Aplikacja to notatnik do którego dostęp zabezpieczony jest odciskiem palca. Przeznacozna dla 1 użytkownika.
|
||||||
|
|
||||||
|
## Wykorzystane mechanizmy bezpieczeństwa
|
||||||
|
|
||||||
|
1. Notatki są zaszyfrowane algorytmem AES-256 w trybie CBC.
|
||||||
|
2. Padding
|
||||||
|
3. Wektor początkowy generowany jest losowo przez SecureRandom.
|
||||||
|
4. Klucz jest przechowywany w Android Key Store - hardwearowo zabezpieczonym miejscu.
|
||||||
|
5. Ochrona przed rootowaniem dzięki ustawieniu setUserAuthenticationRequired(true)
