Summary
- Encryption protects data only while keys, identities and recovery channels remain controlled.
- Rotation, revocation, backup and jurisdiction should be tested before sensitive data is committed.
Data may be encrypted in transit, at rest and sometimes during processing, but every layer creates key-handling decisions. A key stored beside the protected data, an administrator with unchecked access or a recovery process that nobody has tested can defeat the design. Organisations should map who can decrypt, where keys reside, how they rotate, and what happens when a provider or employee disappears. The next proof is a recovery-and-revocation drill, not a claim about cipher strength.
