NAME
       slogencrypt  ---	 Encrypts  existing  plain text	log files using	the {{
       site.product.short_name }} secure logging environment.

Synopsis
	      slogencrypt [options] [arguments]

Description
       The slogencrypt utility encrypts	plain text log files using an existing
       secure logging environment. Using this utility, log files obtained from
       a previous installation of syslog-ng OSE	or another logging system  can
       be  transferred	to  a secure logging environment. The order of the log
       entries is preserved. Encrypting	plain text log files using an existing
       secure logging environment, requires the	current	encryption key	to  be
       supplied	in order to preserve consistency.

   Example: a general call sequence
	      slogencrypt -k <key file>	-m <MAC	file> <new key file> <new MAC file> <plain text	log> <output file> [counter]

Arguments
	      •	<new key file>

	      The  file	 that containa the new encryption key after successful
	      encryption.

	      •	<new MAC file>

	      The file receiving the new message authentication	code (MAC)  of
	      the  secure  encrypted  destination after	encryption. In case an
	      existing file is supplied, new entries are appended.

	      •	<input log file>

	      The plain	text log file that is encrypted	using the secure  log-
	      ging environment.

	      •	<output	log file>

	      The  file	 that contains the encrypted log entries from the sup-
	      plied plain text log file	after encryption.

	      •	counter

	      The current log entry counter of the secure  encrypted  destina-
	      tion after encryption. This is required if the log entries to be
	      encrypted	 are appended to an existing secure encrypted destina-
	      tion

Options
	      •	--key-file or -k

	      The current host key from	the system  where  the	encryption  is
	      performed.

	      •	--mac-file or -m

	      The  current  MAC	 file  from the	system where the encryption is
	      performed.

	      •	--help or -h
