About
Keybase is a secure messaging and file-sharing platform that uses public key cryptography to ensure all communications remain private and end-to-end encrypted. It supports teams, families, and communities, allowing users to chat, share files, and connect with identities from platforms like Twitter and Reddit. Additional features include exploding messages, encrypted git repositories, and a built-in Stellar cryptocurrency wallet.
Problem
People lack a simple, trustworthy way to communicate and share files with true end-to-end encryption across personal, family, and professional contexts.
For
Individuals, families, teams, and communities who need secure, private communication and file sharing
How it works
Keybase uses public key cryptography and signature chains to encrypt messages and files so that only intended recipients can read them, with identity verification tied to public social profiles.
