DIGITAL CRYPTO PC-IRIS, PC-MERLIN, PC-LOCK
------------------------------------------
Overview
--------
IRIS implements data encryption using RSA, DES, VERNAM, PLAYFAIR, BAZERIES,
VIGENERE, ADFGVX, LITTLEWOOD algorithms.
MERLIN implements the DOS 'copy' function but with DES encrypted output.
LOCK implements a simple session lock facility, preventing unauthorised
use of a PC while the user is absent.
Distribution Disk
-----------------
The IRIS distribution disk contains the following files:
IRIS.EXE - The PC-IRIS program
IRIS.HLP - On-line help file
IRIS.DAT - Permanent default file
KEYS.DAT - Sample cipher key file
ENCRYPT.BAT - A quick interface to IRIS for file encryption
DECRYPT.BAT - A quick interface to IRIS for file decryption
READ.ME - Last minute notes / revisions
REGISTER.DOC - Registration details and order form
DEMO.BAT - DES encryption and MAC demonstration
OZY.TXT - Text file used by demo
SWIFT.MSG - Text file used by demo
INSTALL.BAT - Installation procedure
MERLIN.EXE - Encrypting COPY clone
MERLIN.DOC - Ascii documentation for MERLIN
LOCK.EXE - Session lock facility
LOCK.DOC - Ascii documentation for LOCK
Installation
------------
The INSTALL procedure will create a directory '\IRIS', and copy the required
files into it. The command format is:
INSTALL source-drive target-drive
If you have a hard disk C:, load your distribution diskette in Drive A:,
and issue the command: A:INSTALL A C
If you are using a twin floppy machine, just copy the distribution diskette,
store the distribution as backup and use the copy as-is.
We recommend that you modify AUTOEXEC.BAT to include C:\IRIS in the PATH, if
you choose not to include C:\IRIS in the PATH, then you will have to CD \IRIS
before you run IRIS.
The ENCRYPT and DECRYPT batch files
-----------------------------------
ENCRYPT.BAT and DECRYPT.BAT provide an quick interface to IRIS for DES file
encryption and decryption. Usage is thus:
ENCRYPT filename DES-key or DES-keyphrase
DECRYPT filename DES-key or DES-keyphrase
Eg:
ENCRYPT ozy.txt 43-23-F9-C2-55-7E-1F-B3
DECRYPT ozy.txt 43-23-F9-C2-55-7E-1F-B3
Or:
ENCRYPT ozy.txt bewaretheidesofmarch
DECRYPT ozy.txt bewaretheidesofmarch
Release notes
-------------
The release notes for IRIS are available via the on-line help, under help
topics 'v4.1_release', 'v4.0_release' and 'v3.7_release'.
Documentation
-------------
Documentation is provided in the form of the on-line help system. The help
file, IRIS.HLP, is not printable. To create a printable documentation file,
issue the IRIS command HELP /EXTRACT. This will create the file IRIS.DOC,
which may be printed via the usual DOS commands.
Registration
------------
Registration details may be found via the on-line help under 'registration'
and also in the file 'REGISTER.DOC'.
