I haven't seen the USG RSA key -- if it's 512 bits, that would be a humorous next factoring target.
Talking of factoring I wonder if anyone on the list has seen the article in this months new scientist regarding a new link found between energy levels in hydrogen atoms and generation of large primes, I don`t remember the details (I only scanned the article as even the elementary explanation of the physics involved was beyond me), The thrust of the article was that work was in progress on a variant of this that could factor large numbers significantly faster than current methods. Anyone with more background in this sort of thing care to comment?
