Contents of the READ.ME file
This file accompanies a set of programs to support a personal encryption
system for use with IBM-PC compatibles running MS-DOS. The encryption/
decryption process is symmetric and takes only a few seconds for one or two
pages of text. Very large files take a significant length of time to convert.
The source files for "tangle.com" and "untangle.com" are "tangle.c" with the
ENCRYPT constant set to 1 or 0 respectively. Since not all users may have
access to the Turbo-C compiler, executable versions are also supplied. The
file "tangle.doc" is a user manual. A description of the algorithm is given
in "algthm.txt", and the author's address in "author.txt". The file "dir.cpt"
is a directory of the disk (without itself listed) encrypted with the password
"abracadabra". You can untangle this file and check file sizes etc.
