By Christos Kasparis, EnSilica EETimes (May 15, 2024) The rise of quanum computing paints a significant challenge for the cryptography we rely on today. The modern encryption standards we currently use to safeguard sensitive data and communications, such as DSA, public key RSA and those based on elliptic curves, will eventually be broken by
The impact of quantum algorithms on different cryptographic techniques and what can be done about it.

Certificates and public key infrastructure (PKI) are hard. No shit, right? I know a lot of smart people who''ve avoided this particular rabbit hole. Eventually, I was forced to learn this stuff because of what it enables: PKI lets you define a system cryptographically. It''s universal and vendor-neutral yet poorly documented. This is the missing manual.
