1. Introduction

PgpEudra is a PGP-shell that runs as an extension to Eudora. PGP (Pretty Good Privacy, written by Philip Zimmermann) is a DOS-program for very good public key encryption of textfiles. Eudora Light from QUALCOMM is a very popular mailprogram for MS-Windows. PgpEudra is just an interface between these programs. It does not replace either of them.

Without a PGP-shell it's hard to reply to coded mail. Save the received mail in a file, go to DOS, PGP-decode it, return to Windows if you prefer a Windows editor, type an answer, go back to DOS, PGP-code the file, return to Windows and send the file. With PgpEudra you can run PGP from Eudora's menu or by pushing a button on Eudora's toolbar.

PgpEudra finds out what to do. First it copies the data in the current window to a textfile on disk. Then it starts PGP.EXE in a DOS-box and specifies the right command-line to decode or encrypt the text. The decoded text is returned in the current window if possible. Otherwise you can paste it into an editor of your choice. The encrypted text is always put in the current window.

You don't have to read the entire manual. I'm sorry for writing so much. Read at least sections 2, 3, 4 and the start of section 5. Then run the program, see if and how it works. If you want something you can't figure out, read the appropriate section and try again.

2. System requirements

The unzipped package uses around 200 kB disk space (both programs and manual). The program is less than 100 kB and uses almost no extra memory. You don't need any VBX-control libraries or additional DLL.

Do not expect, that it always works with beta versions of Eudora. Sometimes QUALCOMM changes something and there are so many betaversions, that I don't like to spend time on them. Besides, I need some time too, to get them and check what they do.


You need a 80286 computer (or better) and MS-Windows 3.1 or Windows95. It will probably run under MS-Windows 3.0. I used one 3.1 function, but this is an undocumented 3.0 function.
Maybe this version does not run on OS/2 Windows. It seems that PgpEudra does not get a notification message that PGP has terminated. I try to find out what exactly fails but I don't have OS/2 so it's a bit complicated.
Of course you'll need an Eudora version. Eudora Light 1.5.x will do, but it is reported to run with Eudora Pro as well. I do not support Eudora 1.4 anymore, although it will partly work. You'd better get Eudora 1.5.2 or newer, because it has new features that PgpEudra uses. It does not run with 32-bit versions of Eudora.


You need a 80386 computer (or better) and Windows95 or NT and Eudora(32) (Light or Pro). It does not work on Windows 3.1 (not even with win32s) nor with Eudora(16).

3. Installation

Unzip the ZIP-file with PKZIP version 2.04g (or later). In this ZIP-file you'll find another ZIP-file and a signature (SIG) file. Unzip this ZIP-file and copy the program PgpEudra(16) (= PEICS16.EXE) or PgpEudra(32) (= PEICS32.EXE and PEICS.DLL) to Eudora's directory.

If you want to use the program on a network you can try PgpEudra on your local PC. Eudora will probably be in the DOS PATH, so PgpEudra can find it. If (in Properties) you specify the directory where Eudora is, as the working directory for PgpEudra, it can find Eudora too.

Adding PgpEudra icon
Open Eudora's programgroup. Choose "File | New..." in Windows programmanager, select "OK", choose "Browse" and select the Eudoradirectory. Select the program file (PEICS16.EXE or PEICS32.EXE).
PGP Configuration
If you've installed PGP correctly, it should work now. Check that you have the environment variable PGPPATH set to the PGP-directory. PgpEudra searches in this directory for PGP.PIF. If it does not find that file it looks for PGP.EXE. If it does not find that one it searches the DOS PATH. If that fails it returns an error and stops.
In Windows 95
Windows 95 does not have a PIF-Editor anymore although PIF-files are still supported. But you can set the options for the file PGP.EXE instead. In "My computer" click on the pgp icon, choose "File|Properties" from the menu, choose "Program" and uncheck "Close on exit".
In Windows 3.x
On a 80386 PC (or better) you can edit/create PGP.PIF to run in a DOS-Window instead of fullscreen textmode. Besides you can choose to keep the DOS-box open after PGP has terminated. Then you can see the results of PGP. There's a PGP.PIF file included in this distribution. I do not promise that it works, but it might be a good starting point for creating your own.
Temporary files
The program creates temporary files to pass information to PGP and back. The TEMP or TMP environmentvariable tells PgpEudra, where those files should go. If these variables are not set, it will make them in "C:\". If you set PGPtempdir in PEICS.INI, this will override the settings by TEMP or TMP. You might want to set this to a ramdrive, because this will guarantee that there are no stale (chunks of) files left on the disk when the system or the program hangs.
If the files exist on start-up, you'll be prompted if they can be overwritten. If you choose "Cancel" the program terminates without overwriting them.
More users
If you use Eudora with more users (and more pop-accounts), you may have specified a command-line for Eudora in Program Managers "File | Properties". Then each user can have his own start-up icon and his own maildirectory. You'd like to create the same for PgpEudra. It will pass the command-line to Eudora. Besides each user can have his own PEICS.INI. (See 6. PEICS.INI)

