Maybe there are just a bunch of "sleep's" in it  :)

I have been trying to get a free windows ssh client that could deal with
ssh2 supported keys.  The guy that writes putty claims that if he were to do dsa then
there would be some inherent problems that would make it easier to crack.
Something about his PRNG.

Don't know if we can assume better encryption or not.  If it does but
handling the keys make them more easily guessed it doesn't matter how good
the encryption is.
