Pwn2Win CTF 2016: Timekeeper's Lock

This is the challenge.

In order to protect their maximum security facilities, the Club employs an electronic security lock activated by a 256-bit key which changes every minute. When a Club member is authorized to enter some of these facilities, he receives this key in hexadecimal format, the same format which is used to enter the key in the electronic lock’s keyboard. The last year (in 2015),
