TPM_20_E_PARENT
TPM_20_E_PARENT maps to TPM_RC_PARENT. The supplied handle does not represent a valid parent for the requested object operation. This is more specific than a malformed handle: the handle can exist but lack the required parent role, type, or usable attributes.
What to inspect
- Read the candidate parent public area and verify that its object type and attributes support the intended child operation.
- Check that the parent belongs to the expected hierarchy and is loaded in the same TPM context as the child data.
- For import or load workflows, keep the parent public data paired with the wrapped private data that was prepared for it.
