Chamber
What Chamber is
Chamber is a free, MIT-licensed secrets manager that keeps vault files locally for passwords, API keys, certificates, database credentials, and other sensitive information. It uses SQLite with WAL mode for storage and specifies Argon2id key derivation with ChaCha20-Poly1305 encryption using 256-bit keys and 96-bit nonces. Supported entries also include environment variables, SSH keys, and notes. Users can maintain multiple independent vaults and switch between them. Chamber offers a command-line interface and an interactive terminal interface with search, filtering, and clipboard integration. Its backup features include scheduling, configurable retention, compression, and integrity verification; data can be imported or exported in JSON, CSV, or Chamber Backup format. A REST API supports secret and vault operations with JWT authentication and scoped authorization. The API binds to localhost by default, and HTTPS is recommended for production deployment. The project lists Windows, macOS, and Linux support, with prebuilt binaries for Windows x86_64, macOS x86_64, and Linux x86_64 and ARM64. Exported backup files contain plaintext and require careful handling.
