Table 191 defines the public area structure. The Name of the object is nameAlg concatenated with the digest of this structure using nameAlg.

Field Summary

Fields
Modifier and Type	Field and Description
`byte[]`	`authPolicy` optional policy for using this key The policy is computed using the nameAlg of the object.
`TPM_ALG_ID`	`nameAlg` algorithm used for computing the Name of the object NOTE The "+" indicates that the instance of a TPMT_PUBLIC may have a "+" to indicate that the nameAlg may be TPM_ALG_NULL.
`TPMA_OBJECT`	`objectAttributes` attributes that, along with type, determine the manipulations of this object
`TPMU_PUBLIC_PARMS`	`parameters` the algorithm or structure details
`TPMU_PUBLIC_ID`	`unique` the unique identifier of the structure For an asymmetric key, this would be the public key.
