Post-Quantum Code Signing: What Developers Need to Know for the Quantum Era
There is a hard deadline for post-quantum code signing: You sign a certificate in 2026 that may still be needed to check the certificate on a device in 2035 that you can’t re-flash. This post covers what PQC signatures are, why RSA/DSA/ECDSA doesn’t work against a CRQC, how code signing is different from SSL, and what AWS, Google, and MS shipped. Inventory paths. Select an algorithm class. Test dual-sign. Follow cert and KMS roadmaps.
