Root Causes 585: The Cryptographic Inventory Manifesto
We all love a good manifesto! Jason spells out the ten principles of the Cryptographic Inventory Manifesto, and we discuss.
Root Causes 584: Mapping DORA to CLM
We look at the new European DORA and NIS2 regulations and how Certificate Lifecycle Management is a key requirement to meet these requirements. You will be surprised how explicit these requirements…
Root Causes 583: AI Versus ECC P 256
In an innovative application, an AI has been used to find private keys for ECC (Elliptic Curve Cryptography) P 256. We explain how.
Root Causes 582: New Research Drastically Cuts Number of Qubits for Cryptographic Relevance
New research indicates that the number of qubits necessary to achieve cryptographic relevance has reduced by two orders of magnitude. We cover this breaking news and its implications.
Root Causes 581: A Timeline for Deprecation of Manual DCV Methods
By CABF ballot all manual methods of Domain Control Validation (DCV) will be deprecated by 2028. We explain which methods are due for deprecation and when.
Root Causes 580: Top Use Cases for Hybrid Certificates
We go over the qualities in abstract of a use case that strongly invites the use of hybrid certificates and then run down a list of specific use cases that meet these criteria. This includes OT…
Root Causes 579: Make Cryptography Boring Again
In this episode Jason declares that we must make cryptography boring again. We get into what that means and why it matters.
Root Causes 578: 200 Days Won't Actually Be 200 Days
We have seen much talk of the upcoming drop of maximum TLS term to 200 days, followed by 100 days, and eventually down to 47 days. It happens that all those numbers are too large and the actual…
Root Causes 577: All the Stuff That's Coming in March
March 2026 is due to be the most eventful month in the history of the WebPKI. Join us as we go over all the many changes coming next month.
Root Causes 576: Jeffries Dumps Bitcoin Due to the Quantum Threat
A large investment firm divests from Bitcoin for fear of the quantum threat.
Root Causes 575: Shortening Certificate Term - All the Dates
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…
Root Causes 574: 2025 Predictions Scorecard - Part 2
We score our 2025 predictions in this second of two parts.
Root Causes 573: 2025 Predictions Scorecard - Part 1
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
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?
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
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
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
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…
Root Causes 567: Top 10 PQC Laggards in the Enterprise
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
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…
