-
- This program encrypts ANY disk file into garbage. The algorithm is
- EXTREMELY secure and that it would take someone a long time on a fast
- mainframe computer to decrypt your file, and even then might not get it
- if they didn't have the original file to work from.
-
- The program will securely encrypt DOS files of any type, including .COM,
- .EXE, any ASCII file, BASIC files, etc.
-
- The program is a compiled Clipper program. Simply type 'ED-FILE' from
- the DOS prompt. The system will then ask the following questions:
-
- 1. Encrypt or decrypt a file.
- 2. Name of file to be encrypt/decrypt.
- 3. Name of the output file. Enter a different file name then the
- file being encrypted/decrypted if you want to keep the original
- file unchanged.
-
- NOTE: It is good practice to keep a backup copy of the original
- file incase the encryption/decryption key is forgotten.
-
- 4. Encryption/decryption key.
-
-
- You can encrypt an encrypted file as many times as you want and, as long
- as you decrypt it correctly, ie., in EXACTLY the reverse fashion, the
- last encryption first, etc. and with EXACTLY the correct key for each
- level, you'll get your file back.

- Registered users will receive source code and free technical support.
- Registration fee is $10.00. Source code can be easily linked into
- current Clipper 87/50 applications. Procedure to encrypt/decrypt a
- string is included.
