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
