it's a reverse challenge, and fun

Regardless of whether this challenges about reverse engineering or exploit, i think xor must be important ;). IMHO RE and Exploit are an inseparable topic because to master binary exploitation, of course you have to master RE too

Thanks for awesome challenge! Took me a long time and had to research a lot, but is worth the effort for people wanting to master binary. Anyone planning on solving binary or reversing problems cannot avoid learning about machine code instructions and registers, so you might as well start now if you already haven't.

The only problem i had here was with endianess, but thats because of my intelligence. Good chal, ego boosted

I think it's a reversing problem too

That was a very fun challenge! Thank you! ^-^

VERY HARD

in my opinion, this problem should be at the reversing category
