Keybase is a user-friendly communication tool that lets you share messages and files with friends, family, and colleagues. It works with a similar interface to popular messaging apps — if you’ve ever used WhatsApp, you’ll find it easy to get connected.
All messages and files sent are securely encrypted, so only you and your recipients can view them. You can store photos, sensitive documents, videos, and more with end-to-end encryption. Plus, if you want to send a secret or sensitive message, you can set a timer to permanently delete (or “explode”) the message.
