Hi,

I'd like to use winscp but do not have a fingerprint. Yes, I know that's a security risk but not where I use it.

This is the tool https://gallery.technet.microsoft.com/WinSCP-PowerShell-Module-ee1601ff



How can I find a way around it?

What protocol are you using, SFTP or SCP?  If SFTP, you can switch to just the FTP protocol and then no finger print is required.

Can you post the script throwing the error?

Not sure, the default one, guess that's scp.
There is no error, it just asks for a fingerprint which I do not have.

To quote the WinSCP website:


WinSCP is a popular SFTP client and FTP client for Microsoft Windows!
Copy file between a local computer and remote servers using
FTP, FTPS, SCP, SFTP, WebDAV or S3 file transfer protocols.

So yes, WinSCP can be used with several file transfer protocols, FTP being one of them.

Apparently we use sftp, what is not working with the commands here.

$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::sFtp
        HostName = $ftpServer
        PortNumber = 22
        UserName = $userName
        Password = $passWord
}

Error is:
SessionOptions.Protocol is Protocol.Sftp or Protocol.Scp, but SessionOptions.SshHostKeyFingerprint is not set. (raised by: New-WinSCPSession)

New-WinSCPSession -SessionOption $sessionOptions
