PQC Migration Guide

A structured reference for organisations assessing their exposure to quantum threats. Each component is mapped across three lenses: what cryptographic controls exist today, what post-quantum migration is recommended, and PQStation's strategic perspective on prioritisation and implementation.

Cryptographic assessments reference current algorithm usage — RSA, ECC, AES, ECDSA, TLS variants — against NIST PQC standards (FIPS 203/204/205) and hybrid transition models. Migration guidance addresses key establishment, digital signatures, and long-lived data exposure under harvest-now-decrypt-later threat models, with implementation sequencing grounded in crypto-agility principles and HSM/PKI upgrade constraints.
