README file for PGP International Freeware, Version 5.0 ------------------------------------------------------- OVERVIEW ======== Welcome to this international freeware release of PGP 5.0, commonly referred to as PGP 5.0i. This archive contains PGP 5.0i binaries for Windows 95 and Windows NT 4.0. The source code is available in another archive named pgp50i-win95nt-src.zip. The binaries contained in this archive are compiled from source code that was published in the following books by PGP, Inc.: 1) Pretty Good Privacy (tm) 5.0 Platform Independent Source Code June 14, 1997 ISBN 0-9649654-5-3 2) Pretty Good Privacy (tm) 5.0 Windows 95/NT Specific Source Code June 14, 1997 ISBN 0-9649654-6-1 3) Pretty Good Privacy (tm) 5.0 Platform Independent Source Code, 2nd edition July 9, 1997 ISBN 0-9649654-8-8 4) Pretty Good Privacy (tm) 5.0 Windows 95/NT Specific Source Code, 2nd edition July 9, 1997 ISBN 1-9649654-9-6 5) Pretty Good Privacy (tm) 5.0 Unix Specific Source Code, 2nd edition July 16, 1997 ISBN 1-891064-01-0 The books were exported from the USA in accordance with the US Export Regulations, and the pages were then scanned and OCRed to make the source available in electronic form. More than 70 people from all over Europe worked for over 1000 hours to make this release possible. We are pleased to be able to present a PGP version that is 100% legal to use outside the USA, because no source code was exported in electronic form. NB! This is copyrighted software. Please read LICENSE.txt before you start using PGP 5.0i. DIFFERENCES BETWEEN US AND INTERNATIONAL VERSION ================================================ The following changes have been made to the source code after it has been scanned in order to produce this version of PGP: 1. The version number has been suffixed with an 'i' (for 'international') 2. The default keyserver has been changed from pgpkeys.mit.edu to horowitz.surfnet.nl 3. The splash screen has been updated to reflect the new version DOCUMENTATION ============= The file pgp50manual.pdf contains the PGP User's Guide for Windows 95/NT. The manual is in PDF format, so you will probably need Adobe Acrobat Reader to view or print it. Adobe Acrobat can be downloaded from: http://www.adobe.com/prodindex/acrobat/readstep.html For more information on PGP 5.0i, including a list of known bugs, answers to FAQs, etc., please visit the International PGP Home Page, available online at: http://www.pgpi.com/ INSTALLATION ============ Installation is usually straight-forward. Just run Setup.exe and follow the instructions. IF YOU HAVE BEEN RUNNING PGP 5.0 AND YOU WANT TO SWITCH TO PGP 5.0i THEN COPY YOUR SECRING.SKR AND PUBRING.PKR BEFORE UN-INSTALLING PGP 5.0 BECAUSE THE UNINSTALL OF PGP 5.0 DELETES THESE KEYRINGS AND A PREVIOUSLY GENERATED KEY MIGHT GET LOST. NOTE: If you have previously installed PGP 5.0, Windows may be locking many of the DLLs you need to update. To unlock the DLLs: Exit any applications that may be using PGP (this includes PGPkeys, PGPtray, Eudora, Exchange and Windows Explorer). If you're running Windows 95: Ensure that you have an MSDOS window open. Select Start/Shutdown On the resulting dialog box, hold down control, alt and shift, and simultaneously left-click "No." This will shutdown the Windows desktop. On all Windows platforms: Enter the MSDOS window, and delete the following files: c:\windows\system\pgpwctx.dll c:\windows\system\pgp.dll On Windows 95: To get your desktop back, execute: explorer Windows may complain about missing files (especially PGPtray); do not accept any programs it finds as possible matches. This problem will be resolved after you finish installing PGP 5.0i. IMPORTANT, LAST-MINUTE RELEASE NOTES ==================================== 1) The Eudora plugin that is shipped with PGP 5.0 is not included in this release, because the .rc file necessary to build the plugin was missing from the source code books. The Eudora plugin will be included in a later release. 2) RSA key generation is not supported in this version. If you want to generate RSA keys, use PGP 2.6.3i instead or download the source code (pgp50i-win95nt-src.zip) and build PGP 5.0i for Personal Privacy. 3) Using Microsoft Word as your editor in Outlook is not currently supported. The Exchange/Outlook Plug-in will not be available in Word. Switching your editor back to the Outlook editor will correct the issue. TECHNICAL DETAILS ================= The pages were scanned using HP ScanJet 4+ and Agfa StudioScan IIsi flatbed scanners and OmniPage Pro 7.0 OCR software. The printed books contained line and page checksums to help validating the accuracy of the scanned code. After the pages were scanned, they were proof-read and any errors corrected until the checksums agreed. Because of this, you can be quite sure that no errors have been introduced into the files on their way from paper to electronic form, and that the files in this archive are (practically) identical to the original files, as published by PGP, Inc. The source code books also contained a list of MD5 and SHA hashes for all the files, to make it easier to validate each file. However, because the checksum algorithm used in the first edition of the source code books (from which most of the files have been scanned) does not take whitespace into consideration, we have not always been able to reproduce files that are 100% identical to the originals. They differ only in that they contain too many or too few spaces or TABs (which are irrelevant to the compiler anyway); apart from that they are identical to the originals. Sadly, the MD5 and SHA hashes are sensitive to whitespace, so only a few of the files in this archive produce the same hashes as the originals. :-( CREDITS ======= This project could not have been accomplished without the help of a large number of people, who devoted a greater or lesser amount of their valuable spare-time in order to make PGP 5.0 freely available to the world. Their help have been much appreciated, whether they have been operating the scanners, proof-read the source code, helped organizing or contributed in some other way.

Special thanks go to the Norwegian National Library for scanning part of the source code, UNINETT (the Norwegian Academic Network) for funding, and to the attendants at HIP '97 for being so patient and for providing last-minute proof-reading help. It's been a lot of work organizing this thing, but it's been a lot of fun, too. Whether you are an experienced PGP user or completely new to PGP, we hope that you will enjoy this new version, and that you will think it was worth all the effort we put into it. Happy encrypting, Teun Nijssen Stale Schumacher
