A very interesting website.  I followed the links, and found this document:

http://www.nsa.gov/ia/programs/suiteb_cryptography/index.shtml

It seems that the NSA is moving away from RSA/DH etc. cryptography,
and now "only" approves their use for secret level material.  They are
instead pushing elliptic curve cryptography.  I hadn't realised that
there was such pressure to move away from traditional key exchange.
Is this about the fear of quantum computing, or something else?

EC in gpg is still some way off, it seems.
