I could really use any kind of hint, got my mind stuck

I recognize the first part. Next part, not so much. Any ideas?

Me too…

I believe I solved that one while having some leftovers from the chinese takeway. It rocked.

I got some “chinese” code but it does not like a flag and it is not a valid flag. Someone could help me?

I hate 3 things:
1.) Esoteric Programming
2.) Asymmetric cryptography
3.) Lists

■■■■, I can’t figure out that last step… got some hex data, but any string encoding I found doesn’t work… I’ll have to think about n3m0’s list hint…

I feel like people didn’t appreciate this joke enough.
I have been laughing for a straight 10 minutes.

@melka it helps to understand what the output of that programming language looks like regardless of input. Try doing a hello world in that language on repl.it

Hi,

I’m stuck. I think it’s about the algorithm developed by Rives,Shamir and Aldeman :). Maybe someone can write me a message and we can discuss

thanks

  1. Search for esoteric languages
  2. Search for those letters and cipher
  3. Calculate de message, convert from hex to ascii.

solved, nice challenge

Anyone can help me with this ? I’ve solved the first and second part, i dont know what to do with the “decrypted” password!..If i convert it to ascii it is nonsense!

Before converting to ascii convert it to something 0x - looking

Thnx!

I’ve some doubts on the flag format. I got a password but HTB{password} doesn’t seem to work…

Ok… changed library for big numbers and got missing bytes… :angry:

What is the best language for handling the input to the second part of this challenge? I was trying Python but even after 24 hours, and my computer using half it’s resources it cannot even get m1 let alone further.
