About:
Blackbox is a version-control friendly system for storing and managing encrypted secrets. It automatically handles GPG encryption and decryption of files, allowing teams to safely store passwords, API keys, and certificates in repositories. The tool integrates with standard VCS workflows like Git and Mercurial, ensuring that only authorized users with the correct keys can access sensitive data.
Key Features:
  • Automatic GPG encryption/decryption of files
  • VCS integration (Git, Mercurial, Subversion)
  • Team key management and access control
  • Support for binary file types
  • Minimal overhead workflow
Use Cases:
  • Storing API keys and credentials in development repositories
  • Sharing encrypted configuration files across development teams
  • Managing production secrets with version control history
Alternatives:
  • git-crypt – Git-specific transparent encryption, while Blackbox supports multiple VCS systems
  • ansible-vault – Ansible-specific encryption, while Blackbox is language/tool agnostic
  • HashiCorp Vault – Full-featured secret management service, while Blackbox is file-based and repository-centric
