I need help with iris and Plato arg
So, I found an ARG on nightmind index called "iris and Plato". The story is about a girl who's website is hijacked by something. It's also inspired by the Plato's cave.
But that's not the point. I need help with a specific puzzle.
And here, you can go and try the ARG yourself, or continue reading. I'll tell you what I found so far, so this is a spoiler. But once you click on the robot cafe article and go to source code, you'll find a Pastebin link in the comment. The Pastebin is password protected. If you look at Nicky's SoundCloud, you'll see the track called "cave". If you put it through spectrogram, you'll see the password is "underthesun".
Once you have access to the Pastebin, it's encrypted with vigenere cipher, with some letters being replaced by numbers and symbols. On the website, once you click on one of the pages and put the soundtrack to it called "new alphabet" through spectrogram, you'll see the key to converting the numbers and symbols to letters.
Here's the part where I need help. Once you put the final result of only letters through vigenere decoder, you get a text that talks about "the iris cafe". But the text has different misspellings. There's a lot of them. So I want to see what plaintext you get to compare it to mine, and see if the misspellings in the final result are due to it being another cipher or me interpreting the symbols from the "new alphabet" incorrectly.
