ZUPTPOST-QUANTUM BACKUP - (DEMO - LIMITED TO 34MB)
zupt 2.1.5

Post-Quantum Key Generation

Generate ML-KEM-768 + X25519 hybrid keypair for quantum-resistant encryption.

Creates a private key (keep secret — decrypts archives) and a public key (share freely — encrypts archives). Based on FIPS 203 and RFC 7748 — safe against both classical and quantum computers.
