Contents
Conforming To
Tspi_Context_GetKeyByPublicInfo conforms to the Trusted Computing Group Software Specification version
1.1 Golden
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.
Name
Tspi_Context_GetKeyByPublicInfo - search the persistent storage for a registered key using the provided
public key information
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 alβ
gID 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.
