Note: 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 to 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
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
secretkey parameters are specified
when the agent is initialized. If an agent’s key store does not exist
it will automatically be generated upon access.
Users can generate a key pair by running the
volttron-ctl auth keypair command.
