There are still a few good sources around.

Piracy.com: International Cryptography Freedom.

Cryptography links outside of North America

C4I.org strong crypto links

Treachery Unlimited

Shmoo

Speak Freely encrypted VOIP

utopia hacktic

uni-hamburg

PGP International

Sunet.se

It’s incredible how research in cryptography seems to have been wiped out.
