ZKettle

关于

ZKettle is a self-hosted tool designed for sharing sensitive information with robust security. It employs zero-knowledge encryption, ensuring that all encryption and decryption occurs client-side—either in the browser, via the command-line interface, or within an MCP server process. The server never has access to the plaintext secrets or their decryption keys, storing only the encrypted ciphertext. Secrets are self-destructing, expiring after a set number of views or a predefined time limit, enhancing ephemeral data security. This makes it ideal for temporarily sharing passwords, API keys, or other sensitive data without compromising privacy.

主要功能

• Zero-knowledge, client-side encryption (AES-256-GCM)
• Self-destructing secrets based on views or time limits
• Self-hosted deployment options (Docker, Systemd, direct with TLS/reverse proxy)
• CLI, Web viewer, and MCP Server integration for flexible secret management
• Admin API and metrics endpoint for monitoring and control
• 2 GitHub stars

使用案例

• Securely sharing ephemeral sensitive data like passwords or API keys
• Managing temporary secrets for automated scripts or AI agents
• Internal secure communication channels within an organization
