Crypto > Sick Teacher

hahaaha me forget to use HTB{flag} :mrgreen:

– ignore me –

Just testing if signature is working… The script one won’t work, just image :frowning:

First of all, you should look at “JIWZHMC118”, then try to search on HTB site something connected with 118 in the name (1st hint).
After that you can use helpful website http://rumkin.com/tools/cipher/cryptogram.php
Remember, that first thought is always the best. Don’t look for so andvanced idea to decode this.

Dude, this topic was resolved already xD

Take a look at my post here (Crypto > Sick Teacher - #8 by JChris - Challenges - Hack The Box :: Forums)

Indeed, the “JIWZHMC118” is a very special one and I did use it.

need help, i tried 0 - 26 cipher caesar, i search whant all htb site about JIWZHMC118 and no find nothing. I applied the cipher in different words, almost all of txt and one by one separated, with no results … could someone give me a light?

There’s a tool that I find very useful when trying to break/analyze crypto… Called CryptoTool or JCryptoTool, depending on which you can find. Both have great visualization/cryptanalysis features. Check them out.

Can someone DM me about how to submit the flag for this? I was able to decrypt the message. Tried to submit the key and threw it in the format HTB{key}. Not sure what I’m doing wrong.

Read the challenge desc. Needs to be submitted in the correct case

I have tried the flag and the key in low, upper, inside HTB{}, outside HTB{} but nothing works.

Any hints?

May I message someone about this Challenge? I have the plain, I feel like I’m just messing up the formatting, if not, I’d prefer no hint!

shoot

Note to the uninitiated, check the hashes of the files and plaintexts you are working on! You may have incomplete data! slaps head

Thanks gm67445.

Man thanks for this, you just saved me time of confused desperation

For me, as a total n00b, this was a lot of fun.

Spoiler Removed - Arrexel

i solved …ty all

ok i make a hint for all …make manual decrypter from Cryptool

This was a fun one!

I have found the various tools for different ciphers on https://www.dcode.fr to be particularly useful for the crypto challenges I’ve done thus far. Don’t speak French, but doing a Google search for a specific cipher and going to the link dcode.fr has for it usually works fine.
Most of them are pretty interactive, and helps you whittle things down.
