TPM2_CreateLoaded()

This command creates a key object and loads it. The object can be a primary key, in which case TPM2_CreateLoaded() behaves just like TPM2_CreatePrimary(). Or the object can be ordinary or derived.

The created object can then be loaded with TPM2_Load().

To decide whether to use TPM2_CreateLoaded(), TPM2_Create(), or TPM2_CreatePrimary() refer to table 28 in section 2.7 of the TCG TPM Library part 1: Architecture.

If you need to TPM2_CertifyCreation() that a TPM created some object, you must use TPM2_CreatePrimary() or TPM2_Create().

If you need to seal the object to a PCR selection, you must use TPM2_CreatePrimary() or TPM2_Create().

If you need to create a derived object, you must use TPM2_CreateLoaded().
