Writeup by iv3l for Rituel en chaine

Just like in Rituel du boutisme challenge, I used the exact same strings + grep combo and a for loop. The -e option selects which encoding to use.

s : 7 bits (ASCII)
S : 8 bits (extended ASCII)
b : 16 bits big-endian
l : 16 bits little-endian
B : 32 bits big-endian
L : 32 bits little-endian

$ for e in s S b l B L; do strings -e $e rituel-en-chaine.img | grep FCSC; done
FCSC{6b8aa82937ec0ff5a3eaffa74b3b2de2e83c6a94eef6d96b59b50f65e8e35fa9}
