So, I saw this here at Farquhar Street at 14:55EST, jumped in the shower,
thus missing the train 13:20 train at Rozzy Square :-), instead took the
bus, and then the T, and got to MIT's New Funny-Looking Building about
16:40 or so, and saw the last few slides, asking the first, and only,
question, because the grad-students shot out of there at relativistic
velocity, probably so they wouldn't miss their dinner, or something...
The upshot, to me, was that 1024-bit RSA keys are, for Nobody Special
Anywhere, probably as DED as DES, for certain keys but probably not all
without way too much money, but that things start to go sideways for this
box somewhere south of 2kbit keysize, and so this is not TEOTWAWKI,
key-wise.
"Unless someone comes up with in algorithmic improvement." Of course. :-).
Cheers,

Who went, obviously, to poke him about Micromint and hash-collisions, for
fun, and who *did* have fun, as a result, in a dead-horse-beating kind of
way...
