       Tspi_Data_Bind - Encrypts a data blob

SYNOPSIS

       #include <tss/platform.h>
       #include <tss/tcpa_defines.h>
       #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.
