Secure FTP Library for .NET Framework

Don't want to send clear-text password over the network?

Use Secure FTP component to encrypt your FTP session.

Secure FTP for .NET is a versatile file-transfer component for .NET languages (such as C# or VB.NET). It allows you to transfer files directly from your application using FTPS, an extension of FTP which is fast becoming a standard for secure FTP. This protocol is also known as FTP over SSL or FTP over TLS and is defined by RFC 4217.
Secure your FTP transfers using TLS and SSL protocol

FTPS enhances the standard FTP protocol by utilizing the well known and widely used TLS and SSL protocol. TLS 1.0 and its predecessor SSL 3.0 provide strong authentication, integrity and confidentiality on both the control and data channels. This is achieved by using RSA or DSA public key cryptography to authenticate the server (or even the client) and to negotiate the encryption method and symmetric keys to be used to encrypt your data. There are many FTP servers that support FTPS and their number is growing constantly.
Upload from memory, resume aborted transfers & more...

- either synchronously or asynchronously, in active or passive mode, binary or ASCII. Upload data directly to your server without creating temporary disk files. Resume transfers that were aborted by a network error or user action. Open a remote file as a stream and work with it as if it was accessible locally. Monitor upload and download status and progress using custom events. Send raw FTP commands to utilize enhanced functionality.
