NoteCrypt Encrypted Notes vs The PDF Signer App

NoteCrypt combines strong 256-bit AES encryption, and rugged simplicity. NoteCrypt will prevent even the most determined and well-resourced attacker from accessing your notes, even if they physically possess and can unlock your device. NoteCrypt goes to extreme lengths to secure your notes: - Applies 256-bit AES encryption to the full notes database - Uses the PBKDF2 key derivation and stretching function - Does not store your password, making your notes impossible to decrypt without it - Does not have cloud integration or login - Does not use analytics - Uses 'salt' to prevent 'rainbow table' attacks - Foils 'known plaintext' attacks by encrypting big blocks of data including metadata - Erases the in-memory copy of your notes when leaving the app - Prevents notes showing in the app switcher - Does not support Touch ID so as to not compromise on security NoteCrypt also has the following usability features: - Simple, no-nonsense design - Provides an indicator on the strength of your password - Allows you to change your password - Dark themed UI In summary, NoteCrypt works the hardest to secure your notes.
