A reliable and efficient implementation of the SSH File Transfer Protocol (SFTP).
Xceed SFTP for .NET is a fully managed component that facilitates secure file access, transfer, and management over SSH connections in .NET environments. It supports essential SFTP protocol versions and provides features such as encrypted data transmissions, file and folder manipulation, proxy compatibility, and filter-based file transfers, making it a versatile solution for developers working with secure file transfers.

SFTP Protocol Implementation

Implements SSH-2 protocols according to RFC standards, supporting SFTP protocol. It establishes encrypted and integrity-checked data exchanges with automatic key rotation to maintain secure communication channels.

File and Folder Abstractions

Exposes remote files and folders as SFtpFile and SFtpFolder objects integrating smoothly with Xceed’s FileSystem component.

File Transfer Operations

Enables secure uploading and downloading of individual files, multiple files, or entire directory structures to and from disk or memory streams, with options to rename destination files or folders during transfer.

Filtering and Synchronization

Supports flexible synchronization and transfer filtering based on name, date, attributes, and size, allowing selective file operations tailored to specific criteria, including the use of wildcards.

Proxy Support

Connects to SFTP servers through HTTP and SOCKS 4/4A/5 proxies, facilitating operation within varied network environments by delegating connection responsibilities to proxy servers when required.

Event-Driven Error Handling

Offers configurable event handling during multi-file transfers to retry, skip, or abort operations if errors occur, enabling controlled and responsive transfer management in applications.

Session and Connection Management

Allows multiple SFTP sessions multiplexed over a single SSH connection for efficient use of network channels. Both SSHClient and SFtpSession implement IDisposable to facilitate resource management via .NET’s using block patterns.

Logging and Timeout Controls

Provides options to log SFTP activity to various outputs and can enforce timeouts on all operations. It also raises events if server connections are lost, helping developers monitor and control transfers robustly.
