Hello!

Can anyone advice really good encryption tool for Linux Mint? For example to create encrypted container directly on Linux?

I am searching for tool that follows this criteria:

  • no proprietary or paid.
  • completely open source, better if audited
  • works on Linux (I don’t need other OS)
  • secure.

I will be happy if you help me!

Have you considered using Linux’s built-in encryption with LUKS/dm-crypt? It’s widely used for creating encrypted containers on Linux and meets your criteria: open source, audited and Linux-native.

You can create a file container and then use cryptsetup to format it with LUKS. Once set up, you can open the container with a passphrase and mount it as needed. It’s very secure.

For a bit more convenience, there are front-ends like ZuluCrypt that can help manage LUKS containers without getting too deep into the command line if you prefer a GUI.

If you’re comfortable with the terminal, the classic cryptsetup commands give you full control over every step.

Another option is gocryptfs, which offers a user-space encrypted overlay filesystem. It’s open source and lightweight, but the security model is different from LUKS.
