## ltseorg (crypto, 4 points, 93 solves)	make some (charlie)hash collisions!
In this task we were given a code with function hashing strings and were asked to createa hash collision. After reading the algorithm, we quickly noticed that the padding function was non-standard and flawed:```def pad_msg(msg):	while not (len(msg) % 16 == 0): msg+="\x00"	return msg```This simply added `\x00` bytes until message length is divisible by 16. That means thattwo messages: "a" and "a\x00", although being different, create same hashes. After sendingthem to the server, we receive the flag.
