SFTP and SCP client .NET library.
Rebex SFTP offers a .NET library for secure file transfers over SSH using SFTP and SCP protocols. It integrates authentication with varied mechanisms and delivers APIs to handle files, directories, and transfer operations. The component supports advanced protocols and security standards, enabling developers to build reliable and flexible remote file management solutions.

Authentication

Authenticate using username/password, public/private keys, X.509 certificates, GSSAPI, NTLM, Kerberos, single sign-on, and keyboard-interactive methods.

File Operations

Upload, download, rename, delete, and manage file attributes with support for atomic moves, partial transfers, checksums, and symbolic link handling.

Directory Management

Perform directory listings, recursive directory operations, creation, deletion, renaming, and existence checks with LINQ support and symlink awareness.

Robust Transfer Features

Support for resumable transfers, transfer speed limiting, progress events, auto-renaming, ASCII and binary modes, and transfer compression.

SSH Core Integration

Includes features like running remote commands, SSH session sharing, keep-alive packets, key re-exchange, and tunneling through SSH with updated cipher support.

Asynchronous and Event-driven API

Fully supports asynchronous programming patterns including Task-based async, await operator, IAsyncResult, and events for transfer progress and authentication.

Stream-Based File Access

Access remote files using .NET streams for read, write, or read/write operations, enabling processing files as if stored locally.

Security and Private Key Handling

Provides server verification, fingerprint checks, FIPS mode compliance, and supports key formats like PKCS#8, PuTTY, OpenSSH, and smart card usage.
