Root Causes: A PKI and Security Podcast

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 u...

Episodes

Root Causes 575: Shortening Certificate Term - All the Dates 02.02.2026

Everybody knows about March 15 and the drop in maximum public TLS certificate term to 200 days. But that only scratches the surface on key dates with this maximum term reduction. Join us as we go over "all the dates" for TLS maximum term reduction.

Root Causes 574: 2025 Predictions Scorecard - Part 2 30.01.2026

We score our 2025 predictions in this second of two parts.

Root Causes 573: 2025 Predictions Scorecard - Part 1 28.01.2026

Every new year we make predictions for the year to come, and every year we go back and see how we did. This is the first of two parts scoring our 2025 predictions.

Root Causes 572: Quality of Entropy 26.01.2026

We discuss the idea that not all cryptographic entropy is equally "random" and potential consequences.

Root Causes 571: Will There Ever Be a Cryptographically Relevant Quantum Computer? 23.01.2026

We discuss the idea that it might be impossible to actually create a cryptographically relevant quantum computer and weigh in on this idea.

Root Causes 570: PQC Readiness at the Boardroom Level 21.01.2026

Repeat guest Chris McGrath shares what enterprises need to be doing now to stay on track for the NIST PQC deadline in 2030.

Root Causes 569: New Regulations Are Changing the PKI Landscape 19.01.2026

Repeat guest Chris McGrath joins us to discuss how increasingly strict regulations are requiring increased rigor, visibility, and auditability for enterprise digital certificates and PKI.

Root Causes 568: Upping Your Certificate Game for Better Security 16.01.2026

Senior cyber security advisor Chris McGrath joins us to discuss redefining digital certificates and their role in your organizational security profile, increasing regulation of certificates, and how enterprises can up their certificate game.

Root Causes 567: Top 10 PQC Laggards in the Enterprise 14.01.2026

We name the ten enterprise environments and use cases that are most likely to be late adopters of post quantum cryptography (PQC).

Root Causes 566: Time Is a Security Primitive 12.01.2026

We discuss the foundational importance of time in PKI and security in general. This includes when things happen, the order in which things happen, and attacks based on time-spoofing. We drill down on certificates, roots, timestamping, Certificate Transparency, patching, audits, and PQC.

Root Causes 565: Our Response to QWAC Arguments - Part 3 08.01.2026

In our concluding episode on the topic, we scrutinize arguments made for and against QWACs, this time focused on "compliance and interoperability."

Root Causes 563: Our Response to QWAC Arguments - Part 1 05.01.2026

As a follow up to our episode 546, we break down the first of three sets of arguments about QWACs and examine their level of validity.

Root Causes 564: Our Response to QWAC Arguments - Part 2 05.01.2026

In our second of three episodes on the topic, we scrutinize arguments made for and against QWACs, this time focused on "governance and sovereignty."

Root Causes 562 : What Is a Side Oracle Attack? 30.12.2025

You may have heard of side channel attacks. Now Jason explains what a side oracle attack is and how a side oracle attack in conjunction with AI could be effective against the HQC or Falcon PQC algorithms.

Root Causes 561: What Is Classic McEliece? 23.12.2025

One of the NIST Round 3 PQC finalists that was never selected or eliminated is Classic McEliece. In this episode we explain in non-math terms how this algorithm works.

Root Causes 560: AI in 1000 Days - Small Language Models 18.12.2025

Continuing our examination of AI in 1000 days, we discuss the use of finely tuned small language models for highly specific use cases.

Root Causes 559: AI in 1000 days - Content Quality 16.12.2025

We discuss what happens when the quality gap between AI-generated and human-generated content drops to zero. We explore the consequences of this inevitable outcome.

Root Causes 558: AI in 1000 days - Human-in-the-loop Economy 15.12.2025

In our ongoing series on what AI will look like in 1000 days, we discuss the spread of a new business process, where AIs do the bulk of the work while humans sit in the loop for certain specific tasks and roles.

Root Causes 557: Top 5 PQC Laggards 12.12.2025

Following up on our list of top 5 PQC vanguards, in this episode we detail the top 5 PQC laggards.

Root Causes 556: Top 5 PQC Vanguards 10.12.2025

We describe the top five technology categories that are on the vanguard of driving PQC adoption. We describe what these categories have in common and how that results in early adoption of post quantum cryptography.

Root Causes 555: Perpretrators of Rogue Certificates 08.12.2025

We detail the top ten groups inside the organization who introduce rogue certificates into IT organizations.

Root Causes 554: Disentangling Quantum 05.12.2025

Tech watchers tend to conflate the many quantum technologies under development right now. In this episode we go through these technologies and explain how they connect.
