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
