Cryptocat is not a magic bullet. Even though Cryptocat provides useful encryption, you should never trust any piece of software with your life, and Cryptocat is no exception. See more
  • Cryptocat does not anonymize you: While your communications are encrypted, your identity can still be traced since Cryptocat does not mask your IP address. For anonymization, we highly recommend using Tor.
  • Cryptocat does not protect against key loggers: Your messages are encrypted as they go through the wire, but that doesn't mean that your keyboard is necessarily safe. Cryptocat does not protect against hardware or software key loggers which might be snooping on your keyboard strokes and sending them to an undesired third party.
  • Cryptocat does not protect against untrustworthy people: Parties you're conversing with may still leak your messages without your knowledge. Cryptocat aims to make sure that only the parties you're talking to get your messages, but that doesn't mean these parties are necessarily trustworthy.
