I would like to have the option to encrypt and protect with a password the licence keys and connection settings stored by RUT - Viewer.
I think this is something better done by the applications specifically made for the purpose of encrypting discs (and removable discs for that matter). Here is a good article on the subject.
In other words, it's much better and safer to encrypt the entire USB-Drive than building encryption capabilities into RUT-Viewer.
A USB stick is easily lost or stolen...
Absolutely. I always encrypt (and backup) all my drives including removable ones. Better safe than sorry. :)
A word of warning to you and everyone using the portable RUT-Viewer version: RUT-Viewer allows to save passwords and copy licenses out of the License Storage. We bear no responsibility for any damage suffered by a user through the use of a non-encrypted drive. We strongly recommend encrypting your removable drives and even your laptop drives as this is a common practice nowadays.
Thank you for highlighting this issue. It will be useful for others to know. We'll also add information about the necessity of having your drives encrypted on the RUT-Viewer Portable download page.
RUT-Server runs as a service. If you run services.msc (Services Console) you can see 'Usoris R-Server' in the list of services, which is run automatically.
While you can hide the program icon and disable connection notification, we do not provide an option to conceal the program's process in the Task Manager list of processes, if that what you meant. Because this will make the program kind of shady and antivirus software may treat RUT as suspicious.
