This tool is a command-line utility designed to manage sensitive data by encrypting specific values within structured files such as YAML or JSON. By protecting only the sensitive portions of a file while leaving the structure intact, it ensures that configuration files remain readable for version control systems and automated workflows.
The utility provides a secure development workflow by transparently decrypting files into memory for editing and automatically re-encrypting them upon saving, which prevents plaintext secrets from being written to the local disk. It supports a variety of encryption methods, including PGP, age, and integration with cloud-based key management services, allowing teams to choose between local offline security and managed infrastructure providers.
Beyond file-level protection, the tool automates the injection of decrypted secrets directly into the environment of child processes. It uses path-based configuration matching to apply consistent security policies across a project, ensuring that encryption parameters and key selection remain uniform throughout the development lifecycle.