4. How to start

You can click the PgpEudra icon. It will launch Eudora. If it cannot find EUDORA.EXE (Eudora Light/Pro) in the directory where PgpEudra is, it will search the DOS PATH. PgpEudra(16) 0.3x tries to run WEUDORA.EXE (PC Eudora 1.4.x) if it cannot find EUDORA.EXE. If it cannot any Eudora program on disk or in memory it shows a messagebox
"Eudora not found: tried these files:"
followed by the files it searched.

If Eudora is already running, you can start PgpEudra later. It will add its menu's to Eudora. PgpEudra always scans all toplevelwindows before starting Eudora. If you got an error message "Eudora not found", you probably have a different Eudora version. If PgpEudra is already running (with Eudora), clicking the icon again will move you to Eudora's window.

5. Using the program

This program is not a complete PGP-shell. If you need special features use another PGP-shell or go to the DOS-commandline. This program is intended for the common tasks. It can encrypt and decode mail, sign and check a signed message and add a public key to the public keyring. The program finds out what to do. It has only one menu-item "Run PGP...".

Every time you use PGP you'll have to follow these instructions:

  1. Open the window where your text is.
  2. Select "Message | Run PGP..." or click on the button on the right side of the toolbar (in Eudora 1.5.x and 2.x, 3.x).
    The program shows a dialogbox with what it expects it should do. It shows part of the text to check if this is correct. If it is the text from another window, you'll see it here. Choose [OK] if you agree to run PGP.
  3. When PGP has finished, close the DOS-window or type EXIT in DOS. You should read PGP's results from the DOS-window, so you'd better keep it open.

4. After closing the DOS-box you see the changed text or a dialogbox that tells what happened. If PGP returned an errorcode it will be shown here, but not in plain text. Usually this does not happen. If it does PGP has already written an error message on screen.

Some definitions:
An "output window" is a window that has a "To:" field and is created with a "New", "Reply", or "Forward" menu-selection. In this window you can edit text.
An "input window" is a window with only text. It is created for incoming messages and can not be edited.

The next sections assume that you are at section 2 of the description above.

5a. Decoding

If PgpEudra found a PGP MESSAGE BEGIN/END block, it will show a "Decode" dialogbox. This will decode the text from the BEGIN/END block.

PgpEudra copies the text to the window where it came from. If this is an an input window you can only read the text. Everything else you try to do (forward, reply, save), will be done on the original encrypted text. Besides reading and scrolling you can copy a selection to the clipboard (Edit|Select All & Edit|Copy).

If you've sent an encrypted message from an outputwindow you can later decode it, provided that you've also encrypted for yourself. But Eudora marks this output window as read-only, so you can only read the (decoded) text, as in the input window.

If you've set the INI-setting CopyToReadOnly=0, then PgpEudra shows a dialogbox that lets you choose where you want your decoded text to go. It can copy the text to the clipboard (the default, [Yes]) or ([No]) to the textwindow, where it came from. If you chose to copy the text to the clipboard, you can paste your decoded text from the clipboard into an editor of your choice.

After decoding PgpEudra scans the decoded text for a key. If it found one you'll be prompted if you like to add it to your public keyring. See 5c. Adding a new key.

There's an easier way to decode if you want to reply to an encrypted message. See 5d. Reply to coded mail.

