Hello There! As you might know, NIST has acknowledged that large-scale quantum computers will threaten the security of its approved public-key algorithms. In particular, NIST-approved digital signature schemes, key agreement using Diffie-Hellman (DH) and Menezes-Qu-Vanstone (MQV), and key agreement and key transport using Rivest–Shamir–Adleman (RSA) may need to be replaced with secure quantum-resistant (or “post-quantum”) […]
