Qualcomm products mentioned within this press release are offered by Qualcomm Technologies, Inc. and/or its subsidiaries.

Qualcomm Incorporated (NASDAQ: QCOM), a world leader in wireless communications and advanced electronic messaging solutions for the Internet, and Pretty Good Privacy, Inc., the world leader in digital privacy and security software, today announced that Internet users will now be able to easily protect the privacy and security of email communications using the world's strongest encryption software for individual and business users.

With a single click of a mouse button even novice computer users will be able to easily encrypt, decrypt and/or digitally sign messages from within Eudora® software's easy-to-use graphical user interface. This completely secure Internet email package represents the combination of best of breed solutions from the #1 developer of Internet email programs and the #1 developer of encryption solutions.

PGP for Personal Privacy, Version 5.0 (DSS/Diffie-Hellman) will be integrated into Eudora Pro™ and Eudora Light™ software. Versions will be available on the Windows® 95, Windows NT 4.0 and Macintosh® platforms for purchase from Qualcomm's website in July. Boxed versions will be available in retail channels shortly thereafter. "Pretty Good Privacy's best-of-class solutions, strong encryption technology and innovative software echo Qualcomm's philosophy and make them the perfect match for providing secure email for Eudora software customers," said Jeff Jacobs, vice president and general manager of Qualcomm's Eudora division.

"Joining forces with Qualcomm enables both companies to provide a tightly integrated complete solution for Internet email security that address the needs of the world's largest installed base of Internet email users," said Phil Dunkelberger, president of Pretty Good Privacy, Inc.

Employing Diffie-Hellman public key cryptography, PGP's strong encryption software protects personal email messages, attachments and files with absolute security. A user creates two separate keys: a public and a private key. The public key encrypts information and is widely distributed to all email recipients with whom the user communicates. The private key is held only by the creator of the key pair. To encrypt a message for a recipient, the sender uses the recipient's public key. When a person uses his correspondent's public key, only the intended recipient can decrypt and read the message. Because only strong cryptographic keys are used, senders can be absolutely certain that the only people who can read the message are the intended recipients.

A message can also be digital signed. For digital signing, the sender uses his private key to digitally sign the message. The recipient verifies the signature (authentication) and contents (integrity) by using the sender's matching public key. Using Eudora's EMSAPI plug-in architecture, the encrypt, decrypt, verify and sign functions are part of Eudora software's toolbar for easy, convenient use.

PGP for Personal Privacy, Version 5.0 (DSS/Diffie-Hellman) employs the DSS/Diffie-Hellman (the El Gamal variation of Diffie-Hellman) algorithm in the version of PGP that comes with Eudora software. Keys based on RSA public cryptography will be available as a separate option via a simple $5 software upgrade from the Pretty Good Privacy, Inc. website at Pretty Good Privacy, Inc. publishes its encryption source code which ensures extensive peer review and public scrutiny. In addition, the PGP for Personal Privacy, Version 5.0 (DSS/Diffie-Hellman) plug-in to Eudora software implements PGP/MIME, by which attachments including images, voice and multimedia in email are secured. Unlike someother proposals for secure email, PGP/MIME is on track to become a standard of the IETF.

The public key cryptography algorithms employed in PGP are extremely secure. According to William Crowell, Deputy Director of the National Security Agency, testifying before the U.S. Congress on March 20, 1997. "If all the personal computers in the world—~260 million computers—were put to work on a single PGP-encrypted message, it would still take an estimated 12 million times the age of the universe, on average, to break a single message." Companies and individuals recognize the strength of PGP software. In fact, over 3 million people (including over half of the companies in the Fortune 100) currently use PGP.

With over 18 million users, the Eudora family of software products is the world's most widely-used Internet email solution, providing comprehensive client/server solutions for Internet/intranet messaging. Available for the Windows®, Macintosh® and Newton® platforms, Eudora Light™ and Eudora Pro™ are best-of-class Internet email client software products. Eudora Pro 3.x has powerful features that deliver exceptional levels of productivity, ease-of-use and flexibility for users who process high volumes of Internet email, while Eudora Light 3.0.1 software sets new standards for Internet email freeware with a wide range of enhanced capabilities. Eudora WorldMail™ Server is powerful server software that provides fast, reliable messaging services for the Windows NT platform.

OEM and bundling agreements include industry leaders such as Microsoft, IBM, NETCOM and 3Com. Eudora Pro software has been licensed to a wide range of corporations including MCI, Cisco, GTE, Lockheed Martin and Schlumberger. Many of the world's leading universities, including MIT, Stanford, The University of California, Brown and Cornell, also use Eudora Internet email software.

Pretty Good Privacy (, founded in March 1996, is the leading provider of digital-privacy products for private communications and the secure storage of data for businesses and individuals. Pretty Good Privacy's original encryption software for email applications (PGP) was distributed as freeware in 1991 by Phil Zimmermann, chief technical officer and one of the founders of Pretty Good Privacy, and allowed individuals, for the first time, to send information without risk of interception. With millions of users, it has since become the world leader in email encryption and the de facto standard for Internet mail encryption. Over one half of the Fortune 100 companies use PGP. In order to provide only the strongest encryption software, Pretty Good Privacy publishes all of its encryption source code and algorithms for extensive peer review and public scrutiny.
