Telnet service has long been a standard Internet protocol. However, a
standard way of ensuring confidentiality and integrity of Telnet
sessions has been lacking. This document proposes a standard method
for Telnet clients and servers to use the Transport Layer Security
(TLS) protocol. It describes how two Telnet participants can decide
whether or not to attempt TLS negotiation, and how the two
participants should process authentication credentials exchanged as a
part of TLS startup.
Working Group Summary
It should be noted that the START-TLS document describes a protocol
that passed a Working Group Last Call in the TN3270 WG; however, it
was never submitted to the IESG.
The protocol is implemented in all modern day TN3270 and TN5250
This document was reviewed by Russ Housley for the IESG.
