SFTP client library for C# and VB.NET developers. Provides secure remote file system access over an SSH channel using the SFTP protocol. Makes it easy to transfer files between your application and Unix/Windows SSH servers.

Connect, log on, download a file, disconnect. Upload all text files in a folder at once. It's easy to start developing with our library. Simple code for simple use cases.

Basic username/password authentication is often not good enough. That's why we support additional authentication methods such as keyboard-interactive, public/private key or X509 certificate authentication, NTLM or Kerberos (with single sign-on as well).

Upload a file from the filesystem or memory. Rename and move files. Check existing files. Or perform other single file SFTP operations.

Or simply transfer many files at once. Upload and download whole directory structures. Use wildcards or file sets to specify which files to transfer. Monitor transfer progress with events.

Need to work with directories? List their content, create or rename them. You can even delete non-empty folders recursively (and handle symlinks properly) using a single line of code.

Rebex SFTP includes a standalone SSH client library. Need to execute a command on the SSH server or tunnel through it? Want to generate a key pair for SSH authentication? All included.

One of the main points of using SFTP is to ensure file transfers are secure and reliable. Rebex SFTP provides a rich set of security features. You'll find APIs for verifying server identity and fine-tuning SSH parameters. PKCS8, PuTTY and OpenSSH private key formats are supported. Even private keys stored on smart cards can be used.
