Add secure SSH session and file transfer capabilities to any .NET application.
PowerTCP SSH and SFTP for .NET delivers a set of components that allow developers to implement secure remote communication and file transfer capabilities. The library supports encrypted SSH-2 connections, advanced authentication options, and efficient file transfer functionality, enabling applications to securely communicate with remote servers and manage files over SFTP.

SSH Client Session Component

Establish secure SSH-2 connections to remote hosts for executing commands and managing remote sessions. The component supports encrypted communication channels and secure authentication methods for reliable remote access.

SFTP File Transfer Component

Provides a full-featured SFTP client built on SSH-2, enabling secure file uploads, downloads, deletions, and directory management operations between applications and remote servers.

Secure Authentication Methods

Supports multiple authentication mechanisms including password authentication and public key authentication using PEM keys, helping applications securely connect to SSH servers.

Modern Encryption Algorithms

Implements strong SSH-2 encryption algorithms including AES-128, AES-192, AES-256, and Triple DES modes, along with secure HMAC hashing algorithms such as SHA-2 and SHA-1 variants to ensure encrypted and authenticated communication between applications and remote servers.

Efficient File Transfer Handling

Optimizes file transfers with features such as concurrent operations, transfer resumption, and pipelined requests to improve performance when transferring files over SFTP.

Progress and State Monitoring

Provides events such as transfer progress and connection state changes, allowing applications to track file transfer activity and manage connection status during runtime.

Secure Channel Management

Supports the creation and management of encrypted SSH channels that allow applications to securely exchange commands and data with remote systems. The component handles session initialization, encryption negotiation, and channel lifecycle management within the SSH connection.

Directory and File Management Operations

Provides built-in methods for browsing remote directories, retrieving file attributes, creating and removing directories, and managing files directly through the SFTP protocol, enabling applications to fully control remote file systems.
