Its theoretically not impossible is what I meant. Unless there is a breakthrough in factoring -stares at Xeda- this is effectively impossible. Who knows maybe we will find another way to find the answrs we want.

Pretty darn sure all it takes is decompressing it to get a raw file. the .img isn't enough, I believe, since RunOS doesn't do extraction.

Yes, less free space, though the OS in ZIPped form is only 3-4 MB (7-9 MB for phoenix.raw, obtained from decompressing the ZIP resulting from the Blowfish decryption of the 8070 field)

Several seconds, AFAICS.

We do already have the public keys - but they're too hard to factor in order to deduce the private keys.

Do you think Zeda could look at the hex and get the key using his special hex powers and maths spells?

If it helps, I have been attacking primes and some prime theory. I haven't gotten anywhere that nobody else has, but I am giving it a whirl

EDIT: It might help if I actually understand the concept of these public and private keys... I've only been guessing in that area and I still don't understand how the method works to prevent access to stuff.

Don't bother -- It's impossible. (No, seriously. Not impossible like going back in time, but rather less probable then pretty much anything you can think of.)

Hi, I'm trying to remove boot2 from my nspire.  Not being very experienced with programming, I'm having much trouble compiling TNOC.  Frustrated   Could someone please help me?

TNOC dosen't need to be compiled... It comes with a binary. Assuming the previous sentence does not apply because you're using linux, where does it fail?

Still its a chance if not very large that they might figure something out. I have also been wondering about this. Could someone give a comprehensive tutorial/information about how this works. Chances are almost 100% we'll find nothing but it still would be a nice interesting experience.

Look, I'm sorry to rain on the parade here, but I'm just being honest. Our time is better spent on things that can be accomplished. We can't factor the RSA key in the forseable future, unless we get quantum computers.
