Secure Credential Management for Automated Deployment Pipelines
In modern DevOps environments, automated deployment pipelines are the backbone of continuous delivery. These pipelines often require access to sensitive credentials—API keys, database passwords, SSH keys, cloud provider tokens, and more. Mishandling these secrets can lead to catastrophic security breaches. This post explores a pragmatic approach to credential management using symmetric encryption with Python's cryptography.fernet module, balancing security with operational simplicity.
The Credential Challenge
Hardcoding credentials in pipeline configuration files is an obvious anti-pattern. Equally problematic are:
Storing secrets in environment variables that persist across runs