5b. Encrypting

If PgpEudra finds no coded or signed text in an output window , it shows an Encrypt-dialogbox with the previously typed text and the recipient name from the "To:"-field. You can change this name, if the keyname is different. It's very convenient to have the e-mail address in the public key. PGP uses this name to find the key of the recipient. PgpEudra extracts the e-mail address from the text in the "To:" field, if it finds an '@' sign.

Here you can add options, if you need. Put them in the editbox before the recipients name (e.g.: -s hans will sign the message encrypted for "hans".). If you set "AlwaysSign" in PEICS.INI every message that must be encrypted will be signed too. The default PGP-options are "-aetw".

The program reads the "Cc:" (Carbon copy) field from the message window and adds those names to the "Encrypt for" field in the "Run PGP..." dialogbox. The name in the "Encrypt for" line in PEICS.INI will be added too. This makes it easy to encrypt every message for your self (so that you can at least read all mail encrypted by you ;-).

If you delete the recipients' name or if there was none in the "To:"-field, you'll see the "ClearSign" header. (See 5e. Clearsign a message). If you keep the [Shift] key down while starting the dialogbox, then the nicknames in the "To:"- and "CC:"-fields will be expanded.

5c. Adding a new key

If there's a "PGP PUBLIC KEY BEGIN/END" block in the text, you can add it to the public keyring. PgpEudra will pass the complete message to PGP. After running PGP there's nothing to do for PgpEudra. PGP has showed already what it did.

5d. Reply to coded mail

This is very common use, so I made it as easy as can be. Part of this is like 5a. Decoding.

1. Select "Message | Reply" (or push the Reply button) for an incoming encrypted mail.

2. Select "Message | Run PGP..." (or push the key button).
This will decode the mail after removing the '>'-signs. (See 5a. Decoding).

3. Back in Eudora you have the decoded text with the '>'-signs inserted.

4. Now you can type your reply. When you're finished you can encrypt again. (See 5b. Encrypting).

5e. Clearsign a message

If PgpEudra cannot find an encrypted or signed message in an output window and you don't have a name in the "To:"-field, then it will clearsign your message. (PGP-parameters: -sta +clearsig=on)

Clearing the "Encrypt for" field in PgpEudra's dialogbox will also turn on clearsigning. If you had already a name in the "To:"-field, this is easier.

You can only sign for the first secret key in the keyring. This is because PGP needs a name whose key to use for signing if it is not the default. If you type anything in the "Encrypt for" field it will encrypt with that key (See 5b. Encrypting).instead of clearsigning.

Note 1: Before running PGP, PgpEudra sends two menucommands to the message window: "Edit | Select All" and "Edit | Wrap Selection". This will insert carriage returns in the text. If this is not done now, Eudora will insert them just before sending the message and the signature will fail because the text has changed. Eudora 1.4.4 does not have the Wrap Selection feature, so you'd better get the new version or you have to type carriage returns at the end of every line.
Note 2: This is done on every message in an output window .

5f. Checking signatures

If PgpEudra found a SIGNATURE BEGIN/END block it will pass this block to PGP and insert the text that PGP returns. This makes it possible to check more signatures in one message. After the first text has been checked it is returned in the message but without the SIGNATURE BEGIN/END BLOCK. The next time you run PGP the next message will be checked and so on.
You must check the signature on PGP's output. PgpEudra does not show anything.

5g. The "Edit | Undo"-function

If you've PGP'd and notice you've made an error, don't worry. The "Edit | Undo" menu selection restores the windowtext that appeared before PGP was started. As soon as you change anything in the text, you cannot undo the PGP action anymore, because the Undo function will undo that change, as usual in Eudora. Note that "Edit | Undo" is disabled when you're not in the part of the window, where the text is. So if the cursor is in the subject-field, first move to the text and then choose Undo.
You cannot undo an Add-key action.

5h. The Skip button

You'll see a "skip" button in the dialogbox, when PgpEudra found an encrypted or signed text (5a, 5f). If you push it, PgpEudra will move to the next PGP BEGIN/END block or to the next attached file. If it cannot find more of these, it will show a "Nothing to do" message.

