On the subject of choosing keys randomly, rather than dividing up the keyspace... This seems like a very good idea to me. One potential problem is actually choosing the random keys. Have to be able to get entropy at a fast rate, and/or use a good PRNG. Both of these things would take time away from the actuall cracking (more time than just incrementing the key). And if a weak PRNG is used in order to save time, it's possible that it might favour certain keys and thus interfere with the attempt. Any ideas for a fast and good PRNG? ===================================================================== | Steve Reid - SysAdmin & Pres, EDM Web (http://www.edmweb.com/) | | Email: steve@edmweb.com Home Page: http://www.edmweb.com/steve/ | | PGP (2048/9F317269) Fingerprint: 11C89D1CD67287E68C09EC52443F8830 | | -- Disclaimer: JMHO, YMMV, TANSTAAFL, IANAL. -- | ===================================================================:)
