Description

Keygen challenge that tries its best to not let you debug it

segfault on 12:14 PM 11/01/2018: It is interesting for a beginner! If it is okay to ask this,is there a stack overflow or something similar?

daniellimws on 12:36 PM 11/03/2018: Hmm there shouldn't be. If something goes wrong please let me know.

segfault on 5:22 PM 11/03/2018: When I pipe huge amount of char to the program,every time I run executable, it tries to input extra characters that are left from initial running.

daniellimws on 2:15 AM 11/06/2018: This is just because the program only reads in a certain amount of bytes. The rest does not get read by the program and so your terminal will read it instead.