6. PEICS.INI configuration file

You don't have to read this chapter unless you have special wishes. The default settings work fine for 80 % of the users, but for the others it's fine if they can change PgpEudra's configuration to their preferences.

PgpEudra first reads the file from the Windows directory, then from the program directory and then optionally from the directory specified by the command-line parameter for Eudora. The latter is usually used to give each user his own configuration.

Every time it reads an INI-file, it overrides the previous settings. This makes it easy to create a system-wide configuration and a user-specific configuration. So far there's no options dialogbox to change the settings. I'll add it when I've added some more options. I've included an INI-file with the default settings. If you agree with them you don't need the file because the program sets them internally before reading the first INI-file. You can check the settings (besides ProgEudora) by keeping the [CAPSLOCK] key down, while starting PgpEudra.

Here are the options that are currently supported (with their defaults):

In this section you can specify settings for PgpEudra and its interface to Eudora.
ProgEudora =
Here you can specify a program that should be run instead of EUDORA.EXE, if you need this. It will be searched in the same directories as Eudora. This setting will be read from the Windows directory (where most .INI-files are) or from PgpEudra's directory (where the program is).
UseToolbar = 1
A click on the button on the right side of the toolbar should start the "Run PGP..." dialog. You can disable this feature by putting a line "UseToolBar = 0" in the INI-file.
CopyToReadOnly = 1
Normally (if set to 1), PgpEudra will copy the decrypted text to a read-only window. If cleared (= 0), you're prompted were you want the text to go to (Clipboard or window), like in previous versions. Note that you can still "Select All" and "Copy" the text window to the clipboard. All operations that Eudora does (forward, save,..) are done on the original text.
AnsiOem = 0
If you turn this on, then PgpEudra will do an AnsiToOem conversion before creating the file for PGP. After PGP has run it does an OemToAnsi conversion.

You may need this if you use special characters as in French, German, etc. Windows uses the Ansi character set, while DOS uses the Oem definition, so if you exchange mail with someone who does not use Windows (they exist!) and if you use those special characters, then you can try to turn on this option. Then PGP will maybe not complain about failing signatures and you can better read PGP's output. If you don't understand, what this is all about, leave it as it is.

ConvertAttach = 0
This is really a beta option and that will not change soon. I turned it off internally, so if you like to use it, you should set this option to 1. Don't be surprised if it behaves different than expected. This has not been tested very well and there are many possible failures. On the other hand I did not write much new code for this, so I dared to add it.

Only incoming attachments can be passed to PGP. I added this because some other mailerextensions put the encrypted text in an attachment. Besides some keymailers send keys as attachment. The converted text will be put in the text in place of the "Attachment Converted: FILENAME" text. This enables you to decode more attachments in one message. Simply "run PGP" on them again.

The program reads the attached file and scans for a "-----PGP BEGIN" to see what it should do with the file. Then it does exactly what it normally does with a text in the window. It copies the text to a file (PGPEUDRA.ASC), passes that to PGP and inserts the result in the original text. If there's no PGP MESSAGE, KEY or SIGNATURE block in the file, then PgpEudra just ignores the attachment.

Now please don't start mailing me, that you cannot encrypt attachments that you make. I'll add this once, but don't ask when.

NickNames = 0
Normally PgpEudra does only do a NickName expansion if you keep the shift key down while starting the "Run PGP" dialogbox. If you set NickNames (=1), then nicknames will always be converted.
[PGP Settings]
In this section you can specify settings for Pgp and its interface to PgpEudra.
ProgPGP =
Here you can specify a program that should be run instead of PGP.EXE or PGP.PIF. It will be searched in the same directories as PGP. If you have Viacrypt's PGP, you can set its filename (optionally with path) here. (And don't forget to pay me if you use PgpEudra commercially ;-).
PGPtempdir =
You can set PGPtempdir to the directory where you want PgpEudra to create and read the files that PGP will process. This overrides the value set in the environment variables TMP and TEMP. If you set the value to a ram-drive, you'll be sure that there are no readable (PGPEUDRA/PGPEUDRA.ASC) files or chunks left on your disk. Besides access is faster.
Note: PGP creates its own temporary files in another directory. See PGP's documentation.
EncryptFor =
Here you can type your name. PgpEudra will add this name to the "Encrypt for" field when it has to encrypt a message.
KeepPassword = 0
If you set this option (=1), then PgpEudra will ask you for the password, and set it in its own environment. This should be passed to child processes, but it does not work (with PGP262i), so I turned it off internally.

