Encryption Fundamentals & Cryptographic Principles
A simple algorithm that uses a 256-bit key to encrypt a message. While its strength isn't its strong point, it's a great way to learn about encryption!
The Mathematics of Modern Encryption
Modern encryption uses advanced mathematical concepts including modular arithmetic, elliptic curves, and computational complexity theory to ensure data remains secure even against quantum computers.
AES encryption in CBC mode
Zero-Knowledge Security Architecture
The application implements a zero-knowledge architecture where the system never has access to user data or encryption keys. This ensures maximum privacy and security through cryptographic guarantees.
Client-Side Encryption
All encryption operations occur locally on the user's device. The application never transmits plaintext or encryption keys over the network, ensuring complete data privacy.
Key derivation from user password
Secure Key Management
Encryption keys are derived from user passwords using PBKDF2 with high iteration counts. Keys are never stored in plaintext and are only available in memory during active sessions.
HMAC for message authentication
End-to-End Encryption
Data remains encrypted throughout the entire transmission process. Even if intercepted, the data is cryptographically secure and cannot be decrypted without the proper keys.
AES decryption process
Advanced Cryptographic Algorithms
The system employs multiple layers of cryptographic protection, combining symmetric encryption, key derivation, and message authentication to create a robust security framework.
