The following files are contained on this diskette:

The Private Line (tm) is a full implementation of the Data Encryption
Standard, published by the National Bureau of Standards, U.S. Department of
Commerce. This command line and/or menu-driven program works on IBM
PC/XT/AT, PS/2 and compatibles with MS-DOS 2.0 or later. It will encrypt
any MS-DOS file, including LOTUS 1-2-3, dBase II/III, WordStar, etc.
Single and double encryption is provided, along with program options to
convert a file from binary format to printable ASCII for use over
CompuServe or EasyLink and other bulletin boards. Files may be deleted or
purged. Only 64K is required. Pathnames are fully supported. An option
is included to demonstrate compliance with the 171 tests required by the
NBS. Compliance is also checked during program initialization. This
program is shareware and requires a $30 registration fee for continued use
after evaluation.
Private.Doc - A full 46-pages of clear, easy to follow instructions on the
use of The Private Line. A table of contents is provided, in addition to a
bibliography. The document was printed using WordPerfect 4.2, with page
length set to 64 lines and with 52 lines of actual text. It is an ASCII
file.
Msg.Dat - This is a sample file which contains information about The
Private Line. It also contains the 171 tests required by the National
Bureau of Standards to insure complaince with the Data Encryption Standard.
Msg.Enc - This is the same file encrypted with the key,
7C,A1,10,45,4A,1A,6E,57, using electronic codebook mode without padding.
Version 6.01 fixed a bug in the ECB padding routine.
Version 6.02 added the capability to disable the speaker. Several users
have voiced their dislike of the beeps each time the program is waiting for
user input. The default is speaker disabled. The user may enable the
speaker from the Additional Options Menu and change the default by saving
the selected options.
Version 6.02 also changed the key to return to the previous menu. In
previous versions, Control-R was used. Beginning with this version,
ESCAPE, will back the user out of each operation, except for the List
Directory option while the directory is being input by the user. This
change is downward compatible; Control-R continues to work.
Version 6.03 includes the display of the current directory when the program
is waiting for a file name. The hi-light bar may be moved by using the
arrow and page up/page down keys. The high-lighted filename may be
selected by pressing RETURN. The desired filename may still be entered by
typing it and/or the associated path. If the user begins typing a file
name, the high-light bar may still be moved, but when RETURN is pressed,
the filename used is the one entered by the user, not the one under the
high-light bar. If a filename entered by the user is erased by using the
backspace key, then the filename under the high-light bar may once again be
selected by pressing RETURN.
Version 6.04 increased the number of filenames from 10 to 50 which are
displayed when the program is waiting for a filename to be entered by the
user. Version 6.04 also added the use of hexidecimal keys from the command
line.
Version 6.05 corrected a bug found in the non EGA environment.
Version 6.06 corrected a bug found in the CGA environment.
Version 7.0 added screen memory write routines for the master and additional
option menus, the opening and closing screens, the directory display and for
the screens from which the filenames contained on the current directory are
displayed.
