Features

• WebSocket Clients - Ships a terminal-based client for establishing and managing bidirectional WebSocket connections.
• WebSocket Security - Establishes secure, encrypted WebSocket connections using TLS or static symmetric keys.
• Command Piping - Pipes the standard input and output of external command-line programs directly to a network connection.
• Bidirectional Protocol Bridging - Forwards data bidirectionally between different socket types, bridging diverse network endpoints.
• Pluggable Transport Layers - Utilizes a pluggable transport layer to seamlessly relay data between TCP, UNIX sockets, and WebSockets.
• Websocket Connection Managers - Establishes secure or insecure connections to remote WebSocket servers.
• Port-Based WebSocket Listeners - Hosts WebSocket servers listening on TCP ports, UNIX sockets, or abstract-namespaced sockets.
• Secure - Provides a command-line listener that accepts secure WebSocket connections using PKCS#12 certificates.
• Secure Server Implementations - Provides a command-line utility to host secure WebSocket servers using PKCS#12 certificates.
• Event-Driven Networking - Implements a high-performance event-driven networking model using non-blocking I/O for concurrent connections.
• Process-to-WebSocket Wrappers - Pipes an external program's standard input and output streams directly to a WebSocket connection.
• Bidirectional Stream Proxying - Provides bidirectional data stream proxying between remote listeners and local clients.
• Standard IO WebSocket Bridges - Bridges the standard input and output of local processes to WebSocket connections.
• TCP and Unix Socket Listeners - Connects to and listens on TCP and UNIX sockets for raw bidirectional data exchange.
• WebSocket Terminal Clients - Provides a terminal-based interface to connect to WebSocket servers for testing and automation.
• Transport Mapping - Proxies data by mapping TCP connections to WebSocket connections and vice versa.
• File and Console I/O - Facilitates interaction with the console by reading and writing to standard system input and output streams.
• WebSocket Protocol Relays - Bridges and routes data bidirectionally between WebSocket connections, TCP sockets, and UNIX sockets.
• Streaming Data Transformers - Provides a transformation pipeline to modify data streams by adding timestamps or converting messages to lines.
• Broadcast Messaging Channels - Duplicates replies from a single inner connection to all currently connected downstream clients.
• Automatic Reconnection - Automatically re-establishes underlying connections after encountering errors or end-of-file signals.
• Direct-to-Network File Streaming - Streams data from local files directly to network connections or logs traffic to disk using append operations.
• SOCKS5 Proxies - Routes WebSocket connections through SOCKS5 or HTTP proxies to bypass network restrictions.
• SOCKS5 Proxy Tunneling Clients - Acts as a networking client that tunnels WebSocket traffic through SOCKS5 or HTTP proxies to bypass restrictions.
• Text and Binary Message Exchanges - Supports bidirectional transmission and conversion between binary bytes and UTF-8 encoded text messages.
• Proxy-Routed - Routes WebSocket connections through HTTP or SOCKS5 proxies using the CONNECT method to bypass network restrictions.
• Stream Processors - Filters and transforms WebSocket data streams into line-based or binary records for external tools.
• WebSocket Utilities - Includes tools for inspecting raw traffic and protocol frames to debug WebSocket communication issues.
• Line-Based Record Processing - Translates WebSocket messages into line-based records for compatibility with shell-based text processing tools.
• TLS Session Wrapping - Wraps raw socket connections with TLS using PKCS#12 certificates for secure communication.
• Message Encryption - Implements message-level encryption using the ChaCha20-Poly1305 algorithm for secure data transmission.
• Symmetric Encryption - Secures raw byte streams using symmetric encryption with the ChaCha20-Poly1305 algorithm.
• TLS Traffic Encryption - Provides capabilities to wrap connections in TLS encryption or accept secure connections via certificates.
• Network Analysis and Simulation - CLI client for WebSocket debugging and interaction.
• Network Analysis Tools - CLI client for interacting with WebSocket servers.
• Networking Tools - Command-line client for WebSockets with advanced relay functions.
