Tspi_Context_GetKeyTCGuSoftware(Stack DeveloTspi_Context_GetKeyByPublicInfo(3)

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

SYNOPSIS
       #include <tss/platform.h>
       #include <tss/tcpa_defines.h>
       #include <tss/tcpa_typedef.h>
       #include <tss/tcpa_struct.h>
       #include <tss/tss_typedef.h>
       #include <tss/tss_structs.h>
       #include <tss/tspi.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  com‐
       pletion	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  rgbPub‐
       licInfo.

   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 prame‐
       ter 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,	other‐
       wise 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
