A:There are no “backdoors” into X-Wall LX secure systems, so without the X-Wall Secure Key you will not be able to access the data or operating system on the protected disk. This means you must keep the backup key in a safe place at all times.
Q:If the X-Wall LX malfunctions, will I lose my data?
A:No. Remember that the X-Wall Secure Key contains the DES/TDES secret key; the X-Wall LX chip is a generic engine. Consequently, you can simply replace the defective X-Wall LX component, if that ever occurs, and use your original X-Wall Secure Key to access the data on your hard drive.
Q:What’s the likelihood an X-Wall LX malfunctions?
A:Every X-Wall LX family microchip we ship is 100% tested and proven and complies with International quality assurance standards1. However, there may be occasions that chip malfunctions after some period of time. This problem can be resolved by simply replacing the defective X-Wall LX microchip. The contents of the disk drive will NOT be lost as long as you retain the original X-Wall Secure Key intact. Nevertheless, disk failures can occur, so it is good practice to always keep a backup of your important data, for which we do have a good solution on the back up device: Secure USB2.0. Please refer to our website for more details. In case of system failure, please double-check with your disk drive prior to reporting any malfunction of the X-Wall.
Q:Can I exchange the X-Wall LX encrypted files using the public
network?
A:No. The X-Wallsystem was specifically designed to protect data “at rest” (stored) on your PC. The DES/TDES encryption engine built inside the X-Wall LX is a symmetric cipher, a “Secret Key” system that does NOT support the Public Key Infrastructure (PKI). Therefore, you will not be able to exchange X-Wall LX encrypted files through public network, as every file leaving X-Wall interface is the clear text.
Q:Does X-Wall LX increase the original file size after encryption?
A:No. DES/TDES is a complicated mathematical algorithm that computes the original data with 40-bit key length. Regardless of the size of the encryption key, the size of data file after encryption remains unchanged.
