Queryable Encryption gives you the ability to perform the following tasks:

  • Encrypt sensitive data fields from the client-side.

  • Store sensitive data fields as fully randomized encrypted data on the database server-side.

  • Run expressive queries on the encrypted data.

These tasks are all completed without the server having knowledge of the data it's processing.

Sensitive data is encrypted throughout its lifecycle - in-transit, at-rest, in-use, in logs, and backups - and only ever decrypted on the client-side, since only you have access to the encryption keys.

Queryable Encryption introduces an industry-first fast, searchable encryption scheme developed by the pioneers in encrypted search. The feature supports equality searches, with additional query types such as range, prefix, suffix, and substring planned for future releases.

You can set up Queryable Encryption using the following mechanisms:

  • Automatic Encryption: Enables you to perform encrypted read and write operations without you having to write code to specify how to encrypt fields.

  • Explicit Encryption: Enables you to perform encrypted read and write operations through your MongoDB driver's encryption library. You must specify the logic for encryption with this library throughout your application.

The following table shows which MongoDB server products support which CSFLE mechanisms:
