       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
