Did I imply you did? I simply said I never see a "pro AI" mob, only an "anti AI" mob.
Let's flip it, then Is the "anti AI mob" in the room with us right now? If not, why did you feel the need to lament it?
Basically 2 days on a consumer GPU to crack a 512 bit cert. The thing is much of the traffic back then did not use ephemeral keys. Most of it wasn't even encrypted at all! But about a decade later, it became normal to encrypt everything. I do wonder which governments around the world are just waiting to crack anonymous political speech by recording and saving for later when decryption can happen.
> which governments around the world are just waiting to crack anonymous political speech by recording and saving for later Probably not too many, because anonymous political speech from 10+ years ago isn't that interesting. Punishing people a decade after the fact isn't very effective for anything.
It sends a very clear message: even if it takes a decade, we will find you and punish you.

A while back I helped a friend (read: dumped a bunch of compute power into it) brute force the SSL keys for Sega's "Phantasy Star Online" Dreamcast game. They used a similar kind of custom (and flawed) TLS implementation in their game(s) which allowed signing new certificates after brute forcing. The benefit to this is that users can now play these games without needing to burn a new CD with either the SSL certs swap…
For what it's worth, this comment was better than the article... When you outsource to the slop machine, you don't have anything interesting to say (usually).

Activists 10 years ago are probably still linked to interesting people the government wants to survey though, even if they are maybe less active now
The cost per bit is a doubling in time. So factoring a 512 RSA, compared to a 1024 RSA is significantly cheaper. The OP used contemporary hardware to do this. so, we'd have to ask if the orders of magnitude improvement in tech (QC aside) would permit 1024 in tractable time. I tend to no, but I appreciate there are other points of view. And of course, the belief that one day we can apply Shor with success exists. At w…
Doubling per bit is for symmetric encryption, where no attack better than brute force is known. RSA can be attacked using much faster techniques than brute force.
I know that factoring (which attacks RSA) is sub-exponential, and I know that implementations of RSA (bad choices of primes, timing attacks, etc) can have weaknesses ... I'm just interested as to whether you have something else in mind.
Thx.

Can you point at some papers or articles that talk about attacks specifically on RSA? I've done a search and have a few references, but I'd be interested to know if you have any particular examples in mind.
