# Chef Client Release Notes : ## Knife Key Management Commands for Users and Clients `knife user` and `knife client` now have a suite of subcommands that live under the `key` subcommand. These subcommands allow you to list, show, create, delete and edit keys for a given user or client. They can be used to implement key rotation with multiple expiring keys for a single actor or just for basic key management. See `knife user key` and `knife client key` for a full list of subcommands and their usage.
