Mixmaster uses 1024bit RSA keys, and so does Tor. Isn't it time to move to
at least 2048bits? Hardly anybody uses 1024bits for anything these days.
Why are we?
I wouldn't get too panicked just yet. Each additional bit roughly doubles
the factoring time, so a 641 bit key would be 10 months, 642 = 20 months,
643 = 40 months... 1024 = something like 1.00E+120 months (a guesstimate,
check the math).
I suppose it's all about how long you want your data to be safe. There's
no such thing as a "forever" cypher unless you consider the OTP, but
they're impractical in most real life applications. So every common
encryption scheme is a compromise. For real time communications like Tor
where information generally looses value quickly, a "buffer" of a few
million years is more than sufficient for now I'd say. ;)
Not that it doesn't bear watching mind you. Computing power can double in
a year, and costs per calculation can drop dramatically. It's always good
to be aware of the state of things, but it's important not to shift into
"sky is falling" mode every time someone makes another step forward. It
just means things are evolving as expected. No surprises. It's assumed
that keys of a given size will become less secure over time, and any
anomaly in that time line would be a red flag. Even if the anomaly were
larger keys *not* being factored. Worst case scenario, such a thing might
indicate a flaw in the methods we use to factor, and make all previous
results invalid... place us in a state where we have no *clue* about the
security of our encryption algorithms. :(

You're aware that it is Eelbash that you are replying to right?
So please make an exception for floods in this newsgroup and block them. I do
not care about other newsgroups because Freedom of Speech is needed but in this
newsgroup it reflects very very badly on remailers so please block the floods.
Which is just foolish and _extremely_ hypocritical
Please block the floods.
Please block your keyboard and get a life
