Data
protection with 256-bit AES-encoding (Rijndael)
With a few mouse-clicks and by entering a password, encode fast and
simple files or complete directories with strong cryptography! Just
click in the WINSWEEP-monitor and select the function <Data
Security> in the WINSWEEP monitor. You then can choose whether you
want to encode individual files or complete directories. If you choose
to encode a directory all sub directories including the files
contained within will also be encoded. We recommend to experiment with
testfiles before encoding of important data!
The
National Institute of Standards and Technology (NIST) of the USA in 1997
has tendered a competition for an advanced encryption standard (AES)
to find a DES-successor (cp. http://csrc.nist.gov/encryption/aes/).
On 10/2/2000 the Rijndael method was declared winner of the competition
and therefore AES. It was developed by the Belgiums Joan Daemen and
Vincent Rijmen. The AES shall replace the aged data encryption standard (DES)
and is anticipated to secure classified data worldwide for the next 20
to 30 years. For the time being, there is no known method that can
break the Rijndael-algorythm. "For a key-size of 128 bit for
example there is the possibility to generate
340,000,000,000,000,000,000,000,000,000,000,000,000. To find exactly
the right one to crack the code,
today’s available super computers
would have to calculate for trillions of years - longer than the
universe already exists." Source: heise.
The WINSWEEP-safe and the secure favourites as well use the AES-encoding. WINSWEEP
prevents that important system directories and folders will be encoded
by mistake. If you have made multiple encodings of files or
directories (by mistake) you have to decode them as many times.
Particular system files such as exe- or dll-files will not be encoded
even if they are within the directory to be encoded.
In any case memorise the allocated password! Without the right password
cannot be decoded again and are lost! Unfortunately requests at the
manufacturer regarding lost passwords are futile. Also we cannot
decode your data without the right password. |
