Diffie-Hellman Standards []. There are a number of standards relevant to Diffie-Hellman key agreement. Some of the key ones are: PKCS 3 defines the basic algorithm and data formats to be used.; ANSI X9.42 is a later standard than PKCS 3 and provides further guidance on its use (note OpenSSL does not support ANSI X9.42 in the released versions - support is available in the as yet unreleased 1.0 ...

Diffie-Hellman Another method of exchanging the session key, is by using Diffie-Hellman. Using Diffie-Hellman, the session key is never sent over the network and is therefore never part of the network session data. Variants of Diffie-Hellman There are three main variants of Diffie-Hellman in SSL/TLS.

Nearly all modern TLS implementions support 2048 bit Diffie-Hellman keys. Openssl-based clients, as well as Java 7 & 8 support it by default. Java 6 and below do not support 2048 DH key sizes. An exception like the following will occur when a default Java 6 JRE attempts to connect with TLS and 2048 Diffie-Hellman keys:

Fortunately, the vast majority of these clients do support some newer algorithms, but none that currently overlap with those supported by GitHub. As a result, GitHub will add support for diffie-hellman-group-exchange-sha256 before we remove support for diffie-hellman-group1-sha1 and diffie-hellman …Author: Patrick Toomey

Today, news broke of Logjam, an attack on TLS connections using Diffie-Hellman ciphersuites. To protect OpenSSL-based clients, we’re increasing the minimum accepted DH key size to 768 bits immediately in the next release, and to 1024 bits soon after.

Connections with keys shorter than 1024 bits may already be in trouble today. (Note: you need OpenSSL 1.0.2. Earlier versions of the client do not display this information.) (If the connections fails straight away, then the server does not support ephemeral Diffie-Hellman ("EDH" in OpenSSL-speak, "DHE" elsewhere) at all and you're safe from ...
