Test

Source : https://developers.yubico.com/yubikey-personalization/Manuals/ykchalresp.1.html

The YubiKey challenge-response operation can be demonstrated using the NIST PUB 198 A.2 test vector.

First, program a YubiKey with the test vector :

ykpersonalize -2 -ochal-resp -ochal-hmac -ohmac-lt64 -a303132333435363738393a3b3c3d3e3f40414243
...
Commit? (y/n) [n]: y
$

Now, send the NIST test challenge to the YubiKey and verify the result matches the expected :

ykchalresp -2 'Sample #2'
0922d3405faa3d194f82a45830737d5cc6c75d24

Action

sudo apt-get install keepassxc
ouid=$(dd if=/dev/urandom 2>/dev/null | tr -d '[:upper:]' | tr -cd '[:xdigit:]' | fold -w40 | head -1) ykpersonalize -2 -ochal-resp -ochal-hmac -ohmac-lt64 -a${ouid} # Même chose avec la clef de secoure ykpersonalize -2 -ochal-resp -ochal-hmac -ohmac-lt64 -a${ouid}
