When booting CD-Knoppix, you have the option save the /home directory via encrypted image file. You are asked for a password and you can supply it with any ascii-character (including spaces).

But, once Knoppix installed, I want to make an encrypted image file, via /dev/loopx mounting, then I CAN NOT input spaces in passwords.

What happens? What kind of image file is created within CD-Knoppix?

TIA
