#50# 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. #51# 旼컴컴컴컴컴컴컴컴컴컴컴컴커 � Commonly Asked Questions � 읕컴컴컴컴컴컴컴컴컴컴컴컴켸 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. #300# HISTORY OF REVISIONS: 袴袴袴袴袴袴袴袴袴袴� EZ-Crypt Lite ver 1.0 Initial release.
