      <title>Description</title>
      <para>The <command>slogkey</command> utility is used to manage cryptographic keys for use with the secure logging module of <command>syslog-ng</command>. Use this utility to create a master key, derive a host key to be used by a secure logging configuration and to display the current sequence counter of a key. The options determine the operating mode and are mutually exclusive.</para>

	    <para>&lt;host MAC address&gt;: The MAC address of the host on which the key will be used. Instead of the MAC address, any other string that uniquely identifies a host can be supplied, e.g. the company inventory number.</para>
	    <para>&lt;host serial number&gt;: The serial number of the host on which the key will be used. Instead of the serial number, any other string that uniquely identifies a host can be supplied, e.g. the company inventory number.</para>
	    <para>&lt;host key file&gt;: The name of the file to which the host key will be written.</para>
        <para>NOTE: The newly created host key has its counter set to 0 indicating that it represents the initial host key k0. This host key must be kept secret and not be disclosed to third parties. It will be required to successfully decrypt
        and verify log archives processed by the secure logging environment. As each log entry will be encrypted with its
        own key, a new host key will be created after successful processing of a log entry and will replace the previous key. Therefore, the initial host key needs to be stored in a safe place before starting the secure logging environment, as it will be deleted from the log host after processing of the first log entry.</para>
