- 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'.
