Keybase is a secure messaging and file-sharing platform that emphasizes encryption and privacy. Keybase allows users to communicate securely through end-to-end encrypted messages, ensuring that only the intended recipients can read the content.

The platform integrates various social media and identity verification methods, enabling users to link their Keybase profile with their Twitter, GitHub, and other accounts. This feature helps verify the authenticity of users, making it easier to establish trust within the Keybase community.

Keybase also offers encrypted file storage and sharing through its Keybase Filesystem (KBFS), which allows users to store, share, and collaborate on files securely. The files are encrypted before they are uploaded, ensuring that only authorized users can access them.

In addition to its robust security features, Keybase supports group chats, encrypted Git repositories, and even cryptocurrency wallets. Its comprehensive suite of tools makes it a versatile platform for individuals and teams seeking secure communication and collaboration solutions.

In 2020, Keybase was acquired by Zoom Video Communications, which has integrated some of its encryption technologies to enhance Zoom's security features. Despite the acquisition, Keybase continues to operate as a standalone service, providing strong encryption and privacy to its users.
