To begin execution of PC-CODE1 or PC-CODE2, just type these names
in PC DOS or type PC-MENU. For example: "A> PC-MENU "
PC-CODE1 is intended to encode/decode files only. It does this
thru a process known as super-encipherment. This means that
each character of plain text (uncoded text) is both scrambled
(transposed) as well as substituted for some random "other"
character.
Keys may Optionally be Loaded or Saved to a FILE. The data format
of such a file is 25 KEY numbers (between 1 & 2,147,483,646)
each separated by A Carriage Return (on separate lines); And
finally a 26th line of required Comment/Remark Information.
An example of a key file is "SAMPLE.KEY". You can display
this file by typing one of the following in DOS.

If a key file is not used the following discussion applies:
There are two levels of security "LOW" and "HIGH". If you
elect the LOW level you will only have to enter 7 key
(SEED) numbers or in the case of alphanumeric keys 7
passwords of 5 or more characters. Actually, the longer
the passwords - the better. An Ideal password length would
seven passwords of 8 characters each.
If you elect HIGH security be prepared to enter up to 25
numbers between 1 and 2,147,483,646; or a minimum of 180
=======================
Wish More Documentation (Yes or No) <CR>=yes:

P C C O M P U T E R S E C U R I T Y V1.51 PC-CODE1
characters of alphanumeric passwords. It is best, the first
time thru to elect LOW security for testing purposes.
Why so many characters are required in the HIGH ALPHA mode security
is due to the additional insecurity of letters/words/phrases
and that the Randomizing (hashing) routine requires 6 characters
to generate a uniformly random Number (used internally). If the
users' alphanumeric passwords were perfectfully random and
all 256 possible characters could be typed at a 47 key keybroad,
there would only be a need for 4 characters to generate this number.
The user must provide a series of keys (a minimum of 7) which
may either be numeric (i.e. characters "0123456789") or
alphanumeric which includes any character on your IBM PC
keybroad. This includes alphabetics, numerics, and special
symbols like "!@#$%^&*()=+?:.<>[]~{}" and so forth.
Each of these keys should be chosen at random, and each
should be different. For alphanumeric keys, the following
