Associates a DES(default) or AES algorithm Message Authenticate
    Code (MAC) value with one or more files and checks for any
    modification of either plain text or cipher text files. Use the
    additional /UPDATE qualifier to store each file's MAC in the
    databases. Use only the /AUTHENTICATE qualifier to subsequently
    test the integrity of the file's data and security attributes.
    You must create a DES or AES key prior to updating or checking an
    existing MAC. When using the AES algorithm, you must specify the
    /AES qualifier. You can use AES algorithm only with respective AES
    key and the DES algorithm only with DES key. For more information
    about creating DES or AES key and the minimum key length required
    for different algorithms, see ENCRYPT /CREATE_KEY help.
