SFTP, SCP and SSH server component for .NET.
Rebex File Server delivers a comprehensive .NET library for building secure SFTP, SCP, and SSH servers. Perfect for developers needing flexible remote file access and terminal emulation, it offers easy endpoint binding, customizable user authentication, virtual file system integration, and advanced SSH tunneling capabilities.

Easy-to-use API

Provides a straightforward API allowing developers to quickly configure and start SFTP, SCP, and SSH servers with minimal code. Supports launching, binding to ports, managing keys, and user administration.

Server Management

Enables binding SFTP, SCP, and SSH modules to specific IP addresses and ports. Handles server private keys, session lifecycle management, connection control, and server-wide settings to customize behaviors and security.

SFTP Server Support

Implements SFTP protocol over SSH to provide secure remote file system access. Supports virtual filesystems, upload/download tracking, and compatibility with popular SFTP clients like OpenSSH and WinSCP.

SSH Server Capability

Offers a full SSH server supporting subsystems, a virtual shell environment, and custom commands. Allows detailed configuration of SSH ciphers and server parameters compliant with modern SSH standards.

SCP Server Functionality

Includes a simple virtual shell implementing the SCP protocol for secure file copying. Compatible with widely used SCP clients, providing an additional secure file transfer method over SSH.

SSH Tunneling and Port Forwarding

Supports outgoing TCP port forwarding and incoming reverse tunnels via SSH to enable secure proxying and networking scenarios.

Flexible User Authentication

Supports multiple authentication methods including username/password, public key, password and public key, certificate-based, and custom authentication providers. Includes a built-in virtual user database and allows integration with external authentication mechanisms.

Comprehensive Private Key Handling

Allows loading, saving, and converting of various SSH private key formats such as PKCS #8, PuTTY .ppk, and OpenSSH keys. Supports SSH key generation, smart card keys, and certificate-based private keys.

Virtual File Systems

Includes built-in providers for local file systems and in-memory storage with the option to mount multiple directories. Developers can implement custom file system providers for specialized access or composite storage solutions.

Access Control and Event Handling

Provides granular file access controls from unrestricted to read-only or disabled access. Allows event-driven customization for authentication, connection management, command execution, and file transfer activities to monitor and extend server behavior.
