TANGD-ROTATE-KEYS(1)					  TANGD-ROTATE-KEYS(1)

NAME
       tangd-rotate-keys - Perform rotation of tang keys

SYNOPSIS
       tangd-rotate-keys [-h] [-v] -d <KEYDIR>

DESCRIPTION
       in order	to preserve the	security of the	system over the	long run, you
       need to periodically rotate your	keys. The precise interval at which
       you should rotate depends upon your application,	key sizes and
       institutional policy. For some common recommendations, see:
       https://www.keylength.com.

       tangd-rotate-keys generates new keys in the key database	directory
       given by	the -d option. This is typically /var/db/tang. It also rename
       the old keys to have a leading .	in order to hide them from
       advertisement.

       Tang will immediately pick up all changes. No restart is	required.

       At this point, new client bindings will pick up the new keys and	old
       clients can continue to utilize the old keys. Once you are sure that
       all the old clients have	been migrated to use the new keys, you can
       remove the old keys. Be aware that removing the old keys	while clients
       are still using them can	result in data loss. You have been warned.

OPTIONS
          -d <KEYDIR>:	The directory with the keys, e.g. /var/db/tang

          -h: Display the usage information

          -v: Verbose.	Display	additional info	on keys	created/rotated
