How To Force Encryption On A Per-database Or Per-user Basis
Oct 30, 2007
I would like to force only certain users on certain databases to use encrypted connections for accessing our 2005 SQL Server. I've found a clunky way to do it, via registering a login event notification and using the kill statement. However, that's ugly, and I don't think there is any guarantee that the event will always fire before an evil client could get off a few evil commands. Is this supported, or is the only supported feature the forceencryption option, which is server-wide?

I want to configure SQL 2k5 Express so that all connections are
encrypted. I've found the documentation that gives the How-To steps,
but I don't see the SSL option in the Network Configuration.
Is this possible with the Express edition?
Do I need to do something special with the installation?
Thanks,
OldSam

I am connection to a SQL server that has force protocol encryption checked. From my ASP.net application, specifically in my connection string, what parameter do I need to use to take advantage of this encryption?
Thanks!

I have a SQL Server 2012 Standard and needed to fulfill a requirement to set Force Encryption on the Server with a DoD Certificate.
I will be altering my client connections to use Encrypt=True; TrustServerCertificate=True (The client is a .Net Web Application).
The OS is where SQL Server 2012 Standard resides is Windows 2008 R2 DataCenter Service Pack 1 64-bit.
What I am needing to know is where do I get the DoD Certificate from? and Do I just install it on the server where SQL Server resides?

Hi,
i've enabled the certification authentication login i use SQL 2K5 ENT
my problem is like that: in the client network utility i check the Force protocol encryption and connect
to the server the client can't connect because he doesn't have the certificate install on his machine which it's OK.
the problem is when i remove the Force protocol encryption on the client he connect successfully without the
certificate install on his machine or any thing.
i double check that on the server i've YES on the Force Encryption in the protocols For MSSQLSERVER.
why is that???
THX

Hi,
I am at a loss here, unless I misunderstand the whole point about server encryption. My 2005 SQL server has a certificate from a trust CA, I have turned on the 'force encryption' flags on the server. My understanding is any client will be "force" to connect with encryption?? I found out that unless I turn on encryption on my clients, the server will allow connections without the requiring encryption. Am I missing something here? Thanks for any help you can provide.

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 have a customer who is looking to encrypt their applications connection to the back-end SQL server. I've gotten a valid certificate for the server from a trusted CA, and it's installed on the server (shows up in Personal certificates in the Certificate MMC when selecting the computer) and I can choose it in the drop down on the certificates tab of the SQL Network protocols properties in Configuration Manager.
Now, my question: If I select the certificate but do NOT enable the "Force Encryption" option, the client will be able to request encryption on their end, and the connection will then be encrypted. If the client (other applications) do NOT request encryption, they will still be able to connect, but their connection will be un-encrypted. URL....
Lastly, I could've swore I had found some information indicating that some methods of establishing a connection to SQL can fail when Force Encryption is enabled, as the method doesn't support SSL encryption.

I am accessing a SQL2005 Express SP1 Server via TCP/IP (all machines fully up to date with windows update). For ease of configuration the Server IP is mapped to an Alias in Native Client Configuration Manager. On the Client Force Protocol Encryption is set to Yes and Trust Server Certificate is set to No. The clients are accessing the DB via SQL 2005 Management studio express and Ms Access 2003 (an access adp front end to the sql database).
As a test i turned off force encryption on the server. A Network trace shows no encryption! Turning on force encryption on the server corrects this.
As a further test I configured the server with a certificate the client doesn't trust. No error is generated by the un-trusted certificate! The only way to generate the certificate error is to enable encryption in the connection properties of each application. Why isn't the Native Client Configuration Manager utility enforcing this???
This brings me on to a second (off-topic problem). In my access adp file, if I enable €œuse encryption for data€? advanced option under the database connection dialog all works as expected (encryption + certificate verification). However, I am programmatically updating the connection in VBA
Application.CurrentProject.OpenConnection "Provider=SQLOLEDB.1;Data Source=AliasName;Use Encryption for Data=True;..."
If I do this no encryption is enabled!!! Access seems to just ignore the encryption statement.
Has anybody got any ideas as to why either of these issues are occurring or if there are any workarounds?
Thanks
Stuart

I have an SSIS package built by another developer, and now that I'm running it under my login the passwords won't save. The solution and packages are setup with ProtectionLevel EncryptSensitiveWithUserKey, but how do I get the User Key to reset so I can now save passwords? I can re-enter them, but whenever I enter hte password and test it then click OK it still has the red arrow next to the connection as if there's an error. I can create new connections and those passwords save fine, but with 40-50 items in this package I hate the thought of having to go into each and change the connection.
I tried changing the package and solution to DontSaveSensitive then rebuilding and closing then reopening, I hoped there was some option to reset the User Key just as if I created the solution. If this option doesn't exist why?

Is there a way to force the modification of a User Defined Function upon which depend other objects.
This is the message:
Msg 3729, Level 16, State 3, Procedure FunctionName, Line 22
Cannot ALTER 'FunctionName' because it is being referenced by object 'OtherObject'.
I have 48 objects related to the function and each time I need modify the function is a big pain.
Any help will be much appreciated.

Hi All,
Anyone have any experience in connecting to a Basis database?
I want to build an SSIS package to ETL data out of a Basis database and into a sql server 2005 db.
I have downloaded the ODBC driver, but am not usre how to plug it in to SSIS to do teh extraction.
Also I am totally new to Basis...it is not an RDBMS at all but the literature says it supports SQL queries, so I am not sure about where to start.
Thanks,
Stephen

Hi,
I'm trying to determine what the best way to do what basically amounts to per user encryption is.
I want to provide the ability for my users to store their passwords (to various applications, and possibly product keys, but the content is mostly irrelevant) in a retrievable format, but I want this information encrypted at rest. I'm not new to cryptography but am fairly new to encryption in sql server.
My issue arises from not seeing how I can manage (creating) the keys for the different users in a fairly automatic fashion.
The closest I've come to what I'd consider to be 'workable' is having the user 'request' access at which point they'd be asked for a password to create their master key. That master key would be used for protecting individual keys for each of the stored items. If so desired it could then continue the key chain to allow users to share specific items. Sadly I don't have the infrastructure for a CA, otherwise I'd go that route as theoretically that should 'just work' if I can assign people certs.
Ideally I'd be assigning users to an active directory security group, which would be part of an 'allowed to use the password tool' server role with appropriate permissions, and the client would authenticate (or be impersonated) through to the database with their pre-existing windows credentials, and everything else would just be magic.
Back on topic, I'm mostly looking for a way to handle this initial key creation (i.e. without a user 'requesting access' and having to create their master key w/password through an interface or support request). I expect I'll have to write an interface for the end user to manage their individual keys and "sharing" regardless of the route I take, so adding a way for them to create the initial key isn't a concern, I'm just worried I may have missed something and will be reinventing the wheel here.
Is there built in functionality I can/should look at regarding this? Or does anyone have a better way to do what I want to?
Thanks for your help.

Hi everybody,
I would like to know if there would be any special way to force drop a database from an ASP.NET page.
When I try to do it in the normal way, it gives me an exception like: Cannot drop the database 'xxxxxxx' because it is currently in use. I'would have to wait until there is a timeout.
In fact that database can be accessed from another pages, but I want to know if I'd be able to force drop database even when another pages are using it.
Thanks in advance

Hello,
I am new to database design and have a very small amount of programming experience, but I am enjoying my project so far. I have a question about SQL database design.
I am creating a VB program that will load a flight data card for an Airforce squadron. One of the items that will end up on the card is the Takeoff and Landing data. Takeoff and landing data is dependent on 4 items for us: power setting, temperature, aircraft weight, and engine type.
I have created 5 tables in my database to store the data: TakoffLandingData, PowerSetting, Temperature, EngineType, and GrossWeight.
I am having some trouble understanding the relationships between these tables. I believe that the PowerSetting, Temperature, EngineType, and GrossWeight tables all have a one-to-many relationship with the TakeoffLandingData table.
However, I am slightly confused by this. For example, for a given gross weight, the airplane will have only one set of takeoff and landing data if the other variables are held contant. However, for one gross weight, the aircraft will have different takeoff and landing data if the engine type is different. Does the EngineType and GrossWeight table then have some sort of relationship I'm missing?
If that's the case it seems like there would be a mess of relationships. I think I'm over-complicating things. Thanks for any assistance you can provide!
Regards,
Nate

I did tried the encryption on server "A" for database "AdventureWorks2012". Then I tried to restore to server "B". There was the certificate issue, and I thought "of course : it's encrypted ! Let's deactivate it". So here I go "ALTER DATABASE AdventureWorks2012 SET ENCYRPTION OFF".I look at sys.databases : not encrypted.I backup using no encryption, I verify using msdb.dbo.backupset : not encrypted.
I move my backup to my other server where encryption was never configured (so no certificate, nothing...), and I have the error :
Msg 33111, Level 16, State 3, Line 1
Cannot find server certificate with thumbprint '0xFA130E58C999C4919B8975999C83A75A403B11D8'.
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.

Hello I just want make sure: There is no encryption of the whole database.I assume this, because I have found only the themes "encryption for connections" and "encrypted columns"Why this question:
A lot of customer ask for this (maybe without further knowledge)
We've got a merge replication with offline laptops.
So, if one of this laptops get lost, it would calm people if the data were encrypted.I'd be very thankful for a fast reply, as my boss is in a meeting with such customers.Kind regardsAline

Hi!
Could you help me how could I encrypt an SQL Express database with a password?
The lines I currently use:
ssconn.ConnectionString = "Data Source=.SQLEXPRESS;Integrated Security=True;"
CreateDatabase = "CREATE DATABASE i ON (NAME = i, FILENAME = '" & ssceconfilename & "')"
Dim myCommand As New SqlCommand(CreateDatabase, ssconn)
myCommand.ExecuteNonQuery()
I intend to encrypt the whole database structure so that nobody could see in.
I managed to do the encryption with SQL CE 2.0, but how to do it with express?
Thank you!

I'm a newbie to SQL and I inherited a 2008 R2 Sql server with about 20 different databases on it. Â I've noticed that more than half of the databases are encrypted and I was looking to encrypt the rest but for some reason I am unable to do so. Â I'm assuming I already have a master key created but when I go to Options of the DB and change Encryption Enabled from False to True I get and error, "Cannot change database encryption state because no database encryption key is set." Â How I could use my existing key to encrypt the databases or would I have to create a separate key for each db?

I'm currently learning how to implement Encryption into my SQL database, and I've run into something I don't know how to explain or understand. I'm working on creating a set encryption for a set of columns in a database, and I don't know how to figure out what size the VARBINARY column needs to be. After some trial and error, I've noticed that a clear text of 9 characters needs 68 varbinary characters, 100 cleartext=148 varbinary, and 254 cleartext= 308 varbinary characters. How is the minimum number of varbinary characters calculated?Â
