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:


or directly at:


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:


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.

     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

     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.
