    To: The PGP Community
    From: Jeffrey I. Schiller <jis@mit.edu>
    Subject: PGP 5.0 Freeware is available from MIT

    I am pleased to announce the availability of PGP 5.0 Freeware from the
    MIT Web Site. PGP 5.0 Freeware is available for non-commercial use under
    license from MIT, PGP Inc. It uses the RSAREF toolkit licensed from RSA
    Data Security.

    This new version is a long awaited major upgrade and improvement to PGP
    2.6.2. It has a native Windows '95, Windows NT and Macintosh interface.
    It supports additional ciphers, as well as new key types and message
    formats. Internally it is much improved as well.

    This release marks a major transition to a new public key infrastructure
    based on the Diffie-Hellman (DH) public key algorithm for privacy and
    the Digital Signature Standard (DSS) for digital signatures. The RSA
    algorithm is still supported and this version will work with the old RSA
    keys you may already have. However all new keys generated by this
    version will be DH/DSS keys. Many of the internal performance
    improvements are only available when used exclusively with DH/DSS keys
    (this is because using RSA keys requires PGP 5.0 to be backward
    compatible with PGP 2.6.2 which requires PGP 5.0 to use less efficient
    message formats).

    This version also includes automated keyserver support. It can
    automatically fetch PGP keys from the MIT keyserver (and other
    keyservers) as well as offer to upload any newly created keys.

    It also comes with plug-ins for Eudora and other major mail utilities.

    At the moment it is only available for Windows '95, NT and MacOS. A Unix
    (Linux) version is in the works but isn't ready yet, but we hope to have
    it ready within a week or two.

    Source code for this version was distributed at last weekend's
    cypherpunks meeting in hard copy form. Source will eventually be made
    available electronically, but isn't ready yet.

    You can find the Freeware PGP at either the PGP Home Page at:

      http://web.mit.edu/network/pgp.html

    or directly at:

      http://web.mit.edu/network/pgp-form.html

    Note: We anticipate a significant amount of traffic while people
    throughout the U.S. and Canada download PGP. Please be patient with the
    server (and with us)!

    You may be interested to know that the trial version of the new PGP 5.0 product for the
    Intel PC is available in Europe.  This should not have been exported from the US but it
    took less than a couple of hours to turn up over here after its US release.  This product
    is truly a major step forward (on the PC at least!) and gives good email security and a
    user friendly interface to MS Exchange, MS Outlook and Eudora. There appear to be
    versions for the Mac as well although I cannot verify this.

    You can get this trial version at:

    	ftp://ftp.hacktic.nl/pub/replay/pub/incoming/pgp50trial.exe

    This version expires in a couple of months and I have asked Phil whether he intends
    to make the product available here in Europe. I will let you know if I get a response.

    One more nail in the coffin of crypto export controls!

         Pretty Good Privacy Releases First in Next Generation of
         Easy-To-Use Encryption Products

         June 17, 1997

         San Mateo, Calif., June 16 -- Pretty Good Privacy, Inc.,
         the world leader in digital privacy and security software,
         http://www.pgp.com, today released PGP for Personal Privacy,
         Version 5.0, the first member of the company's next
         generation of multi-platform, easy-to-use encryption
         products for individuals and small businesses.

         PGP for Personal Privacy, Version 5.0, available
         today for sale via download from the Pretty Good Privacy
         website, gives people complete confidence that their email
         messages and files can be safeguarded by the strongest
         commercial cryptography available.

         PGP for Personal Privacy, Version 5.0 is an inexpensive
         software program, built on a new code base, which makes
         encrypting and digitally signing email and files as easy as a
         single click of a mouse. Now, for the first time, users can
         quickly and easily protect legal documents, medical records,
         insurance files, intellectual property... whether they use the
         Windows 95, Windows NT 4.0 or Macintosh platforms. It is
         the genesis of a new line of encryption products that feature a
         dramatically enhanced graphical user interface, making
         encryption more accessible than ever before for novice
         through expert computer users.

         In addition to the unique graphical user interface, there are a
         host of new features (including multiple message
         cryptography, selective text cryptography and algorithm
         choice) which turn the once difficult operation of protecting
         email and documents into a very simple act. The principal
         functions of PGP for Personal Privacy, Version 5.0 can be
         operated from within the toolbar of five of the world's most
         popular email programs: Eudora Pro, Eudora Light, Microsoft
         Exchange, Microsoft Outlook and Claris Emailer. The millions
         of users of these email programs can rapidly encrypt and
         digitally sign their email and documents. Finally, PGP for
         Personal Privacy, Version 5.0 integrates innovative new
         mechanisms to find and store public keys almost
         instantaneously on a network of public key servers containing
         tens of thousands of public keys worldwide.

