What it means
It connects data states, identities, protocols, hardware, certificates, key custody, recovery, monitoring, and lifecycle obligations into one coherent design.
Why it matters
Strong algorithms can still fail when keys are mishandled, trust boundaries are unclear, or migration and recovery were never designed.
Practical focus
- Map protected data, trust relationships, and cryptographic purposes
- Separate key roles, custody, and environments
- Design rotation, revocation, backup, recovery, and destruction
- Plan for algorithm and platform migration
Common mistakes
- Selecting algorithms without a key-management design
- Using one key for unrelated purposes
- Ignoring certificate and trust-anchor lifecycle
- Treating cryptography as a product feature rather than a system dependency
