Tspi_Data_Unbind - Decrypts data that has been bound to a key 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_Data_Unbind(TSS_HENCDATA hEncData, TSS_HKEY hEncKey, UINT32* pulUnboundDataLength, BYTE** prgbUnboundData); DESCRIPTION
Tspi_Data_Unbind decrypts the encrypted data blob exportedfrom the data object used in Tspi_Data_Bind. The encrypted data blob must be im- ported to the object addressed by Tspi_SetAttribData before calling this method. PARAMETERS
hEncData The handle of the data object which contains the encrypted data. hEncKey Handle to the key object addressing the private key which is used to decrypt the data. pulDataLength Receives the length of the data at the parameter prgbUnboundData. prgbUnboundData Receives a pointer to a buffer containing the plaintext data. RETURN CODES
Tspi_Data_Unbind returns TSS_SUCCESS on success, otherwise one of the following values is returned: TSS_E_INVALID_HANDLE hEncData or hEncKey is not a valid handle. TSS_E_INTERNAL_ERROR An internal SW error has been detected. TSS_E_BAD_PARAMETER One or more parameters is bad. TSS_E_INVALID_ENCSCHEME Invalid encryption scheme. TSS_E_ENC_INVALID_LENGTH Invalid length of data to be encypted. TSS_E_ENC_NO_DATA No data to encrypt. TSS_E_ENC_INVALID_TYPE Invalid encryption type. CONFORMING TO

Tspi_Data_Seal(3) TCG Software Stack Developer's Reference Tspi_Data_Seal(3) NAME
Tspi_Data_Seal - encrypt a data blob in a mannar that is only decryptable by Tspi_Data_Unseal on the same system. 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_Data_Seal(TSS_HENCDATA hEncData, TSS_HKEY hEncKey, UINT32 ulDataLength, BYTE* rgbDataToSeal, TSS_HPCRS hPcrComposite); DESCRIPTION
Tspi_Data_Seal encrypts a data blob in a mannar that is only decryptable by Tspi_Data_Unseal on the same system. The data blob is encrypted using a public key operation with the nonmigratable key addressed by the given encryption key object. PARAMETERS
hEncData Handle of the data object which contains the sealed data on successful completion of the command. hEncKey Handle to the key object addressing the nonmigratable key which is used to encrypt the data. ulDataLength The Length (in bytes) of the rgbDataToSeal parameter. rgbDataToSeal Pointer to memory containing the data to be encrypted. hPcrComposite Handle of the PCR Composite object specifying the PCRs which are part of the sealed data blob. Set to NULL, if the encrypted data should only be bound to the system and PCRs are not of interest. RETURN CODES
Tspi_Data_Seal returns TSS_SUCCESS on success, otherwise one of the following values are returned: TSS_E_INVALID_HANDLE - One of the following parameters hEncData, hEncKey, rgbDataToSeal is invalid. TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS. CONFORMING TO
