GitHub - cyb3rko/pincredible: Modern and secure Android app to help you remember any PIN
github.comAny thoughts on this one?
Just in case anyone needs an eli5 (not me, obviously, I totally understood how it works 🙄)
Of course! I’ll simplify everything for you.
Imagine you have a toy box with a secret toy hidden inside. This app works in a similar way to hide and protect your secret number (PIN).
How it hides your PIN:
-
PIN in a Puzzle: The app places your PIN in a puzzle-like grid and fills up the rest with random numbers. It’s like hiding a toy among many other toys.
- Even the app doesn’t know where your secret toy (PIN) is in the grid.
- If someone tries to peek over your shoulder, they won’t easily figure out which toy is your secret one.
-
Special Keyboard: Instead of using the regular way of typing, the app gives you a special keyboard inside it.
- This makes it hard for sneaky apps to see what you type.
- Also, the buttons on this keyboard keep changing places, so if someone is trying to see where you touch, they’ll get confused.
How it keeps things safe inside:
-
Magic Lock (Encryption): The app uses a magic spell (called AES) to lock your secret toy so that even if someone gets it, they can’t play with it without the magic key.
-
Secret Name-Tag (Hashing): Every toy (PIN) gets a secret name-tag that only the app can read. It’s like writing a name in a language only the app understands.
-
Strong Password: If you ever forget things and need a backup way to get your toy, the app has a super-strong password system (called Argon2id).
What happens when you use the app:
-
Starting the App: The app looks for your toys (PINs) using the magic key and shows you their secret name-tags.
-
Picking a Toy (PIN): When you choose a toy by its name-tag, the app shows you the toy in its puzzle grid, but hidden among other toys.
-
Adding a New Toy (PIN): If you get a new toy, you can give it a secret spot in the grid and a secret name-tag. The app will use its magic spell to lock it up safe.
In short: This app is like a magical toy box. It hides your secret toys (PINs) in clever ways and uses special magic to keep them safe.
