This method creates an alts_iovec_record_protocol instance, given a gsec_aead_crypter instance, a flag indicating if the created instance will be used at the client or server side, and a flag indicating if the created instance will be used for integrity-only mode or privacy-integrity mode.
The ownership of gsec_aead_crypter instance is transferred to this new object.
- crypter: a gsec_aead_crypter instance used to perform AEAD decryption.
- overflow_size: overflow size of counter in bytes.
- is_client: a flag indicating if the alts_iovec_record_protocol instance will be used at the client or server side.
- is_integrity_only: a flag indicating if the alts_iovec_record_protocol instance will be used for integrity-only or privacy-integrity mode.
- is_protect: a flag indicating if the alts_grpc_record_protocol instance will be used for protect or unprotect.
- rp: an alts_iovec_record_protocol instance to be returned from the method.
- error_details: a buffer containing an error message if the method does not function correctly. It is OK to pass nullptr into error_details.
On success, the method returns GRPC_STATUS_OK. Otherwise, it returns an error status code along with its details specified in error_details (if error_details is not nullptr).
This method performs integrity-only protect operation on a alts_iovec_record_protocol instance, i.e., compute frame header and tag.
The caller needs to allocate the memory for header and tag prior to calling this method.
- rp: an alts_iovec_record_protocol instance.
- unprotected_vec: an iovec array containing unprotected data.
- unprotected_vec_length: the array length of unprotected_vec.
- header: an iovec containing the output frame header.
- tag: an iovec containing the output frame tag.
- error_details: a buffer containing an error message if the method does not function correctly. It is OK to pass nullptr into error_details.
On success, the method returns GRPC_STATUS_OK. Otherwise, it returns an error status code along with its details specified in error_details (if error_details is not nullptr).
This method performs privacy-integrity protect operation on a alts_iovec_record_protocol instance, i.e., compute a protected frame.
The caller needs to allocate the memory for the protected frame prior to calling this method.
- rp: an alts_iovec_record_protocol instance.
- unprotected_vec: an iovec array containing unprotected data.
- unprotected_vec_length: the array length of unprotected_vec.
- protected_frame: an iovec containing the output protected frame.
- error_details: a buffer containing an error message if the method does not function correctly. It is OK to pass nullptr into error_details.
On success, the method returns GRPC_STATUS_OK. Otherwise, it returns an error status code along with its details specified in error_details (if error_details is not nullptr).
This method performs privacy-integrity unprotect operation on a alts_iovec_record_protocol instance given a full protected frame, i.e., compute the unprotected data.
The caller needs to allocated the memory for the unprotected data prior to calling this method.
- rp: an alts_iovec_record_protocol instance.
- header: an iovec containing the frame header.
- protected_vec: an iovec array containing protected data including the tag.
- protected_vec_length: the array length of protected_vec.
- unprotected_data: an iovec containing the output unprotected data.
- error_details: a buffer containing an error message if the method does not function correctly. It is OK to pass nullptr into error_details.
On success, the method returns GRPC_STATUS_OK. Otherwise, it returns an error status code along with its details specified in error_details (if error_details is not nullptr).
