I recently found Securstick which encrypts a folder on a USB stick and supports Linux, MacOS and Windows.
The application runs from the USB stick and opens a browser where you type the password to decrypt the contents. Unfortunately the application would not run from my USB disk on Pop!_OS but i found this post and followed the steps from the user GopherBaroque which resolved the issue for me. Just in case the steps are also below:
- Open your terminal
- Determine the UUID of the drives with the command “sudo blkid“
- Create a mount point using the command “sudo mkdir / media / USB-Stick“
- Enter the stick in the fstab with “sudo nano / etc / fstab“
- Expand the fstab file with the following line:
- UUID=3D72-8344 /media/USB-Stick vfat defaults,users,noauto,exec,uid=1000,gid=1000 0 0
- Instead of “3D72-8344” insert the appropriate UUID of the respective stick
Give Securstick a try and be sure to always encrypt your important and sensitive data.
