NAME

       ekey-rekey - Entropy Key Long Term Session Key tool

SYNOPSIS

       ekey-rekey [ -d DeviceNode ] [SerialNumber [MasterKey]]

DESCRIPTION

       ekey-rekey  is  a tool which sets the long-term key of an Entropy Key using its Master Key. It ensures any running ekey daemons are updated
       with the altered keys.

OPTIONS

       SerialNumber
	      Specifies the serial number of the key to re-key.  If this is not specified, the identity of the	Entropy  Key  currently  connected
	      will be automatically detected.

       MasterKey
	      Specifies the Master Key of the device being re-keyed.  If this is not specified, the user will be prompted for it.

       DeviceNode
	      If  -d or --device is specified, then the tool expects to be give the device node to use (such as /dev/ttyACM0) rather than attempt-
	      ing to work it out from the serial number provided.
