SSH WebSocket and OVPN WebSocket differ in their underlying technology and protocols, which they use to establish secure connections. SSH, or Secure Shell, is a cryptographic network protocol designed for securely operating network services over unsecured networks. It is primarily employed for accessing remote systems and executing commands over a secure channel. SSH WebSocket refers to using SSH over a WebSocket connection.

On the other hand, OVPN WebSocket refers to OpenVPN over WebSocket. OpenVPN is an open-source virtual private network (VPN) protocol that creates secure point-to-point or site-to-site connections in routed or bridged configurations. VPNs are typically used to provide secure and encrypted communication between devices over unsecured networks, such as the internet. WebSocket is a protocol that allows full-duplex communication channels over a single, long-lived connection, typically between a client and a server.

By combining SSH or OpenVPN with WebSocket, users can establish secure connections over web-based protocols, enabling them to bypass certain network restrictions, such as firewalls or content filtering systems. While both SSH WebSocket and OVPN WebSocket offer secure communication, they differ in their primary use cases, with SSH being more focused on remote command execution and secure file transfer, while OpenVPN aims to provide a secure and encrypted tunnel for all network traffic between devices.
