SQL Server Database (Field Encryption)
Mar 17, 2000Hi,
Does anyone know how to encrpyt a field in a table created in SQL Server Database.
Hi,
Does anyone know how to encrpyt a field in a table created in SQL Server Database.
Where can I get some information on field-level encryption in SQL Server? My users will be installing my ASP.NET app on a laptop and taking it out "into the field". If it gets stolen they want some safeguards.I've suggested that they encrypt the hard drive and things, but they want field-level encryption for the data. I know how to do things like hash a password, but that doesn't help with retrieval. I have to be able to search on and decode the data. For example, I have SSN as a field. I need to be able to search on SSN, display it to the user, and allow them to change it.The other problem is partial searches. If I encrypt SSN in the database then I can probably just search on the hashed value, but if I want to search on "smith" and get all of the smiths, smithes, etc., then I can't search on the encrypted value. I have about 1 million records, so decrypting each name to do the search would be prohibitive.Anyway, I'm sure this has been done, so if there is a thread or a site that discusses this I'd be willing to read up on it.

What is best way to encrypt password field in sql server 2000?.
Is there any system stored procedure to encrypt password?.
What kind of algorithm password encryption method uses?.
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.
I have created mirroring... one of the column is encrypted on mirror database and I can see the decrypted result when I do query when I actually logged into server (through remote connection) but when I use the same query through using SSMS from my laptop the query result come as the column is not decrypted,

View 1 Replies View RelatedI have code that creates a SQL Mobile database on a server. It has worked in many environments, but I have one customer experiencing an issue. It will not create the database on their server. I would appreciate any thoughts.
The exact error message I get is "the operating system does not support encryption"
I am getting it on the line: SQLCeEngine.CreateDatabase()
Here is the code:
SQLCeEngine = New SqlServerCe.SqlCeEngine(SQLConnectionString)
ReturnValue += ": Declare new"
SQLCeEngine.CreateDatabase()
ReturnValue += ":Create"
SQLCeEngine.Dispose()
ReturnValue += ": Dispose"
Here is the error message I get from our application- the part after Err: is the actual error message from the system:
Data Source = D:EVADATAWebServiceDownloads est;Password=test;Persist Security Info=False;: Declare new:Error!:Err:The operating system does not support encryption.
When I go into SQL Express and create a SQL Mobile database using it, it can be created. So, I have to believe it can be done on the server, but I don't know why the code can not do it.
(e.g. FileConnect Object ExplorerServer Type: SQL Server compact Edition and create a database). The database is successfully created if I do it manually this way. It even creates fine if I select the 'Encrypt' button.
The machine is a Windows 2000 Server sp4 version 5.00.2195
SQL 2000 is installed
SQL 2005 Express is installed
I ran the SQLServerCE31-EN.msi file and it is installed. (I have also re-run and repaired it)
I have also copied over the newest version of our code from scratch.
SQL Server mgmt Studio: 9.00.3042.00
MDAC 2000.085.1128.00
MSXML 2.3 3.1 4.0 5.0 6.0
IE 6.0.2800.1106
.NET Framework 2.0.50727.42
Operating System 5.0.2195
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.
Hi,
i am trying to encrypt my database using dbEncrypt software.The encryption provides role based access ot the database.In that case developer can not call any stored procedure of that database. These two are conflicting things. Can anyone suggest me a way so that i can access the stored procedure through my code by checking the roles from the front end. is it possible??
Please reply soon.

is there a way to encrypt a propriatary database so that it may not betampered with except for those who hold the key?
View 1 Replies View RelatedHello 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
We 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.

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. 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. 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." How I could use my existing key to encrypt the databases or would I have to create a separate key for each db?
View 6 Replies View RelatedI'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?

Hi
Can anyone help?
I have a database using encryption with symmetric keys created using asymmetric keys.
I backed up this database and restored it on another machine along with the service master key.
I can read the encrypted data fine. But all the encrypted stored procs that are associated with the application that uses the data cannot read the data, they just return Nulls.
If I regenerate all the encrypted stored procs from script they work fine again.
Is there a way to restore the database without having to regenerate all the encrypted procs??

Data encryption and database restores.
1. When using data encryption on a 2 node active/passive cluster does it make any difference which server the sqlserver is running on when encrypting or dcrypting data?
2. When restring a database to a different server with encrypted data is the data decrytable or is it lost?
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?

How to limit the length of a database field such that only first 12 characters are shown in the result?
For example, I have show the only first 12 characters of employee name.
I have created an .sdf database on my Desktop - and am able to open and close it just fine from my application program.
Whenever I try to:
Open it with the same program but installed on a different PC,
or:
Open it from a program running as a service on the development PC, I get the error
"The operating system does not support the Encryption Mode provided."
The working above is from the Version 3.5 Beta, but the same problem occurs with Version 3.1.
The Error code in Hex is 80004005
I can't find any reference to fixing this error - any ideas?
I would like to ensure data integrity in a column (actually multiple columns will need a trigger) in my table(s) by setting up a trigger which allows an update of my database field only if the value which is being written to the field in the database exists in another column (in another "check" table).eg. I only want values "Yes", "No" or "" in many of my fields, which I store in a column named "YesNoBlank" in another table.Does anyone know the easy way to do this? / Syntax for the trigger?
