I wrote this really trashy encoder in rust. See if you can figure out what it does and decode the flag.

Idk anything about multivariate cryptography, that won't stop me from making a challenge tho... key length is 15

do the math

modern cryptographic hashes are efficient and secure... my hash is neither 😃 note from author: the flag is left padded in this challenge so when searching for a solution make sure to check if the flag contains ictf{ instead of starts with ictf{

My key generator is broken but AES is so secure it probably doesn't matter.... right? nc 155.248.210.243 42191

merge sort but I'm dumb and don't know how to compare numbers, doesn't work most the time but makes a good shuffler... right?

The first time we've started on a Thursday this year, feels kinda gross tbh
