Cryptomator, a free and open source client-side encryption tool for cloud files, got an update today and with it, some new features like password saving on Linux, and custom mount flags.
Cryptomator is a Java tool to encrypt cloud storage files for services that don't support client-side encryption, which runs on Windows, Mac, Linux, iOS and Android. It works with cloud storage services that synchronize with a local directory, like Dropbox or Google Drive (including using it with Insync).
