WireGuard's Dual Role: VPN Application and Lightweight Cryptographic Protocol
By
mlhpdx
Hot, fresh, and worth queueing round the block for.
Summary
The article explains that WireGuard serves two distinct purposes: as a VPN application and as a lightweight cryptographic protocol. While most developers know WireGuard as a VPN tool, it can also function as a stateless encryption layer for any UDP application without requiring a full VPN setup. The article explores both use cases, highlighting WireGuard's simplicity, performance advantages, and how developers can leverage it beyond traditional VPN applications.
