David Molnar began using PGP in 1993. He became interested (obsessed?) with figuring out "why it worked" and has been studying cryptography ever since. Now an undergraduate at Harvard University, he keeps up with security issues by attending courses, reading newsgroups, mailing lists, and conference papers, and attending DEF CON in his home city of Las Vegas. David is an ACM Student member and a member of the International Association for Cryptologic Research.
