About:
Keybase is a security application that provides end-to-end encryption for various services. It enables secure messaging, file storage, and team collaboration by leveraging public-key cryptography. The tool also offers a public directory for mapping identities to cryptographic keys, simplifying the process of establishing trust online.

Key Features:

End-to-end encrypted chat and file sharing
Cryptographic identity proofs for social media and websites
Secure team collaboration with shared directories and key management
Public key directory for easy key discovery

Use Cases:

Securing team communications and file storage
Verifying online identities across different platforms
Encrypting files before uploading to cloud services

Alternatives:

Signal – Focuses primarily on secure messaging, lacks Keybase's file sharing and identity proofing features
ProtonMail – Provides encrypted email, whereas Keybase offers a broader suite including chat, files, and teams
