Linux Unicode Passwords
Kenneth
Is it possible to use unicode characters (ie. Japanese, Chinese) as a
Linux password?
Thanks,
Kenneth

Yes, but.
You'd generally be advised against it if you wish to be able to login
from diverse systems where you might not be able to easily input it.
Also you'd have to have a suitable keymap system in place already
on the local *dm or getty login screen (I'm sure it's doable, don't
know if it's common practice though).

how can you type Chinese before you login?

Apart from the previouly mentioned troubles, using Unicode for passwords
doesn't improve the security, eight characters out of the ASCII alphabet
(chars #32-127) is quite much ;-) Adding stuffing bits and bytes
(unicode characters or encodings take up more bits) does not increase
the mathematical randomness - so it is rather a convenience matter.
In fact I do agree with your idea of "localized passwords", but I know
what a lot of trouble only about 7 special characters are (in my country
they use "ä" and similar (an "a" with two dots above). You might try to
log onto a computer via serial terminal and wonder why your password
doesn't work... Even typing a simple text (or email on my PDA) all those
special characters are trouble, so I rather not type them in many cases
and stick to the basic English (actually Roman) charset if I can... Ever
tried to port some C sources from Windows to Linux with the Windows guy
using special characters in his comments? So if your keyboard has
special letters on it, use them to remember your password, but try to
type the passwords in roman letters ;-)
Hope you have fun ;-)

Presumably the same way you type Chinese after you login. Things have to be
set up to handle these characters before the login prompts.

The problem one will run into is that not everywhere is an IME loaded
when you need it. Or you prepare a PAM module or something for your
sshd that does translate romaji input into CJK before passing it
on...
Oh, never forget Alt+16458!
