PGP Plugin for Eudora

First off, if you have a working setup (i.e. all the buttons work as expected, etc.) then I wouldn't suggest messing with it!

The best way to discover which version you have is probably to match the file sizes (although it isn't foolproof either).  Note that the same pgpplugin.dll file will work on either Eudora Light or Pro, if nothing else is specified.

Checking the version you have currently

In your Eudora plugins directory (usually c:\eudora\plugins), look for the file pgpplugin.dll.  Right click on it and select "properties".  This will give you the file size in bytes (don't go by the KB reading since some are close enough to report the same KB size).

PGP installs a different plugin depending upon what version of Eudora (3.x or 4.x) you have installed. To check which version you have installed, find the pgpplugin.dll file, right click on it, and select "Properties". Click on the version tab, then select "Internal Name" from the list. The Internal Name will show:

• pgpEudoraPluginV4 - You have the plugin for Eudora 4.x installed.
• pgpEudoraPlugin - You have the plugin for Eudora 3.x installed.

Naturally, if that doesn't match the version of Eudora you have installed, you should probably reinstall PGP.

Installing a new version

Shut Eudora down if it is running!  Find the old pgpplugin.dll in your Eudora plugins directory (again, usually c:\eudora\plugins) and rename it to something harmless (I like to use "pgpplugin.dll for version 5.whatever" as a filename).  Copy the new file into the same directory.

Note:  PGP 5.5.3a uses either the 5.5.3 Freeware (121,856) file or Light users can also use the first one on the table above (122,368) I'm told (this is the one included in the install).  Might as well be safe and use the one in the installed directory!  The difference in the files includes changing the message that shows up in the Version line in the signature.

If you have the files I'm missing, please feel free to email them to me, and I'll post them for others who may need them.  Thank you!

Outlook and PGP

• Outlook 97 is the version that is bundled with Microsoft Office 97 (I'll call it O97).
• Outlook Express is the version bundled with Internet Explorer (OE).
• Outlook 98 is the next version of Outlook 97.

• PGP 5.0 and up included a plugin for Outlook 97, but this plugin may cause problems for Outlook 98.
• PGP 6.0 will include a plugin that will work for both O97 and O98.

• PGP 5.5 has a plugin available for Outlook Express, which was included with PGP 5.5.5.
• For PGP version 6.5.0 (or 6.5.1?) and earlier: This "plugin" doesn't actually "plug in" in the normal manner. It actually renames the OE executable file, then copies another file there by the original name that loads PGP and allows PGP use within OE.
• PGP versions since 6.5.0 (6.5.1?): Relies on PGP Tray running. If you don't have PGP Tray running, you won't have the OE plugin.
• Note: If you upgrade Internet Explorer or Outlook Express, that plugin loader will be destroyed, and PGP will need to be reinstalled.
