For lawyers, encrypting e-mail should be simple and routine. In Pretty Good Update for E-Mail Privacy, Washington Post writer Kevin Savetz reports on the December release of a new version of Pretty Good Privacy, once the standard for e-mail encryption until Network Associates bought it in 1997 and let it languish. You can download a noncommercial version of the new program for free from PGP Corp. A $39 personal edition, Savetz says, adds PGP Mail, which embeds PGP functions into Outlook, Outlook Express, Apple Mail and Microsoft Entourage.
