Deprecating Secure Sockets Layer Version 3.0

Overview

RFC 7568, “Deprecating Secure Sockets Layer Version 3.0”, is a Proposed Standard document published in June 2015 by R. Barnes, M. Thomson, A. Pironti, A. Langley. It updates RFC 5246. It has since been updated by RFC 8996. The canonical text is published by the RFC Editor.

Abstract

The Secure Sockets Layer version 3.0 (SSLv3), as specified in RFC 6101, is not sufficiently secure. This document requires that SSLv3 not be used. The replacement versions, in particular, Transport Layer Security (TLS) 1.2 (RFC 5246), are considerably more secure and capable protocols.

This document updates the backward compatibility section of RFC 5246 and its predecessors to prohibit fallback to SSLv3.

Abstract as published in the RFC, via rfc-editor.org.

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.
