Post-Quantum Cryptography
summary
Quantum computers threaten long-term secrecy, so the actionable claims are: move now, because recorded ciphertext can be decrypted later; use Open Quantum Safe and the lib to swap schemes; deploy hybrid concatenation (classical ECDH + post‑quantum key share) to retain safety; integrate post‑quantum candidates (NewHope, Frodo, qTesla, Picnic) into OpenSSL/OpenSSH and TLS 1.2/1.3. Demonstration shows a hybrid ECDSA P‑256+qTesla certificate and working OpenSSL fork; NewHope performance approaches P‑256, so practical migration is viable.
