KBFS

KBFS stands for Keybase File System. It is a distributed file system that is encrypted and peer-to-peer. KBFS was developed by Keybase, a company focused on identity and security. The system allows users to securely share files and folders with other Keybase users. All data stored in KBFS is end-to-end encrypted, meaning only the intended recipients can access it.

KBFS leverages the public key cryptography infrastructure of Keybase for user authentication and encryption. Files and directories are organized into "folders" that can be shared with specific individuals or teams. Permissions can be set to control read, write, and admin access for each shared folder. The distributed nature of KBFS means that data is not stored on a central server, enhancing privacy and resilience.

When a user creates or adds a file to KBFS, it is encrypted locally before being uploaded and distributed across the network of participating users. This ensures that even the operators of the underlying infrastructure cannot access the content of the files. KBFS is accessible through the Keybase client application, which integrates with the user's operating system. The system aims to provide a secure and user-friendly way to manage and share sensitive information.
