An obituary posted on Facebook by Sassaman's friend and fellow hacker Pablos Holman recounted the pair's early work on crypto-systems after they met in 1999.Young cryptographer ends own life (Thanks, GuidoDavid.)
"We were reimagining our world, riddled with cryptosystems that would mathematically enforce the freedoms that we treasured. Anonymous remailers to preserve speech without fear of retribution; onion routers to ensure nobody could censor the internet; digital cash to enable a radically free economy."
While much of their work was an academic "geek utopia exercise", Sassaman liked to "get his hands dirty", which led to numerous visits from Federal agencies over remailer abuse, according to Holman: "Len, you are, in fact, an inspiration to those of us who inspired you. You made something great of your life. You left a lot behind for us. Thanks for letting me be a part of it all."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
