Chroma-Hash: A Belated Introduction : An interesting experiment. As you enter your password, it gets hashed and convert to three colored bars in real-time. So, you come to know the “colors” of your password, and can tell if you entered it right before you hit enter.
If your password normally is represented as “red, purple, orange”, and after you’ve finished typing you see “pink, green, grey”, you’ll know you mistyped it somewhere along the way. This avoids a potentially long wait for the server to respond with a “failed login” notice.
It’s neat, but I can’t say it’s fixing a huge problem for anyone, I guess.
