768-bit RSA factored

[David Shaw]

No terrible shock - we knew this was coming, but still, how  
wonderfully neat, and a new factoring record, too.

Note that 1024-bit RSA has not yet been factored, but if you haven't  
phased it out yet, it's really time to get started.  It's supposed to  
be completely phased out by this year anyway, at least by those  
following NIST and a few other guidelines.
