We've defined three of the available numbers: 2.23.133.10.1.3 TPM Loadable key. This is an asymmetric key (Usually RSA2048 or Elliptic Curve) which can be imported by a TPM2_Load() operation. 2.23.133.10.1.4 TPM Importable Key. This is an asymmetric key (Usually RSA2048 or Elliptic Curve) which can be imported by a TPM2_Import() operation. Both loadable and importable keys are specific to a given TPM, the difference is that a loadable key is wrapped with the symmetric secret, so must have been created by the TPM itself. An importable key is wrapped with a DH shared secret, and may be created without access to the TPM provided you know the public part of the parent key. 2.23.133.10.1.5 TPM Sealed Data. This is a set of data (up to 128 bytes) which is sealed by the TPM. It usually represents a symmetric key and must be unsealed before use. The ASN.1 binary key form starts of with this OID as the first element of a sequence, giving the binary form a unique recognizable identity marker regardless of encoding.
