I am having the same issue as SSIS: Error from ODBC provider when inserting into Always Encrypted table using CMK in Azure Key Store even with SSIS built in VS 2019 with the ODBC Driver 17 for SQL Server. I am using .netProviders/odbc data driver and getting the following error:


Error: 0xC020844B at Data Flow Task, ADO NET Destination 
[2]: An exception has occurred during data insertion, the message returned from the provider is: 
ERROR [CE269] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]
Error 12038 sending request to https://[****].vault.azure.net:443 

ERROR [CE263] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]
****Error verifying signature of ECEK.**** 

ERROR [CE202] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]
The keystore provider AZURE_KEY_VAULT failed to decrypt the ECEK https://[****].vault.azure.net:443/keys/CMKAuto2/[****...] with RSA_OAEP.

Not sure what I am doing wrong here. My DB is Azure SQL DB. I can view the decrypted data from SSMS and can insert a row as well. But my SSIS data flow is not working.

Can anybody please help me out?
