Nobody solved this super complicated cryptography puzzle last time. I guess I have created an unsolvable mystery of epic proportions. Anyway, if you wanna give it a try, go ahead:

Answer is a sentence in plain english. Space is used, but no punctuation. Post answer to comments. Good luck :D

Hello World

No, @hypervtechnics

@ClySuva Worth a try

.

Do I have to guess a key?

It's not hash. Encoding is close.

Post it to 4chan and watch the madness if no one really haven't solved it yet.

You guys think it is hash because it looks like hex encoded binary. You can decode it into binary, but this would actually take you further from the solution. :)

I'm very confused.

I'll solve it tomorrow :)

.

It has 0-9 and A-D. No e,f so definitely looks like hex. Or at worst base 14.

It has 32 characters. That's gotta mean something. So no substitution or shift ciphers.

Come on, need a small hint at least. Am I on the right track?

It's a puzzle, not an every day encrypted message, hence it contains several tricks to guide you into false assumptions. First word is "real"

.

Maybe the first 4 bits are represended by a character. Thdn you'd combine each 2 letters. Since it's encoding, it could be it.

I was just interested :)

@BlueNutterfly you always seem to disappear for a while and then you come back and i always seem spammed with ++'s from you xD

@c3ypt1c EXPOSED :P

So nobody managed to solve it. So yeah, it's just a character substitution cypher with reduced alphabet. Just 13 letters, and a space, making it possible to encode two characters in one byte.

Hardest part of the puzzle is figuring out what the puzzle is not. There are several false clues in there, including the length, hex alphabet and reduced alphabet.

I was so sure HEX was the right way :(
It yielded me base64 even
