Cryptomator
Cryptomator provides easy-to-use, transparent, client-side encryption for your cloud. It protects your documents from unauthorized access and prying eyes, while you will still be able to view and edit your documents locally. By not requiring any registration or account and performing all encryption locally, it gives you back control over your data and ensures your privacy. Cryptomator is offered for all major platforms (including Android and iOS).
Cryptomator encrypts file contents and names using the widespread industry standard AES. Your passphrase is protected against brute forcing attempts using scrypt. Additionally, directory structures get obfuscated. For more info about the Cryptomator encryption scheme, check out the online documentation.
Cryptomator is a free and open-source software licensed under the GPLv3. This allows anyone to check our code. Thus, it is impossible to introduce backdoors for third parties or to hide vulnerabilities, so you do not need to trust Cryptomator. Also, vendor lock-ins are impossible. Even if we decided to stop development: The source code is already cloned by hundreds of other developers and development can be picked up by others.

Usage
Cryptomator is available as an AppImage which means "one app = one file", which you can download and run on your Linux system while you don't need a package manager and nothing gets changed in your system. Awesome!
AppImages are single-file applications that run on most Linux distributions. Download an application, make it executable, and run! No need to install. No system libraries or system preferences are altered. Most AppImages run on recent versions of Arch Linux, CentOS, Debian, Fedora, openSUSE, Red Hat, Ubuntu, and other common desktop distributions.
Running Cryptomator on Linux without installation
Unlike other applications, AppImages do not need to be installed before they can be used. However, they need to be marked as executable before they can be run. This is a Linux security feature.Behold! AppImages are usually not verified by others. Follow these instructions only if you trust the developer of the software. Use at your own risk!
Download the Cryptomator AppImage and make it executable using your file manager or by entering the following commands in a terminal:
chmod +x ./*.AppImageThen double-click the AppImage in the file manager to open it.
Sandboxing Cryptomator
If you want to restrict what Cryptomator can do on your system, you can run the AppImage in a sandbox like Firejail. This is entirely optional and currently needs to be configured by the user.
Updating Cryptomator
If you would like to update to a new version, simply download the new Cryptomator AppImage.
The Cryptomator AppImage also can be updated using AppImageUpdate. Using this tool, Cryptomator can be updated by downloading only the portions of the AppImage that have actually changed since the last version.
Integrating AppImages into the system
If you would like to have the executable bit set automatically, and would like to see Cryptomator and other AppImages integrated into the system (menus, icons, file type associations, etc.), then you may want to check the optional appimaged daemon.
Note for application authors
Thanks for distributing Cryptomator in the AppImage format for all common Linux distributions. Great! Here are some ideas on how to make it even better.
Pro Tips for further enhancing the Cryptomator AppImage
Thanks for shipping AppStream metainfo inside your AppImage. Please open a pull request on https://github.com/AppImage/appimage.github.io/blob/master/data/Cryptomator if you have changed it and would like to see this page updated accordingly.
