UPDATING
This version features a new script that decrypts a email and overwrites the
original (the encrypted email). This has the advantage that you can read the
email with YAM. You can alse extract files that were appended to the email
before it was encrypted (so the appended files are encrypted, too).
Attention:
As the original message is overwritten by the decrypted one, anybody who has
access to your computer can read it easily. If you don't want anybody to read
your personal messages, Use ReadMail.rexx.
DecryptMail was written by Roberto Ragusa <r.ragusa isnet.it>
INTRODUCTION
The use of PGP is not easy for beginners, and also if you are used to the
commands of PGP, you have to use it manually, what is uncomfortable.
If you want to sign or encrypt an email, you had to write you text with any
editor, encrypt the text (you have to know the user-id of the recipient),
start your favorite mailer and include the encrypted text.
Why not write the text for your friend with the mailer (YAM) and sign,
encrypt, sign & encrypt or read the mail with an arexx-script and select the
recipient's user-id from an requester?
These arexx-scripts and commands give you the possibility to do such things
very easily.
REQUIREMENTS
As I think anybody who uses his Amiga seriously has WB39, it's required :-)
If you don't have V39, GRADE UP! We live in the nineties. (One should have
V46 by now, but it's not available:-(((
Same goes for MUI. If you're using YAM, the sublibraries of MUI that are
needed by SelectPGPKey are loaded already.
It seems that PGP versions previous to 2.6.3(i) do not understand the -
option which I use to read the recipient's ids, so you should upgrade to at
least this version.
And of course you need YAM.
INSTALLATION
Easier than it looks!
Copy all files except the .readme to YAM:rexx. Now you have to edit
all the scripts.
Change the variables: pgppath, userid and pubword
userid = 'Michael Praschl': Give your name here, if you want to encrypt
messages with your key, too, so that you can read them when they are in the
send-folder of YAM.
pgppath: set this to the path, where your pgp-executeable is.
Now edit YAM:.config and make the following entries in the last lines:
RexxMenu0 = YAM:rexx/SignMail.rexx
RexxMenu1 = YAM:rexx/EncryptMail.rexx
RexxMenu2 = YAM:rexx/SignEncryptMail.rexx
RexxMenu3 = YAM:rexx/ReadMail.rexx
Then you have the scripts in the arexx menu of YAM.
You should also set the pager to Multiview or MuchMore in pgp:config.txt:
Pager = "c:more"
This is not necessary, but helps you when reading encrypted mails.
USAGE
Signing a mail:
Select the mail to sign and select Sign.rexx from the menu. You will be
prompted to enter the mantra of your pgpkey in a window where pgp makes it's
input/output.
Encrypting a mail:
Select the mail to encrypt and select Encrypt.rexx from the menu. A
requester will show you all public keys you have. You may select one or more
keys. This requester was done with MUI. Then you will have to enter the
mantra of your pgpkey. If you closed the requester, pgp will ask you for a
receipient's id after you entered your mantra.
Signing and encrypting a mail:
Select the mail and SignEncryptMail.rexx ... (You should know how it works).
Read an encrypted mail:
To read an encrypted mail select the mail to read an select ReadMail.rexx
from the menu (yawn). When you have set you pgp-pager to Multiview or
Muchmore or something similar, the plaintext will be displayed with this
proggy.
This package will be obsolete, with YAM release V2.0
