Quick startup info:
EZ-Crypt Lite allows you to encrypt and decrypt files. This means it
allows you to limit the distribution of your important information to a
restricted group of people. EZ-Crypt Lite will give you the ability to
make your important information unintelligible to those who don't have a
"need to know". ONLY those with the correct decryption key can access
your important data.
EZ-Crypt Lite provides four methods for privacy of communication. First,
the simple or fast operation which is basically an exclusive or. Second, a
form of substitution. Third, a form of transposition. Fourth, a slower
combination of substitution and transposition. EZ-Crypt Lite also performs
analysis on your data which can be used to check your encrypted output.
Some people are interested in determining what a message said. Those
people can use the analysis capability to determine what form of cypher as
well as try to break the key of an encrypted message. Efforts at reading a
secret message is called cryptanalysis.
Refer to other sections of the On-Line Manual for additional information.
F1 is always available to call up help while you are using EZ-Crypt Lite.

┌──────────────────────────┐
│ Commonly Asked Questions │
└──────────────────────────┘
1. Does EZ-Crypt Lite (EZCRL) allow me to send software thru the mail
without worrying about unauthorized people getting access to it? Yes!
Both you and the person you are sending the files to need a copy of
EZ-Crypt Lite and the common shared key. Before sending the files thru
the mail, encrypt them using the highest encryption method in EZ-Crypt
Lite (this provides the maximum protection). At the receiving end they
will decrypt the file using the same method and the common key.
2. Can I be sure that no one will ever be able to "read" my encrypted
data? No! All that you can do is make it extremely difficult for
anyone to have access to your data. Your goal should be to make it
more costly for someone to gain access to your data than the data is
worth. EZ-Crypt's encryption methods can be broken but it is very
costly to break the higher encryption methods within EZ-Crypt. It will
cost someone hundreds or thousands of hours of manpower and computer
time to "crack" the higher encryption methods that EZ-Crypt provides.
#100#
EZ-Crypt Lite requires an IBM PC or close compatible with at least 384K of
RAM and DOS 3.0 or later. A hard disk is not required but is recommended
when encrypting/decrypting large files because of the much faster disk
access.
EZ-Crypt Lite provides several encryption/decryption methods for you to
choose from. We are not trying to confuse you with extra choices.
Depending on the type of data you are working with a simple but very fast
method may be all you need. As your need for more protection increases
you can use the slower but safer encryption routines we provide.
#200#
The use of coded messages for secret communications has been a practice
throughout history. Julius Ceasar sent coded messages to his general to
ensure the messages couldn't be read if they fell into enemy hands.
George Washington, during the Amercian Revolution, passed important
information about the British forces in coded form. Today, the US Military
and many large corporations pass important information in a coded or
encrypted form.
The ability to communicate is very important. But there will be occasions
when you may want to limit your information. To limit the number of people
who can read your important information, EZ-Crypt Lite will encrypt and
decrypt your files. You can store or transmit those files to communicate
and still keep your information unintelligible to others.
Some individuals may be interested in determining what your message said.
If this individual obtains a copy of your encrypted message, he will
attempt to determine what your message said. Your message is considered
safe as long as it will take too long to unravel the message, for it to be
useful to the other person.
Some of the fundamental understanding of basic cryptanalytic endeavor, is
taken up in the manual.
#201#
Some basic definitions follow:
Cryptography -- The general study of hiding the meaning of messages and
the general techniques used for the hiding.
Cryptanalysis -- The solving or breaking of codes without any knowledge of
the key.
Cipher -- Any technique, method, or scheme (substitution, transposition,
and XOR) used to encrypt and decrypt text, without regard to its linguist
structure.
Plaintext -- The unencrypted or totally decrypted readable text.
Cyphertext -- The unintelligible text, after encrypting it.
Encrypting -- The process of encoding a plaintext file to hide the
intelligence.
Decrypting -- Decoding an encrypted/ciphertext file.
#202#
Some more basic definitions follow:
Key -- The text that was used to encrypt or decrypt a file. Sometimes
called a code word.
Substitution encipherment -- Replaces each letter of the original message
by another.
Transposition encipherment -- Rearranges the position of each letter of
the original message, but doesn't change their identities.
XOR -- Exclusive or, an arithmetic encryption technique working at the bit
level on characters.

GENERAL:
════════
1. EZ-Crypt was developed by David Black and Perry Kelley.
2. Special thanks to all of our Beta testers.
3. EZ-Crypt Lite was written in C and uses the Professional C Windows
described below. The source for EZ-Crypt Lite consists of about 5,000
lines of code.
4. Special thanks to Jim Nech at SSS for his excellent C & Assembly
language windowing package (Professional C Windows) used in EZ-Crypt
Lite. It comes with complete source code and is only $89. This
package is a must for software developers (info/orders 713-943-8060).
