![]() This document also touches on our plan for organizations, which isn't yet in development. This document describes the cryptographic decisions in the design. The Keybase File system (KBFS) is now in active development and will be our first product launch. Keybase has been designed to make it easy for users to communicate securely without having to worry about the technical details of cryptography. This document describes the local-key security system. Keybase is a secure messaging and file-sharing app for iPhone and Android that uses the public key cryptography system to encrypt data. In general, we are trying to make light use of passphrases, but for certain operations like locking local secret keys, passphrases can be unavoidable. Local Key Storage (LKS)Ī usability requirement of Keybase is that the user only should have to remember one passphrase, and if that passphrase changes on one device, all other devices to immediately reflect that change. Keybase team encrypted file sharing Keybase is a cryptographically secure, popular tool to verify identities, and provide secure groups, files and chats. Up until today, I usually have to copy/paste the contents or use scp to extradite the file. On occasion, I'd like a copy of some of these notes on another device. In addition, I maintain a sprawling notebook on this development vm. This document describes the protocol, but will eventually be public once the protocol is reviewed. Keybase file sharing I do 90 of my development inside a Linux VM and use VSCode + Remote SSH. When users provision new devices, they exchange keys so that the existing device signs the new device into operation, and the new device gets access to some secret data that otherwise would only be available if the user entered her passphrase (which we try to avoid on mobile devices). Get the free app for iOS, Mac, Android, Windows, and Linux. We posted a follow-on public document describing how we use the bitcoin blockchain to enhance security guarantees.Īs we launched per-device secret keys, we posted another document describing the specifics of user signature chains, and how users go about delegating authority to new keys and revoking old keys. Use Keybase for end-to-end encrypted chat messaging, file sharing, and team collaboration. If everything is setup correctly, under /keybase you should see three directories. ![]() You can connect with communities from Twitter, Reddit, and elsewhere. Keybase connects to public identities, too. Keybase works for families, roommates, clubs, and groups of friends, too. ![]() We use public key cryptography to ensure your messages stay private. Once the Keybase File System has been installed you should be able to access your files at /keybase for Mac/Linux and K:\ on Windows. Keybase is secure messaging and file-sharing. This document describes our high-level approach to system security: namely, that Keybase clients take hints and raw data from our server, but mistrust it, and check all of its work. This will give you native file system access to your Keybase secure file share. What I like the most about Keybase is the end-to-end encryption. Here is a collection of documents describing the crypto at play throughout the
