Telnet Encryption: DES3 64 bit Cipher Feedback
Overview
RFC 2947, “Telnet Encryption: DES3 64 bit Cipher Feedback”, is a Proposed Standard document published in September 2000 by J. Altman. The canonical text is published by the RFC Editor.
Abstract
This document specifies how to use the Triple-DES (data encryption standard) encryption algorithm in cipher feedback mode with the telnet encryption option. [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.
