Gibberfish, Inc./Gibberfish User Documentation

We recognize that this is not always convenient or appropriate for every user. In this case, please take the time to re-secure any account or service you intend to use for private activities. Change your passphrases in order to lock-out unauthorized users who may have gained access without your knowledge. Wherever possible, enable two-factor authorization. Check for software updates for all your devices, including your phone, and install them.

VIDEO CALLS

The Nextcloud “Talk” app allows you to create and join video calls in your web browser. For best performance on mobile devices, we recommend that you install and use the “Nextcloud Talk” mobile app, which is available from iTunes, Google Play, and F-Droid.

CHAT

The chat system uses the standard XMPP protocol, which will allow you to chat not only with fellow Gibberfish users, but also with anyone else in the world using an XMPP server. Your XMPP address is <your username>@<your gibberfish server>. For example,

FINAL NOTES

We hope you enjoy using Gibberfish. We have worked hard make it a secure and easy-to use platform, as have the many independent contributors to the various open source projects that we have integrated into our service. Special thanks goes to the folks at Nextcloud, without whom our platform would not be possible.

DESKTOP AND MOBILE CLIENTS

Gibberfish works with the Nextcloud desktop and mobile clients to allow you to automatically sync files to and from the server. This is disabled by default as a security measure. If you wish to use these clients, talk to your Administrator about changing the file access rules. If you decide to sync files locally, only do so if you have turned on full-disk encryption for your device. This protects your files if your device is lost, stolen or hacked

While the comic above explains the concept, the Diceware method recommends a passphrase length of 5 or more words for optimal security.

Using Tor is the single best way to guard your online privacy. This is why we use Tor to deploy your Gibberfish server. While it specifically refers to The Onion Router project, Tor has come to encompass a variety of free products and services people can use to safeguard their online activities. We recommend that everyone use the Tor browser to help anonymize their online presence.

Please carefully read the documentation and FAQ that Tor provides about browsing on their network. They have important recommendations for maintaining your privacy. Importantly, using the Tor browser does not guarantee that all your online activities are anonymous.  

As your security needs escalate Tor has other free tools to help. When you evaluate your Threat Model, you may wish to investigate Bridge servers and Tails. Bridge servers allow people to access Tor in countries that block it. Tails is a Linux operating system, complete with commonly used programs, all on a USB stick. It allows extremely private computing.

Good passphrases are extremely important for safeguarding your data. We (and many security experts) recommend creating passwords using the Diceware method. This is the only method of passphrase generation we consider secure. Its easy to do, and it provides ultra-strong passphrases that can defeat even the most resourceful adversaries.
