The objective is a tall order. The quantum-resistant cryptographic data needed to transparently publish TLS certificates is roughly 40 times bigger than the classical cryptographic material used today. Today’s X.509 certificates are about 64 bytes in size, and comprise six elliptic curve signatures and two EC public keys. This material can be cracked through the quantum-enabled Shor’s algorithm. Certificates containing the equivalent quantum-resistant cryptographic material are roughly 2.5 kilobytes. All this data must be transmitted when a browser connects to a site.
Despite an ultimatum from Defense Secretary Pete Hegseth, Anthropic said that it can't "in good conscience" comply with a Pentagon edict to remove guardrails on its AI, CEO Dario Amodei wrote in a blog post.
