RIP: Len Sassaman, crypto expert and privacy advocate

We just received the very sad news that Len Sassaman has passed away at the age of 31 - Our heartfelt condolences go out to his family and wife Meredith (@maradydd on Twitter). From Wikipedia:

Len Sassaman (1980-2011) was an advocate for privacy, maintainer of the Mixmaster anonymous remailer code and remop of the randseed remailer.

Mr. Sassaman was a well-known cypherpunk, cryptographer and privacy advocate. He worked for Network Associates on the PGP encryption software, was a member of the Shmoo Group, a contributor to the OpenPGP IETF working group, the GNU Privacy Guard project, and frequently appeared at technology conferences like DEF CON. Sassaman was the co-founder of CodeCon along with Bram Cohen, co-founder of the HotPETS workshop (with Roger Dingledine of Tor and Thomas Heydt-Benjamin), co-author of the Zimmermann–Sassaman key-signing protocol, and was an organizer of the protests following the arrest of Russian programmer Dmitry Sklyarov.
