WinSCP Technical Requirements

Using WinSCP, it is possible to connect to a SSH (Secure SHell) server with SFTP (SSH File Transfer Protocol) or SCP (Secure Copy Protocol) service, mainly to UNIX machines. SFTP is a standard part of SSH2 package. SCP is a standard part of SSH1 package. Both protocols can be run even on the latter SSH version. WinSCP supports both SSH1 and SSH2. For authentication, the user can use username and password or public key (RSA or DSA). Other supported means of authorization include TIS, Cryptocard and Keyboard-interactive.

To generate a public key file, use the PuTTYgen application. Also read how to use the Pageant application for public key authentication. (PuTTY’s SSH authentication agent). You can find links to download these programs in the “Download” section. The installation package of WinSCP already includes these applications.

The user can specify his/her encryption algorithm preferences. Options are: AES (SSH2-only), Blowfish, 3DES and DES (SSH1-only). It is possible to enable compression. A connection can be established through a Proxy (HTTP, SOCKS 4/5 or Telnet).
