Do you really think a school will allow that, though, especially if it takes an intense amount of ressources, hindering people who use the computers for projects?

I still wouldn't think that a whole school district would let you borrow every single computer. I guess you could try though. They would probably say no, because they would think it would just clutter up their system and get in their way

I was thinking summertime.

Plus, DJ, these computers can be turned on and off from any of the admin computers. Not kidding. my Comp. Teacher showed me one time. They all turn on and off automatically at the end of the day.

People, would you mind re-reading early pages of the topic, where it is explained multiple times why we can't even think about using the only algorithm that wouldn't be completely impractical, because we have neither the hardware nor the software required for that enormous task ?

Remember, in the current state of things (i.e. without major breakthroughs), the top researchers of the field don't expect the factorization of a 1024-bit RSA modulus by the next five years (it's closer to four nowadays, since the RSA-768 paper where they make that claim was released at the end of 2009). And we can never, for the life of the Universe, reasonably hope doing that by Trial Factoring. The cspire program (or any FPGA / GPU / whatever version of it, which might be several orders of magnitude faster but would still in no way make the task practical) might, with extreme luck, make a hit (again, see above for multiple posts containing figures) - but again, we shouldn't be spending too much processing time on that.

I think what Lionel is saying is that no matter what amount of computer power we could get, it's not going to happen, not for at least 4 or 5 years, and even at that point, it will still likely take upwards 6 months to factor.

By then, we'll be on the TI-Nspire CAS Silver-Titanium Explorer Edition.

Personally, I think that instead of the community focusing on factoring the RSAs, we put more of an effort towards programming on the existing exploits, and towards finding new exploits, we'll more than likely get more out of it as a community.

Yea, although in a lot of cases it's really hard to hide the exploit while publishing it. nleashed, for example, is pretty obvious, if you know what to look for. I was able to run my own code earlier through the same exploit that nleashed uses, just by looking at nleashed. Too bad the exploit destroys everything in RAM, so you can't call any OS functions or anything(or do anything like ndless, without basically rebuilding the OS in-ram)

++ I think we should first focus on getting asm on the nspire, THEN we can worry about RSA keys

And? Even if it happens (I'm not sure about that), in 4-5 years, many students will still have TI-Nspire ClickPads, TI-Nspire Touchpads and TI-83+/84+, unless a major change in exam organisation occurs.
It's not everybody who buy the latest brand new calculator...

I agree. The 83+ keys were factored about a decade after the calc was released. I have still seen people using TI-82s. By the time it is feasible to factor the keys, we'll still be using nspires.
