Caesar's Salad 2017 CTF | RC3 Writeup

It all started with the sentence 'An affinity for Caesar's salad'.

The first part, finding out that it was Caesar's algorithm, so GPUNCH_AITIL with an 8 rotation became YHMFUZ_SALAD.

Great, now we knew the second word. Unfortunately, the first part didn't appear to be only Caesar's encoded.

While browsing what types of encoding were there that could be related to Caesar's, my eyes stumbled across the Affinity encoding section.

 'An affinity for Caesar's salad'.

Bruteforcing my way through the Affinity encoding algorithm, the word GARDEN popped up as one of the results.

And so, the flag RC3{GARDEN_SALAD} flag was born.

This one took me longer that I am proud to admit it should have, but hey, I got it.
