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_Unbind conforms to the Trusted Computing Group Software Specification version 1.1 Golden SEE ALSO

Tspi_Context_LoadKeyByBlob - load a key into the TPM using the key's blob. 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_Context_LoadKeyByBlob(TSS_HCONTEXT hContext, TSS_HKEY hUnwrappingKey, UINT32 ulBlobLength, BYTE* rgbBlobData, TSS_HKEY* phKey); DESCRIPTION
Tspi_Context_LoadKeyByBlob creates a key based on the information gotten by the key blob. It then loads the key into the TPM, which unwraps the key blob by using the key associated with hUnwrappingKey. The key blob addressed by hUnwrappingKey must have been already loaded into the TPM. This function returns a handle to the created key object. PARAMETERS
hContext The hContext parameter is the handle of the context object. hUnwrappingKey The hUnwrappingKey parameter is the handle of the key object which should be used to unwrap the key information associated with rgbBlobDa- ta. rgbBlobData The rgbBlobData parameter is the wrapped key to load. phKey The phKey parameter receives the handle of the key object representing the loaded key. RETURN CODES
Tspi_Context_LoadKeyByBlob returns TSS_SUCCESS on success, otherwise one of the following values is returned: TSS_E_INVALID_HANDLE hContext 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. CONFORMING TO
