My friend sent me a "puzzle" in binary, and said that there are multiple steps to solving the puzzle, all of them including decryption. I translated the binary into text and he said that was a good first step, but I have absolutely no idea what cipher to use past that on the text. He said it requires a key and that the post he sent me should have all I need to solve the puzzle. Unfortunately, I'm completely stumped. I've been locked into using a Vigenere cipher because I believe he hid a keyword somehow, but I'm afraid I might be tunneling on that too hard. Can you help me figure out the next step?

Here's the full "puzzle" he sent me. Whether it's a copypasta, I do not know.

Alright so to quell my boredom I have decided to make a puzzle, whoever solves this puzzle and tells me the answer will get $100 cold cash in their hand. For each day that passes I will give one hint but the cash will drop 10 dollars for each hint. The first hint is free, no this puzzle isn't just conversion that's just a step.

Puzzle #1

 01000100 00100000 01011000 01010100 00100000 01010111 00110011

Good luck.

Translating the binary to text yields: IB HN A C VU K XT 9 P7K ZGG RP 20 3Q L KI D XT W3

That's as far as I've gotten.


Hint 1: The creator has posted a hint.

It's something that makes him happy.

    $\begingroup$ He's posted an update on Reddit: 'Edit: He has provided a second hint. This is something that makes him "happy".' $\endgroup$

    $\begingroup$ @moonbutt74 Seems like from the Reddit page the OP has solved the second layer with a "smile cipher" (likely what the hint from Demesne was referring to). The cipher decryption tool can be found at: enisoc.com/smile.php but without knowledge of the key or more codes it will be impossible to solve. Indeed on the Reddit page the OP was told he/she was given the key to solve it. $\endgroup$

1 Answer 1


Is it



Your letters after decrypting the binary, as shown by @Brian, combine to make almost every letter in the alphabet. Taking the letters not make, EFJMOSY, I can make the word: EmoSys. I removed the numbers because I didn't think it would do anything related to a word that makes him happy

Hint 2:

It makes me happy; EmoSys is a company out of the Netherlands that specifically makes items that help people with depression, hence the 'makes me happy.' If he was depressed, EmoSys would help make him happy.

This was all I could come up with out of this cipher.
