               X2TEK PERSONAL DATA SECURITY PROGRAMS

     These programs are for securing personal data files with passwords.   The password can be of almost any length so sentences are OK.   Each character in the file is encrypted using encryption keys  which depend on the password, root filename, and character position in the file.  After  each usage,  the encryption key is modified with a random number.  This encryption cycle can now be repeated up to 99 times by using the last encrypted file as the source file to repeat the process.
