I programmed a static password with the character "&" in it and it appears correctly in the field, but after programming it it Yubikey returns a "/" instead. When I compare keyboard layout then I see that that the shift-6 I entered on the Spanish keyboard is a slash on the US keyboard.

I am talking here about the binary version for Ubuntu 12.04 LTS:
version 3.1.8
library ver. 1.12.0

Hello.

The scan-code mode (used when you want to enter a password yourself) is very keyboard layout dependent.

The tool could probably be proved for this.. but it's a bit tricky to capture this in a meaningful way.
So what the tool does is take what you enter and convert it to the US scan code equivalent. So if you want to control exactly what is sent to the key you need to convert your strings to scan codes for your layout and then enter that in the "scan codes" field in the tool.

Hi,

I'm also running into spechial chars problem. Tryed to toy around with the "scan codes" field but caused a

"Speicherzugriffsfehler" == "memory access violation"

in the yubikey-personalization-gui when I put in "ad" which should result in "_".

Could you please provide more information about how to convert ASCII to "scan codes" (cli tools) and the language settings (german).

Regards,
Thomas

Hello,

As you've noted there's a bug with entering the raw scancodes.. A fix for this is already in the git repo (https://github.com/Yubico/yubikey-perso ... 948561c497) and will be in the next release.

Yeah, makes it quiet hard to use if you want to enter a specific password (especially with some ((german)) spezial-chars)...

A fix for this is in since the release of version 3.1.10, do you see issues with this since that version as well?

Hello,

To be clear, the bug discussed here is that when you enter a scancode password by entering the raw scancodes the application crashes, is that what you're seeing?

If the issue you're seeing is that some characters you enter come out another way that's more or less expected when you're not using a US keyboard. There is no way (or at least no good way) for the application to know what layout you're using or what scancodes the characters you enter correspond to. So it's mapping the characters you enter to US scancodes.
(see https://github.com/Yubico/yubikey-perso ... /issues/19)

I actually get the error described there, the application does not crash.

I made a quick sketch about the problem:

( Source for the Keyboard => Numbers convertions: http://help.adobe.com/en_US/AS2LCR/Flash_10.0/help.html?content=00000520.html )

Is this around right? Then I'd have some ideas how to solve this...

Btw: The posts you mention are almost 6 months old...

Hello,

Yes, that is a good summary of the problem, though the scancodes are not ascii but according to this (http://www.win.tue.nl/~aeb/linux/kbd/scancodes-14.html) table for us keyboard. The code in the personalization tool to handle this is at https://github.com/Yubico/yubikey-perso ... anedit.cpp

We're happy to receive any contributions of either code or ideas to make the personalization tool better!
