A couple of things to note from mr schneider's blog warning...
Fact..until it's published and the method handed out and it's replicated
independently, SHA-1 is NOT broken.
Fact..the people posting here missed a fairly important bit of schneider's
blog-post, and I quote:
>>The paper isn't generally available yet. At this point I can't tell if
the attack is real.
read it again: >>AT THIS POINT I CAN'T TELL IF THE ATTACK IS REAL.
(Translation, there is no proof that the sky is falling. Yes, the
researchers are reputable...but the scientific method of repeatable
results with published methods needs to verifiy it)
Fact: If the paper and method are sound...the sky STILL is not falling
(although it will be raining pretty darned hard)...2^69 operations...to
get a collision...how many hours of current gen cpu cycles?? (some notes
from the blog thread postulate a 4 ghz machine would need 4000
years...4000 CPU 4 ghz ea ...1 year.) Based on the rumors, would I
entrust state secrets to SHA-1? Nope. Digital signature on a dosument
authorizing the use of Nukes against Utah? Nope. Failing that level of
protection requirement, for the time being, of course I would, and will.
