TPM_E_KEY_USAGE_POLICY_INVALID
TPM_E_KEY_USAGE_POLICY_INVALID means a key usage policy was found but its contents are not valid for the current TPM-backed key operation.
What to check
- Validate the policy structure, key usage, algorithm, and binding requirements used when the policy was created.
- Check whether the policy refers to stale PCR values, an obsolete key name, or an unsupported property combination.
- For centrally provisioned keys, verify that the policy version matches the installed client and TPM firmware.
