id seal unseal

seal oe_result_t(* _oe_seal_plugin_definition::seal) (const oe_seal_setting_t *settings, size_t settings_count, const uint8_t *plaintext, size_t plaintext_size, const uint8_t *additional_data, size_t additional_data_size, uint8_t **blob, size_t *blob_size) Callback function to be called by oe_seal() when sealing a blob. Parameters [in] settings The array of oe_seal_setting_t structs passed to oe_seal(). If not NULL, oe_seal() guarantees that the whole settings array resides in enclave memory. [in] settings_count Number of elements in settings. [in] plaintext Optional data to be encrypted. If not NULL, oe_seal() guarantees the whole plaintext buffer resides in enclave memory. [in] plaintext_size Size of plaintext. [in] additional_data Optional additional data to be included in authentication (MAC calculation). If not NULL, oe_seal() guarantees that the whole additional_data buffer resides in enclave memory. [in] additional_data_size Size of additional_data. [out] blob Receives the address of the resulted sealed blob. Freed by oe_free(). This parameter will never be NULL. [out] blob_size Receives the size of blob on success. This parameter will never be NULL. Return values OE_OK The operation succeeded. OE_INVALID_PARAMETER At least one seal setting was invalid. OE_UNSUPPORTED Unrecognized seal settings. OE_OUT_OF_MEMORY Memory allocation failed.
