This document is meant for those who wish to configure BlueKey to fit all
their needs, and for those who need to know more about BlueKey. If you
haven't installed BlueKey yet, do so now and then read this file.

┌──────────────────┐
│ Additional Files │
└──────────────────┘
While running, BlueKey works with several files it writes to your disk,
which were not included in the original archived file:
BLUEKEY.CFG - The main configuration file BlueKey works with. This file
is written when you exit BKSETUP and is being updated by
BlueKey.
HISTORY.DAT - This file keeps the list of the userids you chose to encrypt
to in this menu before.
GROUPS.DAT - Keeps the groups definitions.
BLUEKEY.TM* - These are files BlueKey opens, closes and deletes during any
run. In case you find such files on your disk, it means some
error probably left those files there. Remove them, there's
no need for these files.
┌──────────────┐
│ "MyName" │
└──────────────┘
PGP's MyName keyword is used by BlueKey when self-encrypting messages. Users
can choose between two userids either by the "Change userid" option on
BlueKey's menu or by including the switch /u1 or /u2 on BlueKey's command
line.
┌──────────────┐
│ Encryption │
└──────────────┘
When you choose to encrypt a message, these are the procedures BlueKey runs:
First, the message will be stripped of tearlines, taglines and the origin
line. These lines will be added back once the message itself was encrypted.
BlueKey will also try to identify and remove your signature if you specified
the name of your signature file in setup. If you have your signature in
a template, consider copying it to an external file as well.
The recipients should be on BlueKey's command line. It is also possible to
pick recipients by using BlueKey's MultiEncryption menu.
Then BlueKey calls PGP for encryption. Output file is kept in an ASCII
format.
┌─────────────────┐
│ MultiEncryption │
└─────────────────┘
BlueKey's MultiEncryption menu allows the user to tag userids from three
sources: The history list, the keyring and the groups definitions. Simply
copy the userids from the lists (by using the Right Arrow key, or by tagging
and clicking on the arrow) to the "EncryptTo" window and that's it.
This menu is also meant to configure the groups definitions. You can copy
any userid to an existing group, or add new groups and userids in the
Groups screen.

┌──────────────┐
│ Decryption │
└──────────────┘
As you probably know by now, BlueKey can be used on reply messages. It is
the only way to run it in Blue Wave, and it is optional when installed in
Termail.
If BlueKey decryption command is run on a reply message, BlueKey will run
a viewer after decrypting the message, in order to allow you to read the
decrypted message. You can then choose to reply or exit. When you choose
to reply, BlueKey will reformat the text, and produce a regular reply
message, with all the quote signs and lines in place.
If the original message contains other text than the pgp encrypted lines,
BlueKey will put it in place.
If the message is not a reply message, the user will not enter the viewer.
Instead, your editor will present you with the message, ready for editing.
BlueKey's decryption command can also be used for checking signatures on
PGP signed messages. This feature is for use in Termail and GoldED alone.
In order to check signatures in Blue Wave, you should use SignChk, another
MasTic product, which replaces your Blue Wave external viewer. Check out
"Distribution" in BLUEKEY.DOC to see where you can obtain the newest
version of SignChk (sigchk*.*).
┌──────────────┐
│ Signatures │
└──────────────┘
BlueKey can either clearsign ("/s" on the command line or choosing "S" on
the menu) or sign ("/i" on the command line or choosing "I" on the menu).
Clearsign means signing your message in a way that keeps the message readable
without running PGP. Signing your message means you should run PGP to
check the signatures.
Output file is kept in an ASCII format.
To learn how to check signatures in BlueKey, read the last paragraph of
"Decryption" in this document.
BlueKey also offers an option to sign and encrypt a message ("/b" on the
command line, or "B" on the menu). This is the same as encrypting a message,
but PGP will sign the message before encrypting it. Refer to "Encryption"
in this document to learn more about encrypting using BlueKey.
┌───────────────────────┐
│ Import/Export of Keys │
└───────────────────────┘
Export key from message
This option ("/1" on the command line or "1" on the menu) will add a key
(which is given in ASCII format in a message) to your keyring. This option
is used only for this specific purpose. Refer to PGP documentation to learn
more about this option.
BlueKey's Advanced Document Page 4
──────────────────────────────────────────────────────────────────────────────
Import key to message
Use this option to ("/2" on the command line or "2" on the menu) import a
key from your keyring in ASCII format. This will prompt you for an userid
and will then append the key to the end of your message. This option does
NOT sign your message. Refer to PGP documentation to learn more about this
option.
┌──────────────┐
│ Backup │
└──────────────┘
BlueKey backs up your files before running any PGP command. The backup file
is named "msgtemp.bak". In BlueKey's menu, you can choose to keep the backup
files when exiting BlueKey. This will cause security problems, and you should
be aware of the risk of leaving text files, possibly decrypted, on your disk.
┌──────────────────┐
│ Editors' Choice │
└──────────────────┘
(No, BlueKey has not yet been announced as an Editors Choice product. This
chapter discusses the preparation of a multi-editors choosing batch file.)
If you'd like to have a set of editors to choose from when writing a message,
then one easy way would be to create a batch file to achieve this purpose.
Edit a file with the extension BAT, for instance EDITOR.BAT and enter the
following commands:
[batch file]
@echo off
choice /c:123 "(1 - BLUEKEY, 2 - Q, 3 - EDIT.COM) "
if errorlevel 3 c:\dos\edit %1
if errorlevel 2 c:\qedit\q %1
if errorlevel 1 bluekey.exe %1
Change the names of the editors to fit your needs. Then change the editor
command of BlueWave/Termail to the batch filename, i.e. EDITOR.BAT. Then,
when running the editor command, your reader will present you with the
line in quotes. Press the number of the editor you'd like to work with,
and that's it.
