HashMask is a JQuery Plugin that produces an unique and a irreversible visualization of a user’s password. The attempt of this application is to find a more secure middle ground between clear and masked passwords. Based on the generated image, users would be able to confirm that they have entered the password correctly, since they are becoming familiar with the image they see every time they type the password.
Technically speaking, it uses a subset of the sha1 hash of the password as the seed for the sparkline’s shape and color. It should be relatively safe from reverse engineering as a result. There is the potential to estimate a possible range of characters of the first section of the hash, but overall this should be a extremely low risk.
