Where's your God now? :twisted:
I actually wanted to make this really tricky but after thinking of a pretty cool solution which would probably trip a lot of guys up, I quickly saw a lot of pitfalls in trying to reverse it, so with limited time to work on this, i gave up and settled for just not giving any hints and relying on security through obscurity ;)

btw it will be fairly obvious when you get the plain text so no need to spoil for confirmation

Just trailing here, but is this something solvable using a cryptogram approach?

Show off! lol. You've accomplished your mission i think. Simplicity has made this hard as hell since there are no edges to get our fingers under.

I'm not giving up. I've already tried a dozen different encryption methods to no avail. I have discovered a few interesting details about the code tho that i'm hoping will help me figure out how its coded. Still working.

I have used a custom 'algorithm' which is vulnerable to a specific type of attack

pretentious,

I've been working on this for about 6 hours now. I'd really like to ask you some specific questions about this, but I'm not authorized to email you messages. :? (new to HTS, so not sure when this will be enabled for me)
Anyways, I feel like I'm close, but I'm just not getting it, can you message me a hint?

Make another post (think it's >=2 posts for pm's) then message me with whatever you need

Am I the first one to solve?
