This PR resolves a bug introduced to KnownName handling and introduces a struct tag for commands that allow for the Name to be the Empty Buffer, namely TPM2_SequenceUpdate and TPM2_SequenceComplete.

  • Add tests for multiple transient objects in an HMAC sequence
  • Handle special case for sequence object handle Name fields
  • Relax HmacStart.Handle type from AuthHandle to handle
  • Fix prior RSA test that silently succeeded due to KnownName() bug

Fixes #370
