What Can CryptNote Do? Key Features
Military-grade Encryption
CryptNote uses AES-256 encryption, the same standard used by governments and militaries worldwide, to ensure your data is protected from unauthorized access. This level of encryption guarantees that only the intended recipient can decrypt and view the shared content.
Auto-Destruction
Links generated by CryptNote automatically expire after the first view, ensuring that your sensitive information is not exposed or accessible beyond its intended use. This feature eliminates the risk of data leaks from shared links.
Password Protection
For added security, users can set a password that must be entered to view the shared content. This optional feature ensures that even if the link is intercepted, the content remains inaccessible without the correct password.

Automatic Cleanup
Old data is automatically removed from CryptNote's servers, ensuring that no residual information is left behind. This feature enhances privacy and reduces the risk of data breaches.
