will sql 2005 express help.?Please helpRegards
If I give the user access dbo on 1 of the database, when he logon using SQL Server Management Studio for running query etc, can he only see his database instead of other as well system database?
Is there any best practise in term of setting the SQL client for 2005?
Do I need to install SQL Server 2005 Native client drivers on the servers that contain applications that make connections to the new SS2005 db server? My understanding is that this driver is backward compatible with SS 2000... Can I have both installed on the same server, and then create and ODBC driver for either?
I have SQL Server2005 client in my system,I am able to connect SQL Server 2000,but I am unable to create DTS packages.2005 client not at all showing Local packages icon to create package.

Iam a new bee to sql server.I have Installed sql server 2005 ( trail software ) in my Server.I like to install sql server 2005 clinet in another system. Where can i download sql server 2005 client??
My requirement is , i should access sql server database from my client...
Windows 2003 Server and all client PCs are all on the same network. I installed SQL 2005 std version on windows server 2003 and created a database and tables in it.
I have two users, who want to connect to SQL server 2005 from their PCs (they have windows XP):
These are two things that I need to facilitate:
1) They want to be able to write queries using Query Designer and run from their PCs.
2) I created an MS Access database on my PC, I want to use Access database as a front end to the SQL server database. I will create queries, forms in Access DB, and I want to be able to get the data from SQL server Database to do this. I guess I can use ODBC to connect to tables in SQL server database.
3) I want to connect SQL server to Oracle database, and run oracle stored procedures. I want to load the results of oracle stored procedures into SQL server database tables. I guess I will use IIS for this.
Any suggestions are appreciated, especially with item number 1.
I'm trying to remember how to install the SQL 2000 client tools onto a SQL 2005 server. There are a couple of bizarre steps that will allow this to happen, but I can't for the life of me remember what comes after the unicycle down the stairs with the umbrella stand of machetes.
Can anybody remember the magic, or do I resort to using VPC to kludge the install until I can find my clay tablets again?
Unable to locate client connectivity software ntwdblib.dll Check with your miscrosoft SQL Server database administrator to install the appropriate client software.
Where will find Client software and how do we install that.
I'm having difficulties when connecting to our SQL server 2000 from my SQL Server Mgmt Studio 2005. I can't create tables and columns due to permission errors. But from 2000 (on a different machine) it works fine. *Sometimes* even when I log in with my AD account it won't let me in and complains that user 'null' is not authorized to log in...
Anyway, I've installed both SP1 and SP2 and the problem still persists.
Any help is appreciated.
P.S> I tinstalled SQL 2000 on my machine but that didn't help either; I guess the 2005's configurations are being read by 2000.
Will this work with replication too. I see it with a mirror database, but could it work if I was keeping two copies of the database and wanted to transparently reroute the connection to a surviving server?
When attempting to install SQL Server 2005 SP1, I receive the error, "a recently applied update, KB913090, failed to install." The Installation complete dialog shows the Client Components product Status as "Failure" with the description detail, "Unable to install Windows Installer MSP file". My Operating System is Windows Server 2003 SP1.
I have recently installed SQL 2005 client tools with SQL Server Management Studio and accessing databases on a SQL 2000 server. The response I am getting is extremely slow. Should I go back to SQL 2000 client or are there methods by which I can improve the performance.
I've installed SQL 2005 Express, enabled local and Remote connections but my client app cannot connect to the SQL server. I'm getting access denied or SQL does not exists. Any idea's on how to resolve this issue?
I have installed SQL server 2005 enterprise edition on Windows 2003 virtual PC (full installation). The installation went through successfully. However, after install completed, I cannot find any of the client tools under the start menu -> all programs -> Microsoft SQL server 2005 menu. The only item listed under the SQL server 2005 is Configuration Tools, which is used to configure the database server.
I have tried to install the client component again (in case I didn't install them at the first place) but the installation process cannot be started since it detected that the client components have been installed already. I can also see the sql server native client running in the services.
The server engine is working fine since I can connect to that sql server using another machine where I have the client tool (SQL server management studio).
One of my friends has exactly the same problem. He installed the sql server 2005 Standard edition on windows 2003 server (full installation), but the client tools are not showing up in the start menu either.
I also checked the location for the SQL server management studio (Microsoft SQL server/90/Tools/Binn/VSShell/Common7/IDE), there is only one folder called publicAssemblies listed under. Is this correct or something is missing?
Hello,This is hopefully just a quick question. I'm looking to re-jig our in-house development infrastructure and part of that will be some sort of SQL Server product, and I'm hoping it will be the Developer edition.My question is, how many copies of the Developer edition would I need to purchase, if I have one Windows 2003 server (which will server the databases) and two client machines which will use it.My initial thought is 2 copies, one for each user (as the license states). But what about the server? Do I just install one of the two copies onto the server and the license covers the two client connections?This might seem a silly question with an obvious answer to you guys. However, am I right? I just need to get this clear in my head.Thanks in advance..
What is the ideal method that I can build client/server application by using IIS when I make my programme by using VB2005.net and SQL Server 2005 as database
