Migrating Always Encrypted Data

Nitish Upreti shows us how to migrate data encrypted using Always Encrypted:

Our customers use the SQL platform to store volumes of high-valued data assets for their organization. With Always Encrypted, we want to deliver additional security while ensuring complete integrity of stored user data. To achieve this, in a regular workflow SQL Server/Azure SQL Database disallows an application to insert data directly into an encrypted column. If the application has not enabled Always Encrypted in the connection string, an insert statement targeting an encrypted column will fail. To insert a value into a column protected with Always Encrypted, the application must connect to the database with Always Encrypted enabled in the connection string and pass a plaintext value of the datatype configured for the target column. Subsequently, the SQL client driver encrypts the value and sends the ciphertext to the database. This ensures plaintext data is encrypted and stored appropriately.
