Secure, Robust, Reliable
All communications between
CrafTech DataBank's Backup
Servers and your computer are
transported in a 128-bit SSL
(Secure Socket Layer) channel.
Although all your backup files
travel through a public network
(internet), eavesdroppers have
no knowledge of what has been
exchanged.
Backups are securely encrypted
All of your files are first
zipped and encrypted with your
defined encryption key before
they are sent to CrafTech
DataBank's backup servers. To
everyone but you, your data
stored on CrafTech DataBank's
backup servers are no more than
unreadable garbage files with
random content.
We don't keep your encryption
key
The encryption key used to
encrypt your files resides only
on your computer and is known
only to you. It is never
transmitted anywhere across the
network. If this key is lost,
all backup files can never be
recovered. Therefore, although
we have access to all files you
have stored on our backup
server, we have no knowledge or
access to the content of the
files stored.Reminder : Please
make sure you write down you
encryption key and keep it in a
safe place where it will never
be forgotten. Otherwise, you
will never be able to recover
your backup files.
Best encryption algorithm is
used
Currently, the algorithm that
we are using to encrypt your
files is 128-bit Twofish. It is
a block cipher designed by
Counterpane Labs. It was also
one of the five Advanced
Encryption Standard (AES)
finalists chosen by National
Institute of Standard and
Technology (NIST). It is subject
to frequent public reviews but
no known attack against this
algorithm has ever been
reported.
Requires 8.77 x 1017 years to
crack 128-bit encryption
A 128-bit key size has 2128
or around 3.4 x 1038 possible
combinations. Even if you have
the world's best super computer,
ASCI White, SP Power3 375 MHz
manufactured by IBM as of
November 2000, it would take
8.77 x 1017years to test all
combinations.Assuming your have
the super computer, ASCI White,
SP Power3 375 MHz has 8192
processors which totals a
capability of 12.3 teraflops
(trillions of
operations/second), available to
you. Also, it just needs one
computer operation to test a
possible combination (which is
already faster than what it can
do). To use brute force attack
(checking all combinations) on
this encryption algorithm. It
would take:
3.4 x 1038
-------------- seconds ~ 2.76 x
1025sec
12.3 x 1012
i.e. 876530835323573935 years
or 8.77 x 1017 years
to successfully try all
combinations. Let alone ASCI
White cannot process as fast as
what is described here. You can
be sure that your data stored on
our servers is 100% secured.
Restrict access to data by IP
addresses
You can also restrict access
to your backup files from the
set of IP addresses you define.
If someone tries to access your
data from an IP address not on
your defined list, their access
will be denied. This additional
security ensures backup files
are not open to all locations,
even when username and password
are known.
