About QDC

Quadrant Drift Cipher Family

QDC is a path-based encryption algorithm designed for educational purposes. It illustrates the progression from simple encoding to complex, chained encryption.

v1: Simple path mapping. Very high leakage.
v1.1: Introduces whitening to destroy frequency patterns.
v2: Advanced nonlinearity and chaining. Resists replay attacks and provides avalanche effects.

WARNING: This lab is for educational use only. None of these algorithms are cryptographically secure. Use AES or Libsodium for real-world production security.
