       TSS_RESULT Tspi_Context_GetKeyByPublicInfo(TSS_HCONTEXT     hContext,      TSS_FLAG  persistentStorageType,
                                                  TSS_ALGORITHM_ID algID,         UINT32    ulPublicInfoLength,
                                                  BYTE*            rgbPublicInfo, TSS_HKEY* phKey);

DESCRIPTION

       TSS_Context_GetKeyByPublicInfo  searches the persistent storage for a registered key using  the  provided
       public  key  information  and  creates a key object initalized according to the found data. On successful
       completion of the method a handle to the created new key object is returned.

PARAMETERS

   hContext
       The handle of the context object.

   persistentStorageType
       Flag indicating the persistent storage the key is registered in.

   algId
       This parameter indicates the algorithm of the requested key.

   ulPublicInfoLength
       The length of the public key info provided at the parameter rgbPublicInfo.

   rgbPublicInfo
       The public key info is provided to identify the key to be look for at the  persistent  storage.  In  case
       algID equals to TSS_ALG_RSA this prameter contains the modulus of the public RSA key.

   hKey
       Recieves the handle of the key object representing the key. In case the key hasn't been found, this value
       will be NULL.

RETURN CODES

       Tspi_Context_GetKeyByPublicInfo returns TSS_SUCCESS on success, otherwise one of the following values are
       returned:

       TSS_E_INVALID_HANDLE - hContext is an invalid handle.

       TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.

CONFORMING TO

       Tspi_Context_GetKeyByPublicInfo  conforms  to  the Trusted Computing Group Software Specification version
       1.1 Golden
