- 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.
