PKI and certificate operations
Clarifying ownership, policy, renewal, exception handling and the evidence that shows a certificate lifecycle is working as intended.
Where does operational responsibility become unclear?Digital trust · PKI · cryptographic governance
Making digital trust visible, governable and resilient.
I’m Ayodele (Sodolu) Coker. I work across public key infrastructure, certificate operations, cryptographic change and practical technology—turning complex trust problems into clearer decisions, accountable controls and useful evidence.
Technology matters. Ownership, policy and operational evidence make it trustworthy.

Areas of practice
Where I focus
I’m interested in the point where architecture meets day-to-day responsibility: who owns a control, how it behaves under change, and what evidence proves it worked.
Cryptographic inventory and PQC readiness
Making algorithms, keys, certificates, protocols, libraries, data lifetimes and system owners visible before migration decisions are made.
Which dependencies would make a cryptographic change difficult?Code signing and machine identity
Exploring how identity, provenance, policy and approval should govern software and increasingly autonomous systems.
What evidence should exist before trust is granted?Selected thinking
Writing from the work
Notes on PKI, cryptographic change, AI governance and the practical disciplines that make trust systems easier to operate.
Certificate Automation Is Not a Product Problem The Operating Rules Behind Reliable Renewal
Why ACME, APIs and lifecycle platforms still need clear ownership, policy, deployment evidence and rollback paths—and how to choose a safe first automation pilot.

Products and experiments
Ideas made tangible
Small, practical products that reflect the same priorities: clear limits, useful feedback and respect for the person using them.
DRAControlled testing
Drive Rescue Assistant
A local-first, extraction-first rescue tool that inspects readable files and copies selected data to a separate destination without repairing, formatting or deleting from the source.

CalmTide
A quiet guided-breathing app with adjustable phases, calm tide visuals, optional local reminders and no account required.
Beyond the technology
The person inside the practice
Technical work is only part of the story. These are the things that steady me, slow the pace and give the work its human context.
Christian faith
My faith shapes how I try to live, work and treat others. It reminds me that character matters as much as achievement.

Soft jazz and gospel
Music gives me room to think, make and unwind. I’m drawn to warmth, restraint and an unhurried conversation.
