Hardware, Embedded Systems "But a powerful new type of computer that is about to be commercially deployed by a major American military contractor is taking computing into the strange, subatomic realm of quantum mechanics. In that infinitesimal neighborhood, common sense logic no longer seems to apply. A one can be a one, or it can be a one and a zero and everything in between - all at the same time. [...] Now, Lockheed Martin - which bought an early version of such a computer from the Canadian company D-Wave Systems two years ago - is confident enough in the technology to upgrade it to commercial scale, becoming the first company to use quantum computing as part of its business." I always get a bit skeptical whenever I hear the words 'quantum computing', but according to NewScientist, this is pretty legit.

If you're using an SSH version that supports it, use an ECDSA key. ECDSA is quantumproof.

That's fine, no great, but the general public doesn't use it. They use HTTPS, maybe POP3S or IMAPS. Or even an IPSEC- or SSL VPN.

Over 25% of the top 200.000 'secure websites' still have SSL2 support enabled, even though it has been know to be insecure since 1995 or 1996:

I doubt any software comes installed with SSL2 enabled by default. So that means that 25% of the people who configure the top 200.000 'secure websites' don't know what they are doing. That is pretty insane.

I also doubt you can find anyone deploying IPSEC VPN in a corporate environment that even knows what Perfect forward secrecy or elliptic curve is and is using an IPSEC gateway that actually supports it.

EDIT/UPDATE correction: at least Windows 2008 servers have SSLv2 enabled by default. So maybe others too. Do we still need it for compatibility, I hope not.
