TSS_RESULT Tspi_Data_Bind(TSS_HENCDATA hEncData,     TSS_HKEY hEncKey,

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.

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.
