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 CODESTspi_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.
