What is acceptable today will be deprecated in a few years. It is difficult to keep up. Agreed. Modern cryptography is one of the relatively few things that uses the large amount of bandwidth of modern CPUs. It's possible to run older versions of OpenBSD on 30+ year old DEC minicomputers, for example. It was dropped only because Theo de Raadt couldn't get modern VAXstation hardware to compile it on. I tried to donate a VAXstation 4000/90 to the project when I emigrated -- Red Hat was going to ship it to Canada from the UK for me. De Raadt changed his mind when he learned it wasn't the fastest model, and Red Hat Farnborough lost the machine. 😡 Anyway, making new SSH keys on a VAX took as much as a couple of *days* in some instances. -- Liam Proven ~ Profile: https://about.me/liamproven Email: lpro...@cix.co.uk ~ gMail/gTalk/FB: lpro...@gmail.com Twitter/LinkedIn: lproven ~ Skype: liamproven UK: (+44) 7939-087884 ~ Czech [+ WhatsApp/Telegram/Signal]: (+420) 702-829-053
