The Dual CipherChain uses a fast cryptology engine, the ENOVA® X-Wall MX-256, which is NIST & CES certified. This engine uses AES encryption to encrypt entire drives. Simply said. AES uses mathematical formulas and algorithms to come to, in this case, a 256-bit key. To explain in detail how AES or encryption works is outside of the scope of this article.
The CipherChain uses keys, a little hardware key with a male mini USB connector, and the circuit board has a female USB connector on it. This is the KEY. The only thing you have to do is stick this key in the CipherChain, connect the circuit board to the computer using SATA, connect the hard drive, and turn everything on. BACK UP OUR DATA on the drive you are going to use. The CipherChain will now delete all the data on the hard drive and encrypt it. Now you are ready to re-create the partition table (yes it really destroyed all the data), create the first partition, and load the data back on the drive.
One of the key features of the CipherChain is that the engine is fast. I didn't notice any speed decrease in data transfers; the speeds measured are what you would expect of an external USB hard drive. (Speeds were measured with ATTO Disk Benchmark.)
