Features

• SSH Client Connections - Implements the core SSH2 protocol for establishing authenticated connections between Node.js clients and remote servers.
• SSH Protocol Implementations - Provides a pure-JavaScript implementation of the SSH2 protocol, eliminating dependencies on native C libraries.
• SCP and SFTP Subsystem Handlers - Implements an SSH server capable of handling SFTP protocol requests for remote file management.
• SFTP Client Libraries - Provides a full client library for managing remote file systems and transferring data via the SFTP protocol.
• Remote Command Execution - Enables running specific shell commands on remote servers and capturing their standard output and error streams.
• Programmatic Remote Execution - Enables Node.js applications to execute remote commands and manage server sessions programmatically.
• Connection Multiplexing - Enables multiple independent logical streams for shell, SFTP, and port forwarding over a single encrypted connection.
• SFTP File Transfers - Provides a comprehensive SFTP client for reading, writing, and managing remote files via the SSH protocol.
• SSH2 Protocol Libraries - Provides a comprehensive JavaScript implementation of the SSH2 protocol for both clients and servers.
• Asymmetric Key Management - Provides utilities for the creation and serialization of asymmetric keys such as RSA and ED25519 for SSH authentication.
• Handshake Key Negotiations - Coordinates version exchange and key negotiation to establish secure symmetric keys during the connection handshake.
• SSH and Telnet Server Implementations - Includes a full server-side implementation of the SSHv2 protocol for hosting secure remote access services.
• SSH Key Management - Includes tools for generating, parsing, and verifying cryptographic keys used for secure SSH identity authentication.
• User Authentication Systems - Implements identity verification using passwords, public keys, and interactive prompts for secure access.
• Packet Framing Protocols - Implements length-prefixed packet framing to synchronize encrypted data streams over TCP.
• Binary Packet Parsing - Implements low-level binary parsing using buffers to handle the SSH protocol's packet structures.
• Batch Command Executions - Allows for the execution of a series of commands on a remote server and capture of their resulting output.
• HTTP Tunnels - Supports routing HTTP and HTTPS requests through encrypted SSH tunnels for secure network communication.
• Local Port Forwarding - Provides local port forwarding to route network traffic from a local port to a remote destination via SSH.
• Reverse SOCKS5 Proxy Tunnels - Implements a SOCKSv5 proxy that routes general network traffic through an encrypted SSH tunnel.
• SSH Tunneling Forwarders - Wraps TCP socket traffic inside SSH channels to route network data through an encrypted proxy.
• Multi-hop Forwarding - Supports establishing a sequence of forwarded connections to reach servers that are not directly accessible.
• Encrypted Tunneling - Routes TCP, HTTP, and SOCKSv5 traffic through secure SSH tunnels to bypass firewalls.
• Key Pair Generations - Provides utilities to generate public and private key pairs using various cryptographic algorithms.
• SSH Key Parsers - Includes utilities to parse SSH keys from standard formats for signing and verification processes.
• Interactive Remote Shells - Supports opening and managing pseudo-TTY sessions for real-time interaction with remote servers.
• General Utilities - SSH2 client and server module.
• SSH Libraries - Pure JavaScript SSH2 client and server modules for Node.js.
