Currently server's keystore is in a file named keystore
Core services such as config.store have keys defined in vhome/keystores/<vip_identity>/keystore.json
Installed agents keys get saved in vhome/agents/keystore.json

There are currently no DEV dependencies, so far I recommend:

-pytest
-mock

I am sure more to come as I work my way through getting the tests to run.

It looks like the code is designed to run on Windows (which won't have syslog), but the reliable import attempt does not work because there is another syslog import statement above it.

ClientContext should be the go to class for agents to get information related to environment - server, vhome, keystore etc. AIP should not call clientcontext. AIP should set env variables and ClientContext should read it from the environment

add ability to get

AGENT_SECRETKEY
AGENT_PUBLICKEY
VOLTTRON_SERVERKEY

you could then run the agent from command line

AGENT_SECRETKEY=<secretkey> AGENT_PUBLICKEY=<publickey> VOLTTRON_SERVERKEY=<serverkey> python agent.py

cryptography version 2.3 has the following Python versioning requirement:

cryptography==2.3 -> python[version='>=2.7,<2.8.0a0|>=3.5,<3.6.0a0|>=3.7,<3.8.0a0|>=3.6,<3.7.0a0']

Which is not compatible with Python >=3.8.

For some reason this is only printed out when you don't redirect to a log file.
