Cryptocat: Secure End-to-End Encrypted Messaging
Free open source messaging application with end-to-end encryption for secure conversations, available for download or online use
What is Cryptocat?
Cryptocat is a free and open source messaging application designed for secure online chatting. It uses strong encryption to safeguard communications, protecting the privacy of users.
Some key features of Cryptocat include:
- End-to-end encryption - Messages are encrypted on the sender's device and only decrypted on the recipient's device, preventing third parties from accessing conversations.
- Forward secrecy - New encryption keys are generated for each session, so past communications cannot be decrypted even if a key gets compromised in the future.
- Off-the-record messaging - Cryptocat supports OTR messaging which enables ephemeral, self-destructing messages that leave no trace after closing the chat window.
- No logs policy - Cryptocat does not store user conversations on servers, further enhancing privacy.
- Open source - As an open source program, Cryptocat's code is transparent and open to independent security audits.
Cryptocat is available as a browser-based web app for desktop and mobile devices. It offers a simple, accessible way for regular users to gain the security benefits of end-to-end encrypted messaging.
