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.
