Intro:
We all use ZIP files (compressed files) for saving disk space. PKZIP is one of the famous
ZIP utility. PKZIP provides us security mechanism to save the contents of ZIP file being viewed
by others. For this security mechanism one has to use passwords. These passwords can be
cracked with dictionary attacks. The encryption algorithm uses case sensitive passwords.
The very famous Windows based WinZip also uses the same compression algorithm used
by PKZIP. So there is no difference between the ZIP file created with WinZip and PKZIP.
