What are the compile instructions needed for this? "file not found with <angled> include; use "quotes" instead"

[vallamost]

I've tried using the make file and using gcc but I still get errors about Yubi header files on OSX. I downloaded the Yubi tool CLI resources and put the header files it's looking for right next to the yubicrack.c file as seen in the CLI output. Am I missing something obvious?

I'm not familiar with compiling C files but this seems like it shouldn't be too hard. Seeing how this repo is 14 years maybe something is outdated, lol

I am working this out as well.

apt-get install libykpers-1-dev

gcc -I/usr/include/ykpers-1 yubicrack.c

[rbeede]

This is closer, but it appears the library has changed in later versions so not compatible with this code:

gcc -I/usr/include/ykpers-1 -I/usr/include yubicrack.c


# Result

yubicrack.c:(.text+0x1f4): undefined reference to `yk_write_config'

https://developers.yubico.com/yubikey-personalization/Release_Notes.html

Use yk_write_command() instead of yk_write_config().

Gave up on compiling this and tried a slow bash variant:

cat yubikey_bruteforce_access_code.bash

#for ((i=0; i < 281474976710656; i++)); do

for ((i=0; i < 16; i++)); do

echo $i

access_code=$(printf "%012x" $i)

echo $access_code

if ykpersonalize -y -1 -z -c$access_code; then
echo FOUND ACCESS CODE $i
exit
fi


done

Pick the sequence range you want to try. There are 48-bits in the access code.
