What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over) -What Does the code DO?
