NAME

       Tspi_Context_GetKeyByPublicInfo - search the persistent storage for a registered key using the provided public key information

SYNOPSIS

       #include <tss/tcpa_defines.h>
       #include <tss/tcpa_typedef.h>
       #include <tss/tcpa_struct.h>

       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  re-
       turned.

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
