I have applied AE on a SQL Server database at column with datatype of numeric(18,0). When I encrypt the data using SSMS the encryption of 154 is
0x01FA3FADE537BB5405E193F859FEDFBBC15C8177AB22F11B139AAB05158F685A29AED638E828BA43457C58668DC05D3DEC8612C28E7221F31BE8E4B291A1408972F186E456038E1041F376370147BCBB54
and I push 154 using JDBC Driver the encryption is
0x01D33F20C4A164160862CDD161305016053C166D4474FD21DA216C353049A8BEFC3EFE177E8FE7CD74E3BC7343D2EC51F7A8DECBD5C31E2F969A0A75D20EFCD7BC4AE0B59708971CF8EAC8C0A450ADA450
I am using a deterministic algorithm.
Because of this I am not able to apply where clause using JDBC. It return only those row which were pushed using JDBC after encryption.
Is there something I can fix to match both the encrypted values?

I enabled Always Encrypted option on a varchar column in database (MS SQL 2019).
Now, ColdFusion (2016) application is generating an error ByteArray objects cannot be converted to strings.
How to enable or register encryption for this database in the CF 2016 server?
UPDATE:
Thanks to Miguel-F comment, I went with this guide below to enable Always Encrypted and configuration of data source in CF Administrator.
https://community.hostek.com/t/sql-server-always-encrypted-columns/315#heading--ColdFusion
But, I stack on the paragraph under the heading
Using Always Encrypted Columns with ColdFusion
....
You must also ensure that the ColdFusion service account has access to the
private key. This service usually runs under the ‘cfusion’ user so you will
want to give read permissions for that user to the private key of the
‘Column Master Key’.
Do I need to create a standard user and login as that user and assign to the service ColdFusion 2016 Application Server? Does this service is reffered here as a "cfusion"?
Then, how would I give that user read permissions for the private key of the ‘Column Master Key’? Is that running certlm?
The column that I encrypted with Always Encrypted option is nvarchar(50), when encrypted, the collation changed to Latin1_General_BIN2.
Still getting this error while open the page with the reference to the column
ByteArray objects cannot be converted to strings.
Any help would be greatly appreciated.

Beginning with SQL Server 2016 (13.x), all algorithms other than AES_128, AES_192, and AES_256 are deprecated. To use older algorithms (not recommended) you must set the database to database compatibility level 120 or lower.

