rsatool exits without ending the process

hi folks,

got an issue while using rsatool2 v 1.7 for testing a 2048bit key. it starts well and when it goes about 30 minutes exits without any error and no result is getting back. can u advice some solutions ?

if you don't have one of those setups, the best advice would be "forget about factoring 2048-bit RSA on a regular PC"

well i can say i have access to some data centers. what`s the deal if we get a parallel processing script ready! I can handle as many as friends want. I mean we can develop a solution for it if you help.

can you guide me to replace the key inside a linux machine !

I worked with IDA + GDB + linux 64 vm. but i have problems suspending and getting data back to IDA after machine starts.

data centers won't be cost effective at all. as you can see here there's a 200k bounty on 2048-rsa which is not claimed yet. the story has changed after quantum computing though - above links are articles about quantum physics.

coming to your "replacing the key" question: it depends.

  1. what do you want to do exactly?
  2. working on linux kernel (system) level or an application?
  3. what's your goal after replacing the key?

1- replace the key at init of kernel where startup scripts are running so encryption key of files to be encrypted are getting changed as planned.

2- kernel level from the boot moment to the point where encryption key getting picked.

3- be able to read license template and replace items as needed.
