The international version supports at least 1024 bits.  That is the
reason why the US government has been giving Phil Zimmerman (author
of PGP) a hard time, though he recently won his court case.

I'm not sure about PGP, but DES actually gets _weaker_ if encrypted with
two keys.  Three keys does make it much stronger, though, as you say.
