In our previous episode we defined cryptography as the new geopolitics.  We follow up to explain how all cryptographic decisions reflect social, political, and legal viewpoints of the cryptography's designers.

In the last decade or so, nations around the world have become keenly determined to use cryptography for their own legal, economic, and military advantage. We explore this concept.

A recent CISA report declares that the nation's OT infrastructure is incapable of keeping up with the crypto agility and certificate management needs that modern security demands. We examine this finding.

Microsoft has publicly stated that it will hand over Bitlocker keys to US law enforcement agencies without requiring a subpoena or court order.

We usually think of Certificate Lifecycle Management (CLM) as a security category. But we could equally well call it an operations category that enables uptime.

We introduce the concept of a "digital parasite," explaining why this attack philosophy appears to be on the rise.

CISA (Cybersecurity and Infrastructure Security Agency) has released new guidance about post-quantum cryptography in critical infrastructure, including some sobering warnings.

CAA records exist to restrict issuing CAs for a given domain to as few as one CA. But what happens when the CAA record outlives the CA?
