During the end of high school and the beginning of university (much before discovering proper cryptography) I played a lot with steganography, which is the art of hiding text in places which don't seem to contain any. The (silly) goal was to create methods for generating, say, family heirlooms which would then be decoded 200 years from now, giving the coordinates to a secret treasure.
This can work only if the concealing methods are hard, but not impossible, to decode.
And so here we are! These are some concealing methods I created, and I encourage you to try and decode/break them. Every method hides a "solution" which is some text (either a word or a short phrase, though note that the result could be in Italian) which you can submit in the text box to see if it's correct. Have fun and let me know if you can decode some of these!
Note: every method is easily breakable with a dictionary attack, but that takes the fun out of the puzzle.
