CryptoCat

Cryptocat is free software with a simple mission: everyone should be able to chat with their friends in privacy.

In an interconnected world where everyone is watching - not just malicious hackers but even the government - privacy and security of your communication is more important than ever.

With Cryptocat, you can rest easy with the knowledge that your messages are secure and encrypted, from sending to receiving.

With Cryptocat, all messages are encrypted by default, and are "Forward Secure," meaning they can't be decrypted even if your keys are stolen. One Cryptocat account across multiple devices will be able to receive your "Forward Secure" messages even when you're offline.

Cryptocat provides users with the ability to share documents, video recordings, photos and other such media.

Cryptocat is cross-platform, available on Windows, Linux, and Mac. Its code is completely open-source and transparent, allowing anyone to review and verify the quality of its security.

• Open source. All Cryptocat software is published transparently.
• Encrypted by default. Every message is encrypted, always.
• Forward secure. Chats are safe even if your keys are stolen.
• Multiple devices. Devices receive messages even when offline.
• File sharing. Securely share files with friends.

To create a Cryptocat account you simply choose a user name (that is not already in use) and a strong password. There is no need to associate your Cryptocat account with an e-mail address or a telephone number.

The Cryptocat's chat server is located in the Bahnhof Bunker, in Sweden.
