- Introduction:
-
- Welcome to U.C.I. Crypt!! A file encryption/decryption
- utility for the IBM PC/XT/AT/JR, COMPAQ, and all other
- compatibles running under DOS 2.xx and higher. This program
- was written in structured assembly language on an IBM XT.
- Note: Don't rename CRYPT.EXE to anything else for security
- reasons and because the program will ignore CRYPT.EXE when it
- encrypts/decrypts files.
-
- Instructions:
-
- U.C.I. Crypt is a very useful, simple, and relatively
- fast running utility that enables the user to secure ones
- files from unauthorized viewing, execution, and possible
- modifications. The program scrambles the selected file to
- the point where it is completely unexecutable and unviewable.
- To begin this process type at the DOS prompt A>Crypt and the
- program should come up with a startup up screen and ask you
- for a directory mask. The program defaults to *.* or you may
- enter your own specifications. ALL DOS WILDCARD CHARACTERS
- ARE ACCEPTABLE and subdirectories are also supported. Next
- the the program will ask you if you want to encrypt or
- decrypt files. SPECIAL NOTE: You may only encrypt a file
- once to prevent other unauthorized users from trying to
- encrypt a file without your knowledge. Next the program
- prompts you to enter either an encryption or decryption
- string. This string can be from 1 to 80 characters and must
- be remembered in order to decrypt the file. WARNING!! YOU
- MUST REMEMBER YOUR ENCRYPTION STRING!! Next you will be
- prompted whether or not you want to manually select each
- file. Now you are through with your work and now its up all
- to the computer. Good Luck and don't forgot your encryption
- string!

-
- Reserved Filenames and Error Messages:
-
- Certain filenames such as AUTOEXEC.BAT, COMMAND.COM,
- CONFIG.SYS, CRYPT.EXE, and others have been specially flagged
- so they won't be encrypted for user convenience. An
- insufficient space available error message is displayed when
- you attempt to encrypt a file that requires more space than
- is currently available on your disk. Most other error
- message are self-explanatory and currently do not need to be
- explained.
