Tenant Secret Lifecycle

A tenant secret is the per-org root from which Shield derives (or wraps) data encryption keys. Its lifecycle operations are UI/REST-only — there is no *.settings-meta.xml for rotating, destroying, or uploading a tenant secret. When a user asks about these, return guidance and point them at Setup or the REST/Tooling API, not a metadata file.

Operations

Operation What it does Surface
Generate Creates a new active tenant secret for a key type Setup → Key Management, or REST
Rotate Generates a new tenant secret; existing data stays readable under prior secrets Setup / REST
Destroy Permanently destroys key material; data encrypted under it becomes unrecoverable Setup (destructive, requires confirmation)
BYOK upload Uploads customer-supplied key material as the tenant secret Setup / REST
Cache-Only callout setup Configures the named credential / callout endpoint the key service is fetched from Setup (Named Credentials)

Rotation semantics

Rotating a tenant secret makes a new secret active; prior secrets are retained as archived so existing ciphertext stays readable. New writes use the active secret. To move existing data onto the new secret, run background encryption (a.k.a. the sync/re-encrypt process) — rotation alone does not re-encrypt existing rows.

For BYOK specifically, the sequence is: rotate to (upload) the new key material, then run background encryption to apply it. Uploading new material does not retroactively re-encrypt existing data on its own.

Destruction semantics

Destroying a tenant secret is irreversible. Any data whose keys derive from that secret and has not been re-encrypted under another active secret becomes permanently unreadable. This is intentional (right-to-be-forgotten / crypto-shredding) but must be surfaced as a hard warning — there is no recovery path.
