I might be a few months late, but I finally found some time to publish my "magnetic_tape" crypto challenge from #NullCon #Berlin #HackIM #CTF 2025:

https://github.com/OOTS/magnetic_tape

I included the source code (was published anyway during the CTF), my own solution, my own #writeup, and some internal files (#Dockerfile, docker-compose, minimal #python #unittests).

Also: #NullCon #Goa #HackIM #CTF 2026 is happening in a few days: https://ctf.nullcon.net
Go check it out!
