[OpenWireless Tech] responce to Brad's crypto-fascist conspiracy theorist side

[Todd Freeman]

Looks like your crypto-facist fantasies have been answered.

Also looks like I was exactly right when I said:
Unless you can implement Elliptic curve cypto, openssl does support it, but on redhat/centos you need to recompile openssl for ECDSA and ECDH support, debian/ubuntu comes with it by default now. 

Thanks for being dismissive! Because obviously that is how these things will get fixed.

If that page and <http://lastbit.com/pswcalc.asp> is correct, then assuming they have hardware equivalent to <https://products.butterflylabs.com/homepage/500-gh-s-bitcoin-miner.html>, and you try to scale up the math, then 500TH/s would still theoretically take 14519386921195274 years to crack a 20 character random alphanumeric password (~120 bits of entropy).  By that math, a fourteen character password would fall in 88422 years, and twelve characters would fall in seventeen years.

Personally, with massive multi-petabyte rainbow tables in RAM and improved hardware, I don't think it would take anywhere near that long.  My guess is that NSA already has quantum cryptography equipment that measures on the scale of dozens or hundreds of square miles of computer room floor space, and with quantum crypto all the sort of stuff we have been talking about so far would fall in linear time.


But maybe that's just my paranoid crypto-fascist conspiracy theorist side talking.
