Secure your connection string with AWS KMS

This post details the process of integrating AWS KMS for encrypting and decrypting sensitive connection strings within an AWS Lambda function. It covers creating a Go-based Lambda function to interact with a PlanetScale database, setting up a customer-managed key in AWS KMS, encrypting the database DSN environment variable, and modifying the Lambda function to decrypt the DSN at runtime before establishing a database connection. It also includes steps for building and deploying the Lambda function.
