Untitled Cascade Encryption Project

Hello! :) I LOVE CRYPTOGRAPHY! I had to say it in all caps, because it's my favorite thing.

The past 2 weeks have been very slow for me, so I decided to fiddle around with different ciphers and ended up making some of my own even.

I read the rules and this is not a "Solve my code guise!" thread.

I simply wish to share this on reddit, after working for so many hours on it. I feel proud of it, and think it deserves to be immortalized on the web. ^^

So! A cascade encryption. What's that you may ask? It's a plaintext encrypted multiple times through different ciphers with their own keys.

Should you be able to solve the first layer of it, you would still need to go through all the remaining layers in order to decrypt it.

I'll show you the code now, and tell you about it underneath.

The small image is the original size. 2 KB's of data in pixel format. Beneath is an enlarged version with 5x5 pixels representing a single pixel.

You could also convert this image into a number format from 1-5 based on pixel color, line by line.

This project is a result of 13 different layers, utilizing both substitution and transposition. There are also no double letters, and I've tried my best to obfuscate any signs of letter frequencies showing up once you're past the initial color and shape encoded starting layer.

Now, I don't wish to reveal any of the keys or ciphers I've used. I've very protective of the inner workings of my creation right now. It's my little baby!

But I'll gladly share the encrypted text. "The quick brown fox jumps over the lazy dog."

As this is a very small plaintext, it's really only at 12 layers currently. There's a final transposition layer once the text is large enough to use it.

But, that's pretty much it. My nameless creation that I'm very happy to have been able to make! :)

It is very important to me.

I have never put so much work into something like this before, so I hope you won't be too mean if this wasn't what you expected to find from reading the title, hehe!
