Most VOLTTRON users should not need to directly interact with agent key stores. These are notes for VOLTTRON platform developers. This is not a stable interface and the implementation details are subject to change.
Each agent has its own encryption key-pair that is used to authenticate itself with the
VOLTTRON platform. A key-pair comprises a public key and a private (secret) key. These keys are saved in a
“key store”, which is implemented by the
KeyStore class. Each agent
has its own key store.
Key Store Locations
There are two main locations key stores will be saved. Installed agents’ key stores are in the the agent’s data directory:
Agents that are not installed, such as platform services and stand-alone agents, store their key stores here:
Generating a Key Store
Agents automatically retrieve keys from their key store unless both the
secretkey parameters are
specified when the agent is initialized. If an agent’s key store does not exist it will automatically be generated upon
Users can generate a key pair by running the following command:
vctl auth keypair
