NAME

       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>
       #include <tss/tss_typedef.h>
       #include <tss/tss_structs.h>
       #include <tss/tspi.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 op-
       eration with the key addressed by the given encryption key object. To bind data that is larger than the RSA public key modulus is  the  re-
       sponsibility of the caller to perform the blocking and subsequent combination of data. The bound data blob is stored in the data object ad-
       dressed 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.

CONFORMING TO

       Tspi_Data_Bind conforms to the Trusted Computing Group Software Specification version 1.1 Golden

NAME

       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.
