3.6.10 Extensions and Supplemental Data

It is possible to transfer supplemental data during the TLS handshake, following [RFC4680]. This is for "custom" protocol modifications for applications which may want to transfer additional data (e.g. additional authentication messages). Such an exchange requires a custom extension to be registered. The provided API for this functionality is low-level and described in TLS Extension Handling.
