The SSH / SFTP .NET component provides two objects: A client-side SSH2 implementation for executing commands and shell sessions on Unix/Windows SSH servers, and an SFTP implementation for file transfer and remote file management over SSH.

It also provides SSH tunneling capabilities. (SSH tunneling (port forwarding) for IMAP, POP3, and SMTP is also integrated directly within the Chilkat IMAP and Email components.)
