Scouting report
Released Pretty Good Privacy as free software in 1991, and it escaped onto the internet worldwide. The US government opened a three-year criminal investigation into him for munitions export, dropped it in 1996 without charges, and the crypto-export regime never recovered. He later co-founded Silent Circle and worked on ZRTP for encrypted voice.
