MongoDB – Field Level Encryption

Date: 2023-08-07

This tutorial demonstrates MongoDB's Field Level Encryption (FLE) using Node.js and Docker. FLE encrypts specific document fields, protecting sensitive data even with unauthorized database access. The tutorial covers both deterministic (same plaintext always produces the same ciphertext) and randomized encryption (different ciphertext for the same plaintext). It uses a Docker setup for MongoDB and provides code examples showing connection, data insertion (automatically encrypted), and retrieval (automatically decrypted). While the example uses local key management, the article emphasizes using a robust Key Management System (KMS) in production.
