The fault in our DES

Published date : 6. Mai 2020 23:44
Our engineer did a differential fautl analysis on a smart card - or rather he began the attack.
He went on vacation before the data analysis, so now it's your task, first year intern.

We'll give you the plaintext, the ciphertext, and 32 faulted ciphertexts.
You need to recover the 64 bits key and to submit it in hexadecimal inside the 42CTF{} tag.

Example : 42CTF{1234567890ABCDEF}

Good luck.
