This make the encrypted pubsub node fully accessible to +the recipient. + +By default, all node secrets are shared with the recipients, this is normally the desired +behaviour as you most of time want the recipient to have full access to the node. However, +it may be possible to share only some keys by using ``-k ID, --key ID`` argument. + +example +------- + +Louise want to give access to her private blog to pierre:: + + $ li pubsub share secret -n private_blog pierre@example.net + +revoke +====== + +Mark a shared secret as revoked, which means that no new items must be create using this +secret. The secret is still available to decrypt older items. + +By default, the revocation notification is sent to all people known to have the latest +shared secret, this is the recommended way to use this command. However, you may send the +revocation notification only to some entities by using ``-r JID, --recipient JID`` as many +times as necessary. + +It is usually better to use the rotate command below, which automatically revoke all +existing keys and create a new one, sending suitable notifications. + +example +------- + +Louise wants to revoke a shared secret used in her private blog:: + + $ li pubsub secret revoke -n private_blog k4XBRW9rkYQeGN5fiqoK4R + +rotate +====== + +Revoke all shared secrets of a node, and create a new one. Suitable revocation and secret +sharing notifications are sent. + +By default, notifications are sent to all people known to have the latest shared secret. +This is generally what is desirable, unless one or more people who previously had access +to should now be excluded from access to the new items. In this case, you may use the ``-r +JID, --recipient JID`` argument as many times as necessary to specify who should receive +the notifications and new secret. + +example +------- + +Louise wants to rotate shared secrets of her private blog:: + + $ li pubsub secret rotate -n private_blog + +list +==== + +List all known shared secrets of a node. + +By default, the private key is not returned, to prevent it from being accidentally +displayed on the screen. If you want to see them too, increase the verbosity with the +``--verbose, -v`` argument. + +example +------- + +Louise wants to see all secrets used in her private blog:: + + $ li pubsub secret list -n private_blog
