Liberty requires security without intrusion, security plus privacy. Widespread police surveillance is the very definition of a police state. And that’s why we should champion privacy even when we have nothing to hide.

Skein is a new family of cryptographic hash functions. Its design combines speed, security, simplicity, and a great deal of flexibility in a modular package that is easy to analyze.

Skein is fast.

Hopefully it is also cryptographically secure.
