We recommend you use:

  • VeraCrypt to share encrypted files across different operating systems.
  • LUKS to encrypt files for Tails and Linux.

  1. See the difference between file containers and partitions.

  2. Plausible deniability: in some cases (for example, with VeraCrypt hidden volumes), it is impossible for an adversary to technically prove the existence of an encrypted volume.

    Still, deniable encryption might not protect you if you are forced to reveal the existence of the encrypted volume. See VeraCrypt: Plausible Deniability.
