Adds a new key to the key ring. valid-after uses the format:
to indicate a time relative to the current time. The units for the time are specified by appending a single letter. That letter can be any of s, m, h, d, or w, which correspond to seconds, minutes, hours, days, and weeks respectively.
For example: 10d is 10 days from the current time, and -60d is 60 days before the current time.
Garbage collects (removes) old keys on the key ring. Any keys with a
valid-after date older then the specified time will be removed from the
The format for oldest-valid-after-to-keep is the same as valid-after from the add command. Note that this means that times given to the gc command should generally be negative, to remove keys that have expired in the past.
Lists all the keys in the key ring. By default, a brief listing is
used, but a verbose listing can be requested with the -v option.
The following fields are present in a short listing:
The following fields are present in the long listing:
|remove id||Remove the key with ID id from the key ring.|
Ownership (user and group) of the existing keyring file will be preserved if possible without overwriting the existing file. Permissions will also be preserved, with the exception that permissions will not be copied to the new file if the old file was group-readable or group-writable and setting the group ownership failed.
Add a key to the keyring valid as of the current time:
wa_keyring -f keyring add 0d
Add a key to the keyring that will be valid three days from now:
wa_keyring -f keyring add 3d
Remove keys from the key ring that became invalid more than 90 days ago:
wa_keyring -f keyring gc -90d
Remove the first key in the keyring.
wa_keyring -f keyring remove 0
Display a verbose listing of all of the keys in the key ring:
wa_keyring -f keyring -v list
Note that a WebAuth server will normally manage its keyring file by itself, and wa_keyring is normally only used for debugging purposes. However, if you are setting up a load-balanced pool of servers that need to all share the same keys, turn off automatic keyring handling by putting the line:
to your Apache configuration, running a script periodically from cron on one server that does something like:
wa_keyring -f keyring gc -90d wa_keyring -f keyring add 2d
and then copying (in a secure manner!) the new keyring file to all of the other servers.
