- rework package to allow convert config to model and retrive config from model - add sub package to manage cipher, curves, auth client, tls version, certificates, root ca... - add some small test (can be expande to having more coverage) - optimize some code Package httpcli: - update code following change in certificates Package httpserver: - update code following change in certificates Package Config/Components: - update code following change in certificates Package FTPClient: - update code following change in certificates Package Nats: - update code following change in certificates
