This project lets you hide secret messages in your comments! To hide a message, type "hide", and tell the project the decoy message (what your comment will look like), the key (this is a secret number, like a password, that prevents people from decoding the secret message unless they know this key; you can leave it blank), and your secret message. To reveal a message, type "reveal", and tell the project the comment and the key (leave this blank if no key was used.) Don't use this to bypass the filterbot or break the community guidelines. I may change the methods used in this project, so if you want to make sure a message can be read indefinitely into the future, remix this project. # FAQ: ## How does this work? This project hides invisible characters between the first and second letters of your decoy message! These invisible characters encode your secret message, so that when someone puts your message into this with the correct key, they can decode it. ## How does the text encoding work? The text is encoded into base-10, using all the printable ASCII characters. Then, each digit corresponds to a different invisible character. ## How does the key encryption work? For each digit of the base-10 encoded text, the corresponding digit of the key is added, and then it's modded by 10. If you want a secure key, make sure to 1) use a secure random number generator, 2) make it at least as long as the text, and 3) create a new key each time. ## Steganography? Is that a dinosaur? Nope! Steganography is the process of hiding a secret message so that no one except the intended recipient will know that it's there. https://en.wikipedia.org/wiki/Steganography ## Do you plan on making any changes? I might change the location of the invisible characters to the beginning or end, as you can sometimes tell if there's invisible characters between letters. ## Why doesn't this work with some character set/some language? The secret message must be in printable ASCII (https://en.wikipedia.org/wiki/ASCII ), due to the way it's encoded. One of the invisible characters used is the left-to-right override character, so if the decoy message contains right-to-left text, it might mess that up.
