s32sdaf-wrap-key
Wrap a plain device key using the smart-card public wrapping key for S32SDAF / Volkano workflows. This workflow uses volkano_utils.exe -cmd wrap_key to produce wrapped material suitable for later regi

GitHubWrap a Plain Key for Later Registration
Wrap a plain key using the smart-card public wrapping key so the result can
later be registered on the card. The grounded command path for this operation
is volkano_utils.exe -cmd wrap_key, not volkano.exe. This is a preparatory
workflow for users who want wrapped output now and will register it later.
Critical rule: ADKP is the only key type that can be registered in plain form. Every non-ADKP key type must be wrapped first before registration.
When to use
Trigger this skill when the user wants to:
- wrap a plain key now but register later ("wrap this key", "prepare wrapped key material", "I have a plain key and need the wrapped result only")
- prepare wrapped key material outside a full wrap-and-register workflow
- verify the difference between a plain key, the smart-card public wrapping key, and the final wrapped key
Do not use it to register the wrapped key, register plain ADKP, delete records,
or guess the semantic key type. If the user wants wrapping followed immediately
by registration, switch to s32sdaf-wrap-and-register. If the input already
appears wrapped, route to s32sdaf-register-key.

Inputs: plain_key (hex), optional public_key (hex), optional
volkano_folder.
Quickstart
- Verify readiness with
statusif the environment is not trusted. - Validate
plain_keyis hex; validatepublic_keyif supplied. - If no trusted
public_key, export it withexecute_action(action="export_wrapkey", params={...}). - Wrap via
execute_action(action="wrap_key", params={...})(inputs:plain_key,public_key, optionalvolkano_folder). - Return the wrapped key as registration-ready material, distinct from the public wrapping key used to create it.
Workflow
- Treat this as a preparatory workflow that does not itself modify card registrations. Distinguish plain key input, public wrapping key, and wrapped output at every step.
- If the user already has a valid public wrapping key, do not force another export.
- Validate hex format before calling the wrap tool. If the input already looks
like wrapped output, stop and redirect to
s32sdaf-register-key- do not wrap twice. - Obtain the public wrapping key via
execute_action(action="export_wrapkey", params={...})when it is not already available and trusted. - Wrap via
execute_action(action="wrap_key", params={...}). The underlying command isvolkano_utils.exe -cmd wrap_key; do not describe it as avolkano.exeoperation. If the wrapper errors in a way that suggests bad command construction, diagnose the wrapper or provide the exactvolkano_utils.execommand shape rather than switching executables. - Return the wrapped output and route onward: registration -> route based on goal below.
Routing:
- Register the wrapped key now ->
s32sdaf-register-key - Combined wrap + register in one go ->
s32sdaf-wrap-and-register
Guardrails
Scope - Preparatory / non-registration. May export the public wrapping key and generate wrapped material; does not modify card registrations.
Destructive actions - None here; the registration mutation happens in a downstream skill. Never wrap a key twice.
Secrets - Treat plain key, public wrapping key, and wrapped output as sensitive; do not echo unnecessarily.
Refuse-and-escalate -
- Missing
plain_key: report it is required; do not continue. - Input already wrapped: redirect to
s32sdaf-register-key; do not re-wrap. - Missing/invalid public wrapping key: export it from the card, or report that wrapping cannot proceed without a valid one.
- Export failure: report card readiness/access issue; recommend
s32sdaf-discovery-and-status. - Wrap failure: report the plain/public key may be invalid; recommend
re-exporting the public wrapping key. If the error indicates missing/malformed
command dispatch, note the expected
volkano_utils.exe -cmd wrap_keypath and treat it as a wrapper/backend problem, not a reason to switch tovolkano.exe. - User wants immediate registration: switch to
s32sdaf-wrap-and-register.
Validation loop
- Confirm the public wrapping key was obtained or reused correctly.
- Confirm the plain key was wrapped successfully.
- Pass criterion: wrapped output is clearly identified as later registration input, and the next workflow is identified when the user wants to continue.
Out of scope
- Registering the wrapped key on the card (see
s32sdaf-register-key). - Registering plain ADKP directly (see
s32sdaf-register-key). - Deleting records; guessing the semantic key type.
