Len frequently appeared at DEF CON; was a co-founder of CodeCon with BitTorrent's Bram Cohen and co-creator of the Zimmermann–Sassaman key-signing protocol; worked at Network Associates on PGP and contributed to OpenPGP and GNU Privacy Guard; was a senior systems engineer and security architect for Anonymizer; a member of the Shmoo Group and organized protests in response to the arrest of Dmitry Sklyarov.
Len counted amongst his friends and associates Bram Cohen, Werner Koch, Dan Kaminsky and Phil Zimmermann. He is survived by his wife, noted programmer, sci-fi author and Boing-Boing contributor, technologist and bio-hacker Meredith L. Patterson.
