Health Net Secure (HNS) is designed to provide a secure method for accessing the Ministry of Health's HL7v2 messaging services. It consists of 2 major components, a client and an ESB server.
The HNS-Client is an optional component, it replaces the old HNClient and is intended to be a stop-gap solution for transitioning existing client applications to the new HNS-ESB without any modification to the client application. HNS-Client runs in the background on a clients server, and will allow client applications to send messages to it via the same connection protocol as the old HNClient (HL7XFER). The modern client incorporates a number of improvements including modern encryption protocols, and improves on a number of “pain points” experienced by current users of the HNClient such as encryption key management.
The HNS-ESB exposes Ministry of Health HL7v2 services via an API Gateway. It is used to audit, and securely route any type of HL7v2 messages to their appropriate message service provider, such as RAPID or Pharmanet. This application acts as a single point of access for the HNClient-v2 application and it is not backwards compatible with the old HNClient.
The application performs an authorization check against the JWT that must be passed in the Authorization header and also does light message validation before routing the message to a final destination.
