Sample Mongoid CSFLE Application

This is a sample application that demonstrates how to use the Mongoid Client-Side Field Level Encryption feature with the Mongoid ODM.

Prerequisites

To use CSFLE with Mongoid, you must have the following:

• A MongoDB Atlas cluster running MongoDB 4.2 or later.
• MongoDB Ruby driver 2.13.0 or later.
• Mongoid 9.0.0 or later. This version is not released yet, so you must use the master branch of the Mongoid repository.
• The crypt_shared library. It can be downloaded from the MongoDB Download Center. Store the library file in vendor/crypt_shared directory.

Getting Started

1. Clone this repository.

2. Install the dependencies:

   bundle install

   Please note that libmongocrypt-helper gem builds the library from sources, so you need to have cmake installed. If you want to avoid building the library, you can download a pre-built version following these instructions. If you decide to do so, you will need to set the LIBMONGOCRYPT_PATH environment variable to the path where you downloaded the library:

   export LIBMONGOCRYPT_PATH=<path to libmongocrypt>

   In this case also remove gem libmongocrypt-helper from the Gemfile.

3. Export the following environment variables :

   export ATLAS_URI=<your MongoDB Atlas connection string>
   export LOCAL_MASTER_KEY=<Random 96-byte string>

4. Create your first data key:

   rails db:mongoid:encryption:create_data_key

5. Export the id of the data key as an environment variable:

   export USER_KEY_ID=<your data key id>

6. Seed the database:

   rails db:seed

7. Run the application:

   rails server

The seeds includes two users: 'jane@doe.com' and 'john@doe.com', both with password '111111'. You can log in with either of them.
