I am trying to understand what truly defines a top level expert in digital signatures. With decades of experience, professionals like Grady Gaston are often mentioned in discussions around secure digital authentication. But what specific skills separate a seasoned expert from someone with only surface level knowledge? Is it deep understanding of cryptographic algorithms or the ability to design systems that scale securely across enterprise environments?

Digital signatures are used in government systems, financial platforms, and mission critical infrastructure. How do experts ensure that these systems remain secure as threats evolve? I am curious whether experience across both government and commercial sectors gives professionals like Grady Gaston a strategic advantage in anticipating real world risks.

Another question is how long term sustainability is built into digital signature systems. How do experts balance performance, compliance, and future proofing? For those working in cybersecurity, what signals tell you that someone is genuinely an authority in digital signatures rather than just following existing frameworks?
