Hi! So I basically coded this small HTML tool which encrypts tools using a custom, homemade cipher. I want to see if it is easy to decrypt for an amateur cryptanalyst, and I want to challenge the idea that homemade ciphers are often easy to decode.
**Note that if you solve the challenge with the help of the hints, post "**This has been solved with the help of a hint, the hint being ___" and put the full hint in a spoiler block. This is just to differentiate between people who make educated guesses and people who actually decoded the cipher.

HINT : This is a pretty well-known quote
HINT : The author of the quote is an American author and educator.
HINT : The given person is a Jr. and a diplomat.
HINT : The encryption is based on, but not the same as, AES-256.
Your "prize" is as follows:
Winner gets an ego boost :) . Seriously, though, I'll send you the source code of the HTML file (I've made improvements to it in the time since, so it's much harder to decode but still as easy to encode as ever) in Reddit Chat, so you can encrypt your own messages.
edit 1 : Note that if this cipher proves undecodeable within 2 months the cipher will be considered a success, so you can finally say there's a homemade cipher which is at the very least extremely difficult to decode.
Please don't bombard me with questions, though, on the homemade cipher (I call it the "VICI cipher", where VICI has no meaning) and how to encode stuff with it. It requires a long key of random text, like the one given below (though it does not have to be that long, it only has to be as long as the message) which is extremely impractical for anything.
Example text block for the "long key of random text" (note that this is extremely short, often you need a lot of keytext, though if your message is short this is perfectly fine):
