Randomised Key Generation

A Python project exploring secure cryptographic key generation using ECDH, multiple entropy sources, HKDF-SHA512, and AES-256-GCM.

Features

ECDH key exchange using SECP256R1 (P-256)
Multiple entropy sources
HKDF-SHA512 key derivation
AES-256-GCM encryption and decryption
Experimental image-based key generation
