TSS_RESULT Tspi_Data_Bind(TSS_HENCDATA hEncData, TSS_HKEY hEncKey,
UINT32 ulDataLength, BYTE* rgbDataToBind);
DESCRIPTION
Tspi_Data_Bind encrypts a data blob in a manner that is decryptable by Tspi_Data_Unbind. The data blob is encrypted using a public key operation with the key addressed by the given encryption key object. To bind data that is larger than the RSA public key modulus is the responsibility of the caller to perform the blocking and subsequent combination of data. The bound data blob is stored in the data object addressed by hEncData and can be exported from the object by Tspi_GetAttribData. The caller of this function should perform validations that the public key presented to it is from a valid TPM.PARAMETERS
hEncData
The handle of the data object which contains the encrypted data on successful completion of the command.hEncKey
Handle to the key object addressing the public key which is used to encrypt the data.ulDataLength
Indicates the length of the data provided at the parameter rgbDataToBind.rgbDataToBind
A pointer to the data to be encrypted.RETURN CODES
Tspi_Data_Bind returns TSS_SUCCESS on success, otherwise one of the following values is returned:- TSS_E_INVALID_HANDLE
- hHash 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.
