ZKettle

概要

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.
