cryfs-automount

CryFS is a cryptographic software for Cloud storage, it allow make encrypted volumes and uploaded to Dropbox, Drive , etc. For more info: https://www.cryfs.org/

This is a basic script to automount CryFS with various file hosting services at the same time. It can mount existing volumes and also create new ones. It automount the volume at every user login (~/.config/autostart/cryfs-"name".desktop).

It's has been tested with Ubuntu 16.04 and Linux Mint 17.3 Rosa (probably it works with Debian/Ubuntu based distributions that use Gnome).

      * Installation:

  • The scrypt has to be installed in /usr/local/bin/

  • If it's not installed, it'll try to install itselft. To installed manually as simple as:

    • sudo cp cryfs-automount /usr/local/bin/

      * Examples:

  • To create a new volume for Dropbox:

    • First we need to install the dropbox client and configured to use ~/.EncryptedDropbox/Dropbox
    • mkdir -p ~/.EncryptedDropbox/Dropbox/ENCRYPTED ~/Dropbox
    • cryfs-automount -v -b ~/.EncryptedDropbox/Dropbox/ENCRYPTED -m ~/Dropbox --new-volume dropbox
    • Type the encryption phrase twice.

  • To mount a existing volume of Mega:

    • Mega client has to be installed and configured to use ~/.MegaEncrypted
    • mkdir -p ~/.MegaEncrypted/ENCRYPTED ~/MEGA
    • cryfs -b ~/.MegaEncrypted/ENCRYPTED -m ~/MEGA mega
    • Type the encryption phrase.
