Do you want the best in security, reliability, and performance for SSH? Buy the .NET SFTP Library from Kellerman Software. The component supports public key authentication and private key authentication using passphrases. OpenSSH, Putty, and IETF formats can be used. Proxy servers are also supported. The .NET SFTP Library excels at handling intermittent network connections. The .NET SFTP Library is the only component available where you can unplug the cable in the middle of a transfer, plug it back in, and it resumes automatically where it left off. The .NET SFTP Library is the only one that can calculate the time difference between two servers to perform an ultra fast directory tree synchronization. Competitor libraries use the file size, which could actually miss updated files with the same size. It supports all .NET project types including ASP.NET MVC, WPF, Webforms, Winforms, WCF, Windows Services, and Web Services. It can be used with any .NET language including VB.NET and C#. Why pay more for another SFTP library that is less reliable and has less features? Download the full list of features.

We also have a library to perform FTP over SSL. An FTP Adapter is included that allows you to use both components from the same interface. Use the discount code FTPANDSFTP to get a discount when purchasing both.
