dsh-wan-peers: Cross-Internet DSH Node Discovery and Encrypted Peer-to-Peer Messages

This article introduces dsh-wan-peers, a DSH networking plugin maintained by Myco-Lee. It utilizes ntfy-compatible pub/sub for cross-network node discovery and employs AES-256-GCM for end-to-end encrypted communication. The article details the differences from dsh-lan-peers, the two configuration methods (pairing codes and manual configuration), official installation commands, Agent tools (such as wan_pair, wan_peers, wan_send), as well as the public ntfy.sh quota and security boundaries. It is suitable for developers who need to enable communication between multiple Harness instances in scenarios without public IP addresses.
