Knowledge of the steps to configure a driver to encrypt fields in a document.
A working, but not production-ready, client application that utilizes automatic Client-Side Field Level Encryption.
Important
Do Not Use this Application In Production
Since this example application stores an encryption key on your application's filesystem, you risk unauthorized access to the key or loss of the key to decrypt your data.
To view a tutorial that demonstrates how to create a production-ready CSFLE-enabled application, see CSFLE Tutorials.
