TLS is the protocol that secures virtually every internet connection - HTTPS websites, API calls, mobile apps talking to servers. TLS 1.3, the current version, uses classical public-key cryptography for key exchange (typically ECDH) and authentication (RSA or ECDSA signatures). Quantum computers break both. The migration to post-quantum TLS is enormous in scope but well-defined in approach. IETF has standardized hybrid ciphersuites that use both classical and post-quantum key exchange - X25519 plus CRYSTALS-Kyber, providing security even if one algorithm is weak. Browser vendors (Chrome, Firefox, Safari) are implementing these hybrids. Server software (OpenSSL, BoringSSL) is adding PQC support. Certificate authorities are testing post-quantum certificates. The timeline: hybrid deployment 2024-2027, pure post-quantum 2030-2035. The challenge is performance and compatibility - Kyber keys are larger than ECC keys, signatures take longer, and legacy systems need updates. But this is happening: Google is testing PQC in Chrome, Cloudflare is running PQC experiments, AWS supports PQC ciphersuites.
TLS protects an estimated 95%+ of internet traffic. Migrating it to post-quantum is migrating the internet itself. This isn't optional - when quantum computers arrive, unprotected TLS becomes transparent to adversaries. Every password, every credit card number, every business communication becomes readable. The migration must complete before quantum computers achieve cryptographic capability.
For enterprises running web applications, APIs, mobile backends - basically any internet service - post-quantum TLS migration is mandatory. It requires updating server configurations, testing compatibility with clients, updating client libraries, rotating certificates to include PQC signatures, and monitoring for problems. Organizations should start testing hybrid ciphersuites now to identify incompatibilities before they become urgent.
