SFTP File Transfer Library for .NET

Aimed C# and VB.NET developers, SFTP File Transfer Library for .NET is a component that can be integrated into your software applications to provide SFTP capabilities to end users, allowing them to remotely access files through an SSH channel via SFTP. With the help of this tool, it's possible to put together SFTP servers which can be accessed from any supported client (SFTP, SCP, SSH).

The utility offers support for SSH v2, SFTP v3 and v4 servers, IPv6 and IPv4 protocols, and UTF-8 encoding mode. It's also compatible with FIPS 140-2 and it auto-detects symlinks. During transfers, it can compress files to obtain optimum size as well as to speed up downloads and uploads. Once the transfers are over, the tool can be asked to verify checksums to make sure that files were correctly downloaded/uploaded (in case of interruptions). Speaking of interruptions, the .NET library is capable of resuming file transfer on such events.

It gives end users the possibility to perform uploads and downloads on either the memory or disk. Filters can be applied with simple masks or regex. It's possible to delete multiple files and folders at the same time, set restrictions on the transfer speed, and perform certain operations recursively (e.g. delete, upload).

According to the developer, SFTP File Transfer Library for .NET was tested with FileZilla, Windows CE FTP Server and other FTP servers, turning out to be fully compatible. It doesn't use open-source code and has 100% managed C# code. The list of supported platforms includes .NET Framework 2.0 and newer, .NET Compact Framework 3.5 and newer, Mono 3.x and 4.x (for Linux and macOS), XamarinIOS 8.6 and newer, along with XamarinAndroid 4 and newer. Redistribution is royalty-free.
