OzCIS PGP scripts
~~~~~~~~~~~~~~~~~
DISCLAIMER
~~~~~~~~~~
Since these perl scripts are FREE, they are provided AS IS. I MAKE NO
WARRANTY OF ANY KIND, EXPRESSED OR IMPLIED, INCLUDING WITHOUT LIMITATION,
ANY WARRANTIES OF MERCHANTABILITY AND/OR FITNESS FOR A PARTICULAR PURPOSE.
Introduction
~~~~~~~~~~~~
This is my way to get PGP to work with OzCIS. It may not be the perfect
solution for you, since it uses quite some memory.
I do not garranty that these scripts are bugfree. This was my first experiment
with perl, so it is very well possible that things can be done better. If you
find any bugs, please mail me a detailed description so I can fix it. Better
yet, fix it yourself and mail the fix to me. :-)
Features
~~~~~~~~
The Decryption script will decrypt a all messages in the message file. All keys
that are in the message file will also be added to your public keyring.
The encryption script will encrypt all messages in your rely file. It will not
encrypt messages that start with "#leave" on the first line. The script will
try to get the recipients address from the header that OzCIS gives. The it will
check your keyring to see if such a key exists. If it exists, it will encrypt
and sign the message, if the address is not found, the message will only be
signed. Messages that allready are encrypted or signed are left alone.
Just in case something goes wrong, both scripts make a backup of the original
file processed. If security alows it, it may be a good idea to put PGPPASS in
your autoexec.bat (DOS) or config.sys (OS/2). That saves the trouble of typing
your password everytime. ONLY DO THIS IF YOU THINK IT IS SAVE ENOUGH.
Installation
~~~~~~~~~~~~
DOS: Requirements: - DOS version of PGP
- DOS version of Perl.
I don't know if it will work under DOS, I didn't test it. It might be a
problem since DOS has limited memory, and OzCIS, PGP and perl must fit
in memory at the same time. But if you want to try it, just edit your
OZCIS.INI so that the lines
ReadPreProcess=
CompPostProcess=
become
ReadPreProcess=perl -x ozpgpd.cmd
CompPostProcess=perl -x ozpgpe.cmd
You can also change the scripts a little to make them a .BAT file which
calls perl to execute itself. See the perl documentation on how to do that.
NOTE: Perl and pgp must be in the path, and the full path name of the
scripts must be given. In this case is assumed that the scripts
are in the current directory (the OzCIS directory).
OS/2: Requirements: - OS/2 version of PGP
- OS/2 version of Perl
- os2exec
This is the only system that the scripts are tested on.
Change your OZCIS.INI so that the lines
ReadPreProcess=
CompPostProcess=
become
ReadPreProcess=os2exec ozpgpd.cmd
CompPostProcess=os2exec ozpgpe.cmd
NOTE: Perl, pgp and os2exec must be in the path, and the full pathname
of the scripts must be given. In this case is assumed that the
scripts are in the current directory (the OzCIS directory).
I think a similar way should exist to get it working under NT.
Final notes
~~~~~~~~~~~
Please don't fall to hard on me for any errors in this text. English is not my
native language. If you find any errors in the script or in this readme, please
tell me so that I an fix it. Any comment is welcome.
