DESCRIPTION

25       TSS_Context_GetKeyByPublicInfo  searches the persistent storage  for  a
26       registered  key using the provided public key information and creates a
27       key object initalized according to the found data. On  successful  com‐
28       pletion  of  the  method  a handle to the created new key object is re‐
29       turned.
30

PARAMETERS

32   hContext
33       The handle of the context object.
34
35   persistentStorageType
36       Flag indicating the persistent storage the key is registered in.
37
38   algId
39       This parameter indicates the algorithm of the requested key.
40
41   ulPublicInfoLength
42       The length of the public key info provided  at  the  parameter  rgbPub‐
43       licInfo.
44
45   rgbPublicInfo
46       The  public  key info is provided to identify the key to be look for at
47       the persistent storage. In case algID equals to TSS_ALG_RSA this prame‐
48       ter contains the modulus of the public RSA key.
49
50   hKey
51       Recieves the handle of the key object representing the key. In case the
52       key hasn't been found, this value will be NULL.
53

RETURN CODES

55       Tspi_Context_GetKeyByPublicInfo returns TSS_SUCCESS on success,  other‐
56       wise one of the following values are returned:
57
58       TSS_E_INVALID_HANDLE - hContext is an invalid handle.
59
60       TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
61

CONFORMING TO

63       Tspi_Context_GetKeyByPublicInfo conforms to the Trusted Computing Group
64       Software Specification version 1.1 Golden
