I tested encryption on USB with user password required and it works ok.
I observed that the password can be set only one time (first time).
We need the user to be able to set a different password every time wants to encrypt something.
We need to sent confidential info encrypted on USB to different clients.
It not ok to have the same password set for every encryption I do for different clients.
Another issue is that maybe a bank officer set the password now (lets say moment t0) and after a month when he needs to encrypt again he will do it but it's possible not to remember the password for decryption because of the long period in time from the moment t0. So it will be more naturally to set a password every time a user is doing a new encryption.
From what I understood there is no workaround for this in the current version so I would like to open a Feature Request.
