Client certificate with Intermediate

Hi

Using WinSCP 6.3.5 to connect to a remote FTP Server using Explicit FTPS with mutual TLS.

This works fine when I configure a client certificate that has no Intermediate CA but I cannot get WinSCP to work when attempting to configure with a chained Intermediate.

The server is trusting the Root CA – I want to be able to configure WinSCP with a private key and chained client cert / intermediate cert, however when handshaking I can see that WinSCP is not including the intermediate when responding to the Certificate request from the server.

Does WinSCP support chaining Intermediates with client certs?

Thanks for any support..

To be honest, I do not know. In general client certificates are very rarely used, so I have little experience with them overall.

Does it work with other FTP clients?

Yeah it works fine with every other client I've tried.

Client certificates are often used with FTPS. Mutual TLS is generally the norm...

I'll have a look in your github project to try and find the answer.
