    Root Causes 608: The Fragility of Formal Verification
    Apr 22 2026
    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
    Apr 20 2026
    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?
    Apr 17 2026
    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.
