PGPnet secures all TCP/IP communications between the local machine and any other machine running PGPnet. PGPnet has been successfully tested with Cisco routers (requires Cisco IOS 12.0(4) or later with IPSec TripleDES). Self-Decrypting Archives You may now encrypt files or folders into Self-Decrypting Archives (SDAs) that can be used by users who do not even have PGP. The archives are completely independent of any application, compressed and protected by PGP's strong cryptography. Integrated PGP Command Line This version incorporates the popular command line version of PGP for Windows platforms. This product provides a convenient way to integrate PGP with other Windows applications and automated processes on your desktop system. Please note that this is intended for single user/workstation use. For use on servers, customers are required to purchase the PGP e-Business Server product. Please contact your local Network Associates Sales representative for more information. Automated Freespace Wiping PGP's Freespace Wipe feature now allows you to use the Windows Task Scheduler to schedule periodic secure wiping of the free space on your disk. Hotkeys The Use Current Window feature has been significantly enhanced by the addition of Hotkeys. By using a configured key combination, the Encrypt/Decrypt/Sign functions can be automatically invoked without using PGPtray. This feature is very useful for users using messaging applications for which PGP does not currently have a plug-in, such as Netscape Messenger. Fingerprint Word List When verifying a PGP public key fingerprint, you can now choose to view the fingerprint as a word list instead of hexadecimal characters. The word list in the fingerprint text box is made up of special authentication words that PGP uses and are carefully selected to be phonetically distinct and easy to understand without phonetic ambiguity. Support for Outlook 2000 and Outlook Express 5.0 This version of PGP adds support for sending and receiving encrypted email in Microsoft Outlook 2000 and Outlook Express 5.0. HTTP Proxy Support If you are behind a firewall with an HTTP proxy server, PGP now supports accessing HTTP keyservers through the proxy. To use this feature, you must configure the proxy server address in your Internet Explorer preferences. Smart Word Wrapping The word wrapping in PGP now automatically rewraps paragraphs and even quoted paragraphs resulting in much cleaner signed messages. PGP version 6.5.2a enhancements Support for Windows 2000 operating systems. This release of PGP introduces support for Microsoft's latest releases of Windows. All PGP functionality is available in Windows 2000 except PGPnet. PGPnet will support Windows 2000 in future releases of PGP. Windows 2000 IPSec interoperability. PGPnet running on non-Windows 2000 systems can establish VPN connections with the built-in Windows 2000 IPSec client. (The Windows 2000 system must be running the Windows 2000 High Encryption Pack.) Intel Pentium III Random Number Generator (RNG) support. If your computer is equipped with the Intel RNG, PGP will use the random data generated by the chip in addition to our own entropy collection whenever random data is needed for key generation and encryption. The Intel RNG is currently only available with select Pentium III chipsets, including the Intel 810 chipset. Automatic email plug-in pre-selection. PGP will now automatically pre-select email plug-ins to install on your system based on what messaging applications are installed. Nevertheless, you are still able to change the selected plug-ins at install time.

SYSTEM REQUIREMENTS To install PGP on a Windows 95, 98, 2000, or NT system, you must have: Windows 95, 98, 2000, or NT 4.0 with Service Pack 3/4/5 32 MB RAM 16 MB hard disk space for the client install If you plan to run PGPnet on the system, you must also have: Microsoft TCP/IP A compatible LAN/WAN network adapter Note: PGPnet functionality is not available for users of Windows 95a (the original release of Windows 95) or Windows 2000. PGPnet supports Windows 95b (OSR2), Windows 98 and Windows NT 4.0. KNOWN ISSUES PGP issues Mismatching your keyring files can result in data loss. Your public keyring file and private keyring file must be kept in sync. If, for instance, you select a public keyring file that does not contain the public portion of your private key without also changing the private keyring to the corresponding file, you and others will not be able to encrypt to exported versions of your key after that time. In most cases, simply updating your key from a public copy on a keyserver will fix this. However, it is recommended that the keyring files always be kept in sync. A future version is expected to correct this issue. Some PGP Versions 6.0 and later features are incompatible with previous versions of PGP, so we feature a "compatible" export format that strips incompatible features such as Photo IDs. Selecting "Include 6.X Extensions" in the Export dialog enables these features to be exported. By default, PGP exports in compatible mode. You may change the default in the Advanced Preferences dialog. When sending a key to a PGP Certificate Server Version 2.0 or above, Photo IDs always accompany the key. The default LDAP server in PGP 6.x supports this. On Windows 95/98, the Free Space Wiper will reset every time another program writes to your disk while the wiping process is in progress. This is similar to defragmentation programs, and is required by the Operating System. For optimal wiping, make sure to close all open applications. On some systems with very low amounts of RAM, it may be advisable to also shutdown Windows Explorer. The Windows Explorer provides PGP with information only about the target of a shortcut and not the shortcut itself. If you use the Wipe feature in the Explorer, the shortcut itself will not be wiped. The actual target will be wiped. When using PGPtools, the shortcut will also be wiped. Hotkeys are for use with applications that support general text editing. Using Hotkeys with some applications may result in unpredictable behavior. The PGP Exchange/Outlook plug-in does not support Microsoft Word as an e-mail editor. We strongly recommend that VirusScan users upgrade to VirusScan Version 4.0.3 or later to take advantage of the newest virus DAT file update features. PGPnet issues Do not attempt to manually uninstall PGPnet. It is very important that you use the PGP Uninstaller to remove PGPnet. PGPnet makes extensive modifications to the registry and changes the bindings on network adapters. The PGP Uninstaller can be accessed via the Add/Remove Programs control panel. (Windows NT only) As a precautionary measure, in the unusual event that there is an incompatibility between your network card driver and PGPnet, you can create a "No Networking" hardware profile prior to installing PGPnet on your system. The "No Networking" hardware profile can be used later if an incompatibility occurs. To create a "No Networking" hardware profile, right click on "My Computer," select Properties, and then select the Hardware Profiles tab. Use the Copy button to create a copy of the Original Configuration. Get Properties on your copied configuration and click the Network tab. Finally, select the "Network-disabled hardware profile" checkbox. Click OK to both windows and then you are done. (Due to a Windows bug we recommend that you restart once and double-check that the "No Networking" configuration is working before you install PGPnet.) (Windows 95 only) You may experience a loss of networking after resuming from standby mode. You must reboot your machine to resume network activity. PGPnet is not compatible with the Intel EtherExpress 16 driver. Installing virtual private network software such as PGPnet on the same machine as a firewall or another VPN client is highly likely to cause problems. We recommend uninstalling the other product prior to installing or choosing not to install PGPnet on such a machine. You cannot use the default MSN dialer to connect to MSN if PGPnet is installed. To connect to MSN with PGPnet, use the Microsoft Dial-Up Networking client.
