winscp.com with key pairs

Hi. I have a server that authenticates ssh sessions using putty key pairs.

Is it possible to script the use of these keypairs using winscp.com and a script file?

I see that winscp.exe offers the option /privatekeyfile:xxxx
But I have not been able to find this option for winscp.com.

Any and all help is much appreciated.

Thanks

Use -privatekey switch of open command:

I cannot use the -hostkey option with the open command in a script.

When I try like this:

winscp.com /command "open sftp//username/password@ipaddress -hostkey ""ssh-rsa 1536 XX:XX:XX:XX:XX:XX:XX:XX:XX""" "get xxx" exit

I get the following error:

Too many parameters for command 'open'

I get the same error when I tried rearranging and placing the -hostkey option first, like this.

winscp.com /command "open -hostkey ""ssh-rsa 1536 XX:XX:XX:XX:XX:XX:XX:XX:XX"" sftp//username/password@ipaddress" "get xxx" exit

The exact same command like works without the -hostkey value, but only from my interactive session where I have the key stored. However, I need this to work from an automatically scheduled SSIS job, and it always fails to accept the key from the SFTP site since it runs from the SQLServerAGENT user.

I cannot use the -hostkey option with the open command in a script.
