Description

Digital certificate industry veterans Tim Callan and Jason Soroko explore the issues surrounding digital identity, PKI, and cryptographic connections in today's dynamic and evolving computing world. Best practices in digital certificates are continually under pressure from technology trends, new laws and regulations, cryptographic advances, and the evolution of our computing architectures to be more virtual, agile, ubiquitous, and cloud-based. Jason and Tim (and the occasional guest subject matter expert) will help you stay current on developments in this essential technology platform and to understand the whys and wherefores of popular Public Key Infrastructures.

Root Causes 608: The Fragility of Formal Verification

2026/04/22

The reliability of cryptographic algorithms is largely a matter of conjecture based on track record. Proving security is impaired by the difficulty of formal verification, implementation weaknesses, and failure in randomness.

Root Causes 607: PKI That's Hard to Discover

2026/04/20

The first of the five pillars of Certificate Lifecycle Management (CLM) is discovery. While many of your certificates are easily discoverable, some difficult PKI remains.

Root Causes 606: What Is the UK Online Safety Act?

2026/04/17

The UK Online Safety Act intends to force vendors who sell hardware and software to allow the government to scan end-to-end encrypted communication on end devices. We once again marvel at governments seeking to undermine the security of their own citizens.

Root Causes 605: Chrome Declares Its Support for Merkle Tree Certificates (MTC)

2026/04/15

Google has taken a strong position supporting Merkle Tree Certificates (MTC) as the PQC-enabled future for SSL / TLS. We unpack this extremely important position from the WebPKI's most influential organization.

Root Causes 604: Accelerated Timeline for Quantum Computers Breaking ECC in Crypto and Blockchain

2026/04/13

A new paper from Google Quantum AI and others documents a new technique for breaking ECC, particularly the curve protecting crypto currencies, smart contracts, and blockchain. This accelerates post quantum cryptography (PQC) timelines.

Root Causes 603: Cryptographically Relevant Quantum Computing (CRQC) with Only 10,000 Qubits

2026/04/10

New research suggests that a cryptographically relevant quantum computer is achievable with only 10,000 qubits. This was an important contributor to Google moving its PQC target to 2029.

Root Causes 602: Google Moves the PQC Date Forward to 2029

2026/04/08

Google has announced that it is moving its target for full PQC support to 2029. This is a strong statement from one of the most knowledgeable PQC technology companies that the existing 2030 target is too late.

Root Causes 601: The Zombie in the Server Room

2026/04/06

Legacy PKI implementations in the enterprise are holding back technical progress and creating security risk. We discuss reasons why, consequences, and what to do about it.

Root Causes 600: Cryptographic Design Is Not Neutral

2026/04/03

In our previous episode we defined cryptography as the new geopolitics. Now in our 600th episode we follow up to explain how all cryptographic decisions reflect the social, political, and legal viewpoints of the cryptography's designers.

Root Causes 599: Cryptography Is the New Geopolitics

2026/04/01

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.

Root Causes 598: Why Johnny Can't authN in OT

2026/03/30

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.

Root Causes 597: If You Don't Hold the Keys, You Don't Hold the Subpoenas

2026/03/27

Microsoft has publicly stated that it will hand over Bitlocker keys to US law enforcement agencies without requiring a subpoena or court order. These keys can be held by users rather than Microsoft, at their option. We dive into this topic.

Root Causes 596: CLM and Operational Uptime

2026/03/25

We usually think of Certificate Lifecycle Management (CLM) as a security category. But we could equally well categorize it as an operations category that enables uptime. In this episode we make our case.

Root Causes 595: What Is a Digital Parasite?

2026/03/23

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

Root Causes 594: Google's Five PQC Recommendations for Policy Makers

2026/03/18

In a recent blog post Google made five recommendations for policy makers. We walk down the list.