Maybe it works with a 32-bit PGP. The program that starts PGP in the DOS-box, copies the environment for PGP straight from the system settings, not from PgpEudra. But a 32-bit PGP will be started directly by PgpEudra, so I think it should work.

I got a report, that it worked with pgp 2.6.3i compiled for win32. You can find pgp263i (beta) on the International PGP homepage ( On WinNT it works too.

In this section you can specify default flags for Pgp. There's still only one, but when the dialogbox gets options to choose, there'll be more.
AlwaysSign = 0
If you turn on (1) this option, then PgpEudra will sign every message, that must be encrypted, with the first key on your secret keyring.

7. Miscellaneous

7a. Programversions and name change

The versionnumber of PgpEudra increases by 0.01 on minor changes. Versions with new features get the next 0.x0 number. In this case the manual will be updated too. The timestamp always has the versionnumber. 1:00 means version 1.00.

Now you expect, this is a really new program, but it isn't. OK, the 32-bit program is, but functionally the change is not so big. I numbered this one 1.00, because then I have some numbers to upgrade the freeware 0.22, when necessary. Besides I wanted a disctinction between the freeware (0.xx) version and the free/share-ware (1.xx) versions. Maybe version 2.00 will be shareware only. Who knows...

PgpEudra(32) is compiled for i486 and runs on both 80386 and 80486 (and better) processors. PgpEudra(16) runs on a 80286 based computer too. Choose "Help | About PGP extension..." to get the "About PgpEudra" dialogbox. Here you can see which version you have (and who made this program ;-).

I renamed the programfiles, because "16" and "32" didn't fit in the 8 positions for the filename in good old DOS. Besides Philip Zimmermann has a trademark on the letters "PGP", so I maybe have to rename the program in the future. PEICS is short for Pgp-Eudora Interface by Comerwell Software. If that's acceptable I'll maybe rename PgpEudra. EPICS would be another option, but this has also been used for a conference and more.
BTW: You have already seen this name, if you've used the program before. It's at the bottom of the "Run PGP..." dialogbox.

PgpEudra(32) consists of 2 parts: an EXE-file (PEICS32.EXE) and a DLL (PEICS.DLL). This is the only way to do window subclassing between different processes in Win95. PEICS32.EXE hangs its DLL in Eudora's address space and the DLL does the actual interfacing. Direct interfacing between programs is not allowed.

The filesizes and dates in the actual ZIP-file may be a bit different, because I don't update this manual on every program update. You can use the file PEICS.SIG to check if you have the original files.
You need my public key (for for this. It's available from the keyservers, from Comerwell's homepage and by mail from There's just a "vacation" mailer, that sends a short information file with my key. Please type subject "key", because I hope to make a real keymailer once again. Your message will be ignored :-(, so you'd better not type any.

Receiving the key by mail is the easiest, if you've already installed PgpEudra, because PgpEudra can add the key to your public keyring.
To check the signature type at the DOS-commandline:

pgp peics.sig

and PGP will show if the file has been changed. Of course this is no guarantee for the correctness of the program. It only shows that it's not corrupted. This is a good virusprotection too.

The download page on Comerwell's homepage has links to the latest version. You can regularly check the announce page to see if there are new versions announced. Of course I'll post in the new newsgroup, when I have a new version.

7c. Useful links on the internet

This part will may be outdated soon, but you can use it as a starting point. The program is not on my homepage anymore because of an access limit of 100 MB per month. Instead my homepage has links to these ftp/http-sites:, U.S.A., USA-California, USA-Missouri, UK, Deutschland, Norge, Nederland, Australia, freebsd.
Note that these are URL's to the version you're reading about now. The filename in the URL has the version number in it, so you'd better search for PGPEUDRA???.ZIP.

