You no need to tell me that my method is wrong because I know that it is wrong . This is the cause why I am asking for a hint because my method is wrong and leads me to nothing . I made intensive research on the type of cipher used in the challenge or the type of encryption but I did not find anything in Google . Moreover the forum does not help me and whatsoever I did , I got a nonsense string of letters.
You shouldnt post exactly what you are doing. If by chance you are doing it almost correctly, you would be spoiling the challenge to others. Edit your post and re enter your question in a way it is not a spoil.
Btw, your method is wrong, thats why you cant find the answer.
research won't help you much on this one. The only way to solve it is actually to try a few things. once you get it, it'll be crystal clear that you have the right way to solve. So keep on trying things.
I just solved this one. Had the right method when I first looked at it, but after decrypting four letters I figured that they couldn't possible form a word, so I gave up and tried other things. Turns out that of the first six letters, three are incorrect. There's even a mistake in the solution string! Truly disappointing.
If you're still working on this, start from the third line so this doesn't happen to you. Most of the errors are concentrated in the first two lines.
