I'm too shy to ask,
so I put on a mask.
Made of bits and pieces
I hope my loneliness ceases.

If you think I am the one
I'll always be true,
but if you think I'm a zero
I'll be nothing to you.

I'll give you my numbers
you might think they're high
but split them in half
I might be your guy!

The numbers:

12645
14073
15201
13925
14196
13550
6497

What do I say, and what do you answer?

  • $\begingroup$ So unconventional encoding = puzzles on here? See them a lot lately but I don't get the thrill $\endgroup$ – user1886419 Sep 29 '16 at 23:02

    $\begingroup$ @user1886419 Yes, in my opinion it's considered a puzzle because it fits the cipher tag and plus you also have to figure out the algorithm rather than just the encoding/encryption. He also gives enough clues in the riddle in order to do that, which differentiates it from poor-quality code puzzles. Of course it's a personal preference whether you like these or not, but I certainly think they're on-topic. $\endgroup$ – user14478 Sep 30 '16 at 8:29

You said

bemyvalentine!

Because

Convert all numbers from decimal to binary, then split all results in half and treat them as bytes; Then convert back to ASCII.

And my answer is

11493
7404
10740
13047
13541
3891


Here's a (dirty) fiddle for encoding/decoding strings with this technique, with OP's message as initial input. Unfortunately it only works in a specific range on ASCII codes, if for example a space is included it's hard to tell where to split the part in half.

I hope I can motivate more users with this to include such programs for encrypting a self-created cipher in their answers or directly from the questioner in their wrap-up posts.
