F.E.D. is a DOS program to encrypt and decrypt all kind of data files (*.txt, *.exe, *.zip, ...), based on a single private key (password). So if you want to safe guard any files, and have an exclusive access to them, then this program is a good solution to that problem ! >> What is encryption ? Encryption is the transformation of data into a form unreadable by anyone without a secret decryption key (password).Its purpose is to ensure privacy by keeping the information hidden from anyone for whom it is not intended, even those who can see the encrypted data. For example, one may wish to encrypt files on a hard disk to prevent an intruder from reading them. >> How does F.E.D. works ? F.E.D. uses the best and oldest known form of encryption : encryption with a private key (password) - that is used to conceal data with a set of mathematical transformations. This method of encryption is "almost" unbreakable, because there are enormous combinations for building a private password, and the mathematical formulas for the data transformations are not to be in public knowledge. "The longer is the password the most secure is the encryption !" |----------------------------------->Џ * Ў<------------------------------------| [ How To Use F.E.D. ] ******************* To use F.E.D. the user has two possible ways: as a command line, or as a menu driven utility. The first way (command line) is only recommended for testing the program or something else associated to it, because if there is installed any TSR program as the "DOSKEY", the password used will be available to other persons, before the computer is turned off ! >> F.E.D. as a command line utility : Usage : "FED
