Hi, I have a few stupid questions. The gui is qt. If I have qgtkstyle installed, will I get a gtk style in zulucrypt/cryptsetup ?
what desktop environment are you using? how do i apply this style? I can check for you if you are using gnome and are asking if the app can accept different themes as selected somewhere in gnome panel.
The other question is : if I want to crypt a file system on a USB stick how can I do it with this tool ? Should I do it from within the running system ? What if I do it from the classic system running, applied on the squashfs file and so ? (Is it a question which could have an interest, or is it definitely "from the running system on the live usb, let's say persistent mode ?)
Thanks for your patience,
You have too many scenarios and i cant keep them straight long enough to construct a coherent response.
But let me attempt to answer you and see if i got your question(s) right.
if you want to encrypt a usb mass storage device like a thumb drive, then open the tool,menu-> "create encrypted partition" and a list of non system partitions will be shown, select the drive from the list and then double click it and another dialog box will show up and you will create the encrypted partition here.
When you want to open the volume in the drive, go to the menu->open encrypted partition and the drive will be on the list, double click it and you will be asked to enter a passphrase to open it.
You do not encrypt the file system on the disk, the disk will be formatted and all of its contents will be removed.The encrypted partition will then be created and then a new filesystem will be created inside the encrypted partition so if you want to encrypt a partition on a drive, more its content someplace else, create the encrypted partition, open it and then more you files back. Always remember to close the volume when done to secure your belongings.
Its a program, like any other program, if you can start it up and if the system can see your usb stick and the usb stick does not have an entry in /etc/fstab or /etc/crypttab, then this tool can create an encrypted file system in it. So the tool can function as expected even when run from the live cd.
You can not encrypt a usb stick or a cd if you want to boot from it because how would the boot up process decrypt it to load the OS?
