Queryable Encryption with the MongoDB EF Core Provider

MongoDB's Queryable Encryption enables encrypting sensitive database fields while maintaining search capabilities through equality and range queries. This tutorial demonstrates implementing queryable encryption using the MongoDB EF Core Provider, covering key management setup (Customer Master Keys and Data Encryption Keys), automatic encryption configuration with crypt_shared library, and field-level encryption configuration through EF Core's fluent API. The guide includes practical examples of encrypting employee data like tax IDs and salaries, querying encrypted fields transparently, and discusses supported data types, limitations, and production deployment considerations including key rotation and secure key management systems.
