Secret Management for Java Applications
Learn how to manage secrets securely in Java apps. This course explores encrypted configuration files, environment variables, Java KeyStore, and platform-specific tools like DPAPI to help avoid common security mistakes.
What you'll learn
Secrets like API tokens, passwords, and encryption keys are often mishandled in Java applications, hardcoded in source code or stored in plain text config files. This leads to severe security risks and real-world breaches. In this course, Secret Management for Java Applications, you’ll learn how to manage secrets in a secure, scalable, and maintainable way. First, you’ll identify common secret-handling mistakes. Then, you’ll explore secure strategies like encrypting configuration files using Jasypt, loading secrets via environment variables, and using Java KeyStore (JKS) for local secure storage. Finally, you’ll understand Windows-specific secret protection using DPAPI, and review enterprise-grade vault options like AWS Secrets Manager or HashiCorp Vault. By the end of the course, you’ll be equipped to securely store and retrieve secrets in any Java-based application and avoid pitfalls that lead to data exposure.
