Regenerates a chef-client's API key. You want to use this if you believe your client keys could be exposed as a result of the heartbleed vulnerability.

By default, this cookbook will cause chef-client to rekey itself every 24 hours. This can be adjusted with the attribute node['client-rekey']['interval'], which is the maximum allowed age of the client key in seconds.

The library in this cookbook will honor the client configuration setting local_key_generation. If set to true in the client.rb configuration file, the private key will be generated locally and only the public key will travel over the wire. This requires a Chef 11 server.

If you use chef-vault or any other code that uses your client's keys, you'll need to re-encrypt your data each time you rekey.

This is expected to work on all platforms that chef-client supports.

node['client-rekey']['interval']: This recipe uses the mtime of your client.pem to determine when it was last updated. If the difference between now and the file's mtime is greater than this interval setting, your client key will be regenerated.

Include client-rekey in your node's run_list:

{
  "run_list": [
    "recipe[client-rekey::default]"
  ]
}