         "Privacy in the information age has been hampered by
         difficult-to-use software that was built for people who were
         technologically very savvy," said Phillip Dunkelberger,
         President of Pretty Good Privacy, Inc. "With PGP for
         Personal Privacy, Version 5.0, encrypting files and messages
         or finding someone's public key is now as easy as pushing a
         single button."

         PGP for Personal Privacy uses the same strong encryption
         technology that made PGP the worldwide de facto standard
         for sending secure messages across private intranets, public
         extranets and the global Internet. A message encrypted with
         128-bit PGP software is
         309,485,009,821,341,068,724,781,056 times more difficult to
         break than a message encrypted using standard 40-bit
         technology. Following in the tradition started by Phil
         Zimmermann, creator of PGP and Chief Technology Officer,
         the code has been made available for peer review, ensuring
         that PGP has no backdoors and is fundamentally secure.

         "Encryption is a critical tool for the Net because it provides
         people with privacy, which has been lacking," said Charles
         W. Brandon, one of the early Beta testers, Chairman of The
         Reality Foundation, and one of the co-founders and former
         Senior Vice President of Information Systems for Federal
         Express Corp. "PGP for Personal Privacy, Version 5.0 is a
         graphically rich tool that makes encryption accessible for
         everyone and solves the privacy issue for individuals today."

         PGP for Personal Privacy, Version 5.0 is ideal for individuals
         and small businesses. For example, if John wishes to send
         financial data to his accountant, he can now confidently
         encrypt, digitally sign and send his tax information via email
         without concern that the data may be intercepted while in
         transit. In a business setting, if Susan, the Purchasing
         Manager, is working on a bid with Tom, a co-worker in
         another location, she can encrypt the file with Tom's public
         key and then place it on a common server on the network
         with the knowledge that only Tom can read it. PGP for
         Personal Privacy, Version 5.0 makes the once daunting task
         of encrypting email and files easy to do and manage.

         On June 16, 1997, Pretty Good Privacy, Inc. will make trying
         PGP even easier by offering a free 30-day trialware version
         of PGP for Personal Privacy, Version 5.0 at
         http://www.pgp.com.

         Public Keys Provide Privacy: In Brief

         In public key cryptography, a person creates a key pair: a
         public key which he/she distributes and a private key which
         he/she keeps confidential. Each one complements the other,
         but is useless without the other. For example, if Alice wishes
         to send a secure message to Bob, she encrypts her message
         with Bob's public key. Bob retrieves the message and
         decrypts Alice's message to him with his private key. (Bob
         alone should be the keeper of his private key). Using his
         private key, only Bob can decipher those messages which
         were encrypted using his public key.

         Upgrades for Existing Customers.

         Existing customers interested in upgrading to PGP for
         Personal Privacy, Version 5.0 should visit the Pretty Good
         Privacy website at http://www.pgp.com for details.

         New Features in PGP for Personal Privacy, Version 5.0

         * Key Server Integration: A user can easily and automatically
         post a public key to a public key server with a single mouse
         click. By storing one's public key on a server, it is easily
         obtained by others who wish to communicate with the
         creator. Likewise, one is easily able to search the key server
         for other's public keys.

         * Multiple Message Cryptography: PGP speeds up
         information access and dissemination by allowing a user to
         type in his/her passphrase just once during a timed session,
         enabling the user to decrypt or sign several messages without
         having to continually type in the passphrase.

         * Selective Text Cryptography: On a PC running Eudora, one
         can selectively choose text then use the PGP pop up menu to
         perform any PGP operation. On a Macintosh, the new
         PGPmenu establishes text encryption and digital signatures
         via the PGP icon in the menu bar. Via PGPmenu or PGPtools,
         the application's main function bar, the user can engage the
         functions of PGP for Personal Privacy.

         * Algorithm choice: As mentioned earlier, PGP for Personal
         Privacy is now offering a choice of algorithms:
         DSS/Diffie-Hellman (the ElGamal variation of Diffie-Hellman)
         and RSA.
