       Tspi_Data_Bind - Encrypts a data blob

SYNOPSIS

       #include <tss/tcpa_typedef.h>
       #include <tss/tcpa_struct.h>

       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.
