Non-ephemeral DH algorithms use static DH public keys included in the authenticating peer's certificate; see [RFC4492] for discussion. In contrast, ephemeral DH algorithms use ephemeral DH public keys sent in the handshake and authenticated by the peer's certificate. Ephemeral and non-ephemeral finite field DH algorithms are called DHE and DH (or…

Diátaxis is a way of thinking about and doing documentation. Help translate Diátaxis into your language. It prescribes approaches to content, architecture and form that emerge from a systematic approach to understanding the needs of documentation users. Diátaxis identifies four distinct needs, and four corresponding forms of documentation - tutorials, how-to guides, technical reference and explanation. It places them in a systematic relationship, and proposes that documentation should itself be organised around the structures of those needs. Diátaxis,…

Imagine buying a brand-new, fancy, premium-grade car. From an automaker with a respected name. Like, say, BMW. This is a machine with some status! Let’s say it costs, oh, $61,500, and you’re paying, what, about $1300 a month? Something like that.
