25 Tspi_Data_Seal encrypts a data blob in a mannar that is only decrypt‐
26 able by Tspi_Data_Unseal on the same system. The data blob is encrypted
27 using a public key operation with the nonmigratable key addressed by
28 the given encryption key object.
29
31 hEncData
32 Handle of the data object which contains the sealed data on successful
33 completion of the command.
34
35 hEncKey
36 Handle to the key object addressing the nonmigratable key which is used
37 to encrypt the data.
38
39 ulDataLength
40 The Length (in bytes) of the rgbDataToSeal parameter.
41
42 rgbDataToSeal
43 Pointer to memory containing the data to be encrypted.
44
45 hPcrComposite
46 Handle of the PCR Composite object specifying the PCRs which are part
47 of the sealed data blob. Set to NULL, if the encrypted data should only
48 be bound to the system and PCRs are not of interest.
49
51 Tspi_Data_Seal returns TSS_SUCCESS on success, otherwise one of the
52 following values are returned:
53
54 TSS_E_INVALID_HANDLE - One of the following parameters hEncData, hEncK‐
55 ey, rgbDataToSeal is invalid.
56
57 TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
