Hello to everyone!
This was one hard form my n00b skills)
I readed all forum topics about mission 6, watched youtube for ASCII + wikipedia and I didn't understand a sh*t man!

Then I just beginned to play with encryption form but before I tried a lot using cryptii.com - I where thinking that maybe its Enigma encoded

Okay.
I entered aaaaa and I got abcde, after bbbb - bcdefgh.
What we see? Progression, so I used
https://en.wikipedia.org/wiki/English_alphabet alphabet and decoded d8f;ejjm in our progression stile and got passed to next level.
I liked this one and it toked 3-4 hours me to agues and understand besides I have no previous experience.
I tried and decoded to everything its possible and I made much harder things buy trying to guess resolution and as we see - its much simpler than I thought.
Thank you very much HTS community!
I love you all!
