Brainy

I have been searching through lots of popular encryption algorithms but i cant seem to find one just like it. What am I missing?

  • You have managed to solve the first part? The file with all the "+-.[ "-symbols ? There are more parts to this, and the first one has nothing to do with popular encryption algorithms :)

    Would also appreciate some help. I know which popular enc algorithm that is used and I have managed to generate some values using the values you get in part 2. However I am not able to decrypt the password using those values. I just get some other gibberish :P If anyone could pm me it wouldve been great!

  • I have just solved it, so feel free to DM if you need anything!

  • 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.

    Dltd

  • 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

  • Damn, 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

    "I recognize, Mr. Reese, that there's a disparity between how much I know about you and how much you know about me. I know you'll be trying to close that gap as quickly as possible. But I should tell you... I'm a really private person."

  • 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

    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.

  • Amen to coding !
    That snake is huge ;-P

    1) name of the challenge gives a hint
    2) WEIRD asymetric crypto

    Yes I cleared your first point before I posted. I understand what the second point (asymmetric crypto) is supposed to be, or at least I think I do, but my system cannot preform the math fast enough given the nature of the magnitude of the operations involved.

  • completed this challenge if need any help feel free to pm :) :)

  • solved within a few minutes. Nice easy challenge :)

  • Fun! Took me awhile, but still fun.
