Enable Encryption

Rijndael is the block cipher algorithm chosen by the National Institute of Science and Technology (NIST) as the Advanced Encryption Standard (AES) to be used by the US government. The xDirect supports 128-, 192-, and 256-bit encryption key lengths.

Note: Configuring encryption should be done through a local connection to the serial port of the xDirect, or via a secured network connection. Initial configuration information, including the encryption key, is sent in clear text over the network.

To configure AES encryption on the xDirect:

Enable Encryption (N) Y

Key length in bits (0): 128