If you need information about PGP or about other shells, you may find these links useful:

7d. A brief history

For those interested, here's a brief history. Others read "Copyrights, licence & disclaimer". I first thought about writing this program when I saw someone struggling with both Eudora and PGP in spring '95. I looked for some PGP-shells, but couldn't find anything really convenient. It should be easier. The friend who worked with both programs learned to handle them and did not really need it anymore.
17th november 1995:
At 11 p.m. I decided to write the program. Now another friend had some real problems with this situation and worse, I got binhex- encoded files that were hard to decode on my Linux system. Of course this could be solved in any way, but now I thought it would be better to make life easier.
Version 0.12:
6th December: This was the first publicly available version after some testversions for friends only. It has just the basic features like encoding, decoding and adding a key. No special PGP-features like signing messages.
Version 0.13:
The previous version did not run with Eudora light 1.52, so I had to work again. Bad news for me, that QUALCOMM changed a lot. All windows' classnames have changed.
Version 0.14:
Added more relaxed name checking (-r option). Removed in version 0.22.
Version 0.15:
The "Edit | Undo"-function works with Eudora Light, too. And I added an extra check on the window where the text should go to after PGP has run. Someone reported that he got this text the wrong window.
Version 0.20:
+Clearsign text and check signatures
+Pass command-line options to Eudora
+Scan for key after decoding
+Choose where to copy decoded text (clipboard or window)
Version 0.22:
+Some bugfixes
+Better error reporting
Version 1.00:
+32-bit version
+button on toolbar
+INI-file with some new options

7f. Why free software?

"Why not?", you would probably ask. Well, it's a lot of work to write a good program and you need to buy some compilers, tools and libraries that are often not freeware. On the other hand I'm happy that PGP is freeware. I think this has been very important to make it the standard for encryption.

I use Linux (Unix for 386 PC's) and the mailprogram Elm, which are freeware, and I had been thinking about adding PGP-support to Elm, but they have already done this, so that saves me a lot of time. Besides I think more people will use PGP if it can be done very easy.

The availability of a freeware version ensures that bugs are found soon, which makes the software more attractive for commercial use. If this program would be only sold it would be running only on a few systems in even less different configurations and it would take much more time to find bugs.

If you like to support my programming efforts, you're very welcome to buy a license for non-commercial use. It's half of the price for commercial use, so f25,- (about $15) for a single copy license. Add 17.5% VAT and payment costs. You get the same rights as the commercial license holders, except that you should not use the program commercially. People outside the EU do not have to pay VAT. Instead they have to import the license, which could imply they have to pay local taxes.

7g. Commercial use

If you want to use this software commercially, that is, in your company, at a governmental or educational institution, then you should consider this software as shareware. PgpEudra supports Viacrypt's PGP, although I cannot buy that program because of USA export restrictions.

I do not sell the program. You can get it from the internet, yourself. This means, you can easily get the latest version. For me it saves a lot of time and administrative work. I like programming much more.

Instead I sell a license to use the program. This no-nonsense license offers you:

A license for 1 copy costs f50,- (Dutch guilders), which is (now) about $30. Every additional additional copy will cost f10,- extra. Please add costs for payment and 17.5 % VAT (Value Added Tax). Companies can get an invoice, which will save them the VAT. Companies outside the EU do not have to pay VAT. Instead they have to import the license, which could imply they have to pay local taxes. Contact me for site licenses that exceed 50 copies. Don't forget the e-mail address on the note for your registration. Otherwise I'll not know who paid.

7h. Remarks, comments, questions, etc

Remarks, comments, good ideas and mental support are very welcome. Maybe I cannot reply soon, sometimes, because I have some work to do and I don't know how much mail this will generate, but I'll try to answer. If you have a question, please read the FAQ before sending mail to me. I don't like to answer the same questions all the time.

I don't like to get large attached files by mail, because I have a slow and expensive line to the internet. If you want to send me large files ( > 50 kB ) please do to and mail me to tell that you put something there. You cannot read from this directory, so you cannot use it for your own disk storage ;-(.

This program is not complete, yet. I think, I'll add some features in a future version. This distribution comes with a file "TODO.TXT", that describes some features, that I like to add. I don't pretend to make a complete shell, though.

The bugs page has information on bug reports and fixes.

Please send mail about this program to I still like to find my personal mail if this program gets very popular ;-).
