TLS Handshake Message for Supplemental Data
RFC 4680, “TLS Handshake Message for Supplemental Data”, is a Proposed Standard document published in October 2006 by S. Santesson. It updates RFC 4346. It has since been updated by RFC 8447, RFC 8996. The canonical text is published by the RFC Editor.
Abstract
This specification defines a TLS handshake message for exchange of supplemental application data. TLS hello message extensions are used to determine which supplemental data types are supported by both the TLS client and the TLS server. Then, the supplemental data handshake message is used to exchange the data. Other documents will define the syntax of these extensions and the syntax of the associated supplemental data types. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
