I am following the example at http://winscp.net/eng/docs/scripting to automate the transfer of files from my PC to a sftp server however each time I include a password it fails to authenticate.

I am able to use the same password when using the WinSCP graphical user interface and when I explicitly type the password in the command line however not when I automate.

My code looks as follows

open sftp://user:password%21@example.com

I have followed the suggestion at http://winscp.net/eng/docs/session_url to encode special characters hence the %21 which symbolizes an exclamation mark. Interestingly enough the example on the page does not encode the exclamation mark e.g. 4pRte!ai%253@example.com

I have also tried using password! and that doesn't work either.

The issue was that it was expecting a password phrase for a private key which WinSCP doesn't support providing programmatically as per the FAQ at http://winscp.net/eng/docs/faq_passphrase.

The way around it was to use the Pageant agent that is provided with the WinSCP installation or as a standalone executable at http://winscp.net/eng/download.php. Hopefully this helps someone else in the future.