In SSMS I'm connected to an Intersystems Cache database using ODBC driver and linked server When I fetch data using a SQL query like
SELECT Text FROM OPENQUERY([ODBC_CACHE_DB],'SELECT TOP 100 Text FROM cls.Actions')
IN SSMS it gives results but it gives ? for arabic characters like
"18:29:00 [Mohamad] ????? ??? ?? ??? ??? ?????? ????? ? 18:30:30 [Customer] Hi Sirius is jai"
how could get arabic texts ?
note: I can read and write arabic text with using nvarchar data type
Had a similar issue. My setup was a linked server setup between MSSQL 2012 cluster and Intersystems Cache 2009.x using MS OLE ODBC provider.
My observations below:
Convert/Cast on the column with nvarchar datatype did not work -- as in it shows the ???? (This is on SSMS)
When using 3rd Party DB management tools such as Database.net and WinSQL, I was able to see the correct characters.
Playing around with the ODBC driver's Unicode SQL Types function only intermittently helped show the correct characters.
The solution:
Enable Unicode SQL Types function on the ODBC driver
Make changes to the test sql query that is being executed on the Intersystems Cache db. If you keep executing the same query, the output is cached for sometime (not sure how long exactly).
In my case, the sql server cluster was not under my control and took a few days to play around with the different variations.
My name is Hari varma, I am working as a SQL DBA.
Currently I am facing issues with Always Encryption in SQL Server 2017 Development Edition in our testing server.
I don't have any experience in Always Encryption and TDE. One of my client asked me to do encryption on database.
I have done some testing on Always Encryption and I was able to encrypt and decrypt the column data by using doing the following:
On the SQL Server instance
-->Options-->Additional connection Parameter-->Column Encryption Setting = Enabled
After I enabled the column encryption I am able to view the encrypted data in the table.
However I am not able to insert, update, and delete data in this encrypted column.
Also I need to be able to set permissions on users who are allowed / not allowed to view the data on this encrypted column.
Which permissions I need to give on a particular user and provide any prerequisites for Always Encryption and TDE.
First of all it's important to understand that your SQL Server instance does not know the keys used for encrypting and decrypting data when using Always Encrypted. The keys are kept externally, usually in a key store such as Windows Certificate Store or Azure Key Vault. This means that SQL Server itself cannot encrypt or decrypt the data - this instead has to be done by a client application that has access to the keys.
However I am not able to insert, update, and delete data in this encrypted column.
I assume you are attempting to insert, update, and delete data directly through SSMS or something similar. This is only possible to a limited extent. This is because SSMS (which is your client application in this case) needs to be able to encrypt the data before sending it to your SQL Server.
Read more about inserting data into columns that are encrypted via Always Encrypted in SQL Server here (using SSMS).
A brief summary of how to insert encrypted data via SSMS:
You need to enable the column encryption setting in your connection string. This is done under Options>>Additional Connection Parameters when you connect to your SQL Server instance in SSMS. Add this text in there: Column Encryption Setting=Enabled
Once you've connected to your database and opened a query window, you need to enable parameterization for always encrypted. This is done in SSMS under Query>>Query Options>>Execution>>Advanced>>Enable Parameterization for Always Encrypted.
When you've completed the two steps above you'll be able to insert data into an encrypted column like this:
DECLARE #ParameterToBeEncrypted NVARCHAR(100) = 'Decrypt me';
INSERT INTO dbo.MyTable(MyEncryptedColumn) VALUES (#ParameterToBeEncrypted);
This works because your client application (SSMS) is able to encrypt the value that you're initializing #ParameterToBeEncrypted with before sending it to SQL Server. This only works if your current user has access to the column encryption key. SQL Server will never see the plain/non-encrypted value ('Decrypt me') - it will only see the encrypted value that should be inserted into the encrypted column.
Which permissions I need to give on a particular user and provide any prerequisites for Always Encryption
It's a combination of permissions in SQL Server and being able to access the keys used for encrypting and decrypting the data. The necessary database permissions are VIEW ANY COLUMN MASTER KEY DEFINITION and VIEW ANY COLUMN ENCRYPTION KEY DEFINITION.
You can read more about the necessary permissions here.
If you want to encrypt a set of existing data in your database, then your best bet is to write your own client application (e.g. in C# or similar) or create a SSIS package (which would serve as a client application). The client application or SSIS package should read the data from the database, encrypt the data outside of the database, and then send it back to the database as encrypted data.
Previously we have been using sybase with an Adaptive Server Enterprise driver.
Currently we are in the process of switching to MSSQL and will then be using an ODBC Driver 13 for SQL Server.
We keep getting Invalid Descriptor Index errors we didn't get with sybase when calling SQLGetData on an unbound column with index i while the highest bound column has index i+n. This makes sense according to the SQLGetData doc
On the other hand, what isn't making sense to me is that SQLGetInfo with type 81(SQL_GETDATA_EXTENSIONS) returns an empty string for both drivers. I Would expect the sybase one to return something signifying that it has the property SQL_GD_ANY_COLUMN
My question is:
Is there a way to give the ODBC Driver 13 for SQL Server the SQL_GD_ANY_COLUMN property?
If not, how should one then handle text columns of varying lengths(Shouldn't bind those with SQLBind?)?
I'm very new with this so any insight appreciated:)
You cannot change the driver behaviour. I recommend that you make repeated calls to the SQLGetData ODBC function for the text/varchar(max) columns
