This commit adds basic serial link and protocol support. None of the commands
from the docs/design.md document is implemented yet.
The following new packages have been added:
- seriallink containing the serial link handler including COBS decoding and
encoding
- protocol containing the protocol handler including msgpack unmarshalling
and marshaling
- health containing a rudimentary health check implementation
- messages containing command and response types and generated msgpack
marshaling code
A client simulation command has been added in cmd/clientsim.
README.md got instructions how to run the client simulator. The
docs/config.sample.yaml contains a new section for the serial connection
parameters.
This commit implements a mechanism to load CA configuration dynamically from
JSON files. Missing keys and certificates can be generated in a PKCS#11 HSM
or Smartcard. Certificates are stored as PEM encoded .crt files in the
filesystem.
The default PKCS#11 module (softhsm2) is now loaded from a platform specific
path using go:build comments.
- add documentation how to initialize SoftHSM for testing
- add cmd/signer package to hold future signer command
- add test to use a private key from softhsm to create a root
certificate
