OpenTofu Secrets & State Encryption: How to Secure Sensitive Infrastructure Data
Infrastructure as Code improves automation, consistency, and collaboration, but it can also expose sensitive information if not managed carefully. Secrets such as database passwords, API keys, cloud credentials, and TLS certificates can unintentionally end up in OpenTofu state files, configuration files, or CI/CD logs. This guide explains the most common ways secrets are exposed in OpenTofu environments, outlines best practices for secure secret management, and demonstrates how to use OpenTofu’s built-in state file encryption feature, introduced in version 1.7, to better protect sensitive data at rest.
