3 WHAT IS MailPGP?

MailPGP is a simple user interface for Philip Zimmermann's Pretty Good Privacy
(PGP). I made this program only because I couldn't find a decent PGP shell to
use with my e-mail program. 
MailPGP is easy to use and still has many advanced features. If you only want
to keep your mail secure, just ignore all the settings and you'll do fine. For
more information on the available options, see part 4 (Instructions).
With MailPGP you can write the mail with your favorite program, cut the text
to the clipboard (Ctrl-X), write the recipient to MailPGP, check encrypt and
hit proceed. Then you can simply paste the encrypted text to your e-mail and
send it. No messing with too many options or multiple editors. Hope you like
it.


+--------------------------------------------------
4 INSTRUCTIONS


4.1 Configuring PGP and MailPGP
+------------------------------

    MailPGP requires PGP 2.6.x or newer properly installed to your system. 
    You can obtain Pretty Good Privacy i.e. from The International PGP Home 
    Page: http://www.ifi.uio.no/pgp/

    PART 1. Configuring PGP environment, complete instructions are included
            with PGP:

      add the following lines to your autoexec.bat:
      SET PGPPATH=C:\PGP
      SET PATH=C:\PGP;%PATH%
      (replace C:\PGP with the directory where you copied the PGP files)

      You also have to add time zone information to autoexec.bat; see more
      precise instructions from setup.doc that came with PGP.

      For example, Finland:      SET TZ=EET-2DST
                   Los Angeles:  SET TZ=PST8PDT
                   Denver:       SET TZ=MST7MDT
                   Arizona:      SET TZ=MST7
                   Chicago:      SET TZ=CST6CDT
                   New York:     SET TZ=EST5EDT
                   London:       SET TZ=GMT0BST
                   Amsterdam:    SET TZ=MET-1DST
                   Moscow:       SET TZ=MSK-3MSD
                   Aukland:      SET TZ=NZT-12DST


    PART 2. Using MailPGP

    All the installation needed is to copy MailPGP.exe to a directory of your
    choice.

    First you'll need to create yourself a PGP key (if you don't already have 
    one). Start MailPGP, click the right mouse button, select Create a new PGP
	key from the pop-up menu and follow the instructions.

    If you want MailPGP to automatically use a specific secret key for signing
    messages (and for extracting a public key), type the desired user ID to 
    Userid(s) field and select Set as default user ID from the pop-up menu.
    For more information, see Sign and Only Sign from part 4.2. (The Available
    functions).

    After that, you'll need to add your friends' public keys to your key ring.
    You can easily do that with MailPGP by copying the key to clipboard and 
    clicking Proceed. When MailPGP finds a PGP key from the clipboard, it adds
    the key to your key ring (after asking you and assuming that Ignore keys 
    isn't selected). You can try this by adding my public key (included) to
	your key ring . Open SAMIT.ASC i.e. with Notepad and copy its contents to
    clipboard. Then start MailPGP, click Proceed and follow the instructions.

    To extract your public key from the key ring for sending it to your 
    friends, select Extract public key from the pop-up menu. If you didn't 
    define a default user ID, you'll need to type your user ID to Userid(s)
    field. There you go, your public key is waiting for you in the clipboard.
    You can extract any public key in your key ring just by typing the desired
    user ID to Userid(s) field.

    To encrypt a file, check the Select a file option, choose whether you want
    to encrypt (and sign perhaps) or decrypt and click Proceed. A dialog will
    appear that allows you to choose a file. After you've chosen a file and
    clicked OK, the file will be en/decrypted. Notice that the original file
    isn't deleted. If you have selected to use conventional crypting for files
    (from the Settings dialog), you don't need to type in a user ID.

    If you want to verify that MAILPGP.EXE hasn't been modified by anyone
    except me, type "pgp mailpgp.sig mailpgp.exe" while in DOS
    prompt. You should get a response from PGP similar to following:

       File has signature.  Public key is required to check signature.

       File 'mailpgp.sig' has signature, but with no text.
       Text is assumed to be in file 'mailpgp.exe'.
       .
       Good signature from user "Sami Tolvanen <samit@sip.fi>".
       
    If you get a bad signature, it means that the file has been modified. Check
    the file with a virus scanner for a possible virus infection and download
    MAILPGP1.ZIP from the MailPGP Home Page to make sure that you get the
    original file (see part 6). If you continue to have problems with checking
    the signature, e-mail me.


4.2 The available functions:
+---------------------------

    (more information on PGP functions can be found at the International PGP 
    Home Page)

        Generates a new PGP public/secret key pair.

      Set as default user ID:
        Sets the user ID in the Userid(s) field as the default user ID. The

        ID as the default user ID.

      Empty Clipboard:
        Clears all clipboard data.

    -------------------

    -------------------
    SETTINGS DIALOG:
     Encryption:
      Pause after encrypt:
        Pauses PGP screen after encrypting so that you can see what happened.
        As default this option is not selected.

      ASCII armor encrypted files (-a):
        Uses ASCII (-a) switch when encrypting files. If you use this option
        you can i.e. easily send an encrypted text or binary file via e-mail.

      Copy ASCII armored files to clipboard:
        If you select this option, all the files you encrypt using the ASCII
        option will be copied to clipboard.
        As default this option is selected.

      Use conventional crypting for files (only IDEA):
        Uses only IDEA to encrypt a file. Requires that you set a password
        for a file.

     Decryption:
      Pause after decrypt:
        Pauses PGP screen after decrypting so that you can see what happened

        key ring.
        As default this option is not selected.

      Leave temporary files:
        If you want the files that PGP creates not to be removed after use,
        select this option.
        As default this is not selected.

      Save pass phrase in memory:
        Saves your pass phrase in memory so that you have to type it only
        once. Pass phrase will stay in memory until you quit MailPGP. Notice
        that your pass phrase won't be saved to disk.

        Sign message that's going to be encrypted. MailPGP will use the
        default user ID if it is defined. If not, PGP uses the secret key
        that's most recently added to your secret key ring.

      Only Sign:
        Sign message. You can type the sender to Userid(s) field, if you 
        don't, MailPGP uses the default user ID. If default user ID isn't
        defined, PGP will use the key that's most recently added to your
        secret key ring.

        selected, checks the signature.

    -------------------

      Userid(s):
        Type here the user ID for encryption or extracting a public key, or 
        the sender for signing. If you leave this field blank when signing or
        extracting a public key, MailPGP uses the default user ID if it's been
        defined.

      Select a file:
        Check this if you want to en/decrypt a file instead of the clipboard
        contents.

      Proceed:
