Newsweek, August 28, 1995, p. 10. Encryption: Pretty Good Phone Privacy [Photo] 'This is what I do': Cryptomaster Zimmermann In the wake of reports that the Clinton Administration is considering another Clipper-like scheme to ensure government access to encrypted conversations and e-mail, Phil Zimmermann is striking again. The 41-year-old author of the notorious PGP (Pretty Good Privacy) software program that scrambles e-mail so snoops can't read it is about to release a sequel: PGPfone, which allows people to use their computers as secure telephones. If you have a recent Macintosh (a Windows verson comes next month) and a fast modem, you and a friend can speak in total privacy. As with its predecessor, Zimmermann is giving the software away, via MIT's Internet sites. Meanwhile, he's still waiting to hear whether the Feds will indict him for export violations in the distribution of PGP. Does Zimmermann worry that releasing PGPfone -- which can theoretically frustrate law- enforcement wiretaps -- will further inflame those who wish him arrested? "I'm a cryptographer, " he says. "This is what I do." [End]
