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.
