Crytch (“encrypt a sketch”) is an online tool for creating encrypted messages. It follows the concept of visual cryptography: The information is present but hidden in chaos while only the correct key can reassemble the correct image. Inspired by the techniques from Moni Naor and Adi Shamir, we translated the idea to digital vector line-drawings: When anchorpoints are separately moved in different directions, the original image becomes distorted, lines that previously displayed information become meaningless.
