WinSCP supports file certificates only.
Anyway, I have sent you an email with a development version of WinSCP to address you have used to register on this forum.

Hello,

I also am working on a particular use case with a need for client certs on implicit FTPS connections.

If possible, I'd like to test the 5.8 version for our particular case : cert and its key are located either on a smart-card, or a USB dongle.

Thanks a lot !

There are no client certificates in proper SSH.

What a pity. It works like a charm.

I read the following:

SSL means “Secure Sockets Layer”. Many protocols — like HTTP, SMTP, FTP, and SSH ‘“ were adjusted to include the support of SSL. Basically, it works as a tier in a certain protocol to provide cryptographic and security functions.


The combination of certificates and SSH is very powerful. There is no need any more for users to copy their public keys to the server. The Certificate issuer (CA / signer) can make the certificate valid for a limited time period. SSH options can be allowed or disallowed per certificate. It's great.

I'm trying to make an SFTP connection with a server signed client certificate.
I've already tested it, and it works on Linux with:
sftp -i <client_key> marty@10.0.0.2

The Linux sftp client expects the following naming convention in order for the client to pick up the certificate and its complementary private key:
<client_key> (private key)
<client_key>.pub (public key)
<client_key>-cert.pub (CA signed public key)

How does it work with WinSCP (version 20150710r)?
I expect it will be needing access to the certificate and its private key.
How do I have to supply those?
(BTW The SFTP server only allows authentication with client certificates.)

For SSH/SFTP, you use private keys, which WinSCP always supported (-privatekey).

You just have to convert the key to .ppk format.

Use PuTTYgen:

When I try it with openssh generated keys, I get the following:

Why? The point of the passphrase is to have the key protected. Yet, you are willing to have WinSCP remember the password, effectively breaking this. What's the difference?

Just one question.. Every time I set up a connection it asks me for the client certificate password. Is there a way to make WinSCP remember it?

Did you consider saving the certificate without passphrase?

It's -clientcert and -passphrase.
Though in your build it was -clientcertificate.
I'm sending you the latest build that will match a future production version.

Hi, thank's
allthough I haven't recieved it yet.
If you've sent the program itself rather then a link, it is probably halted by our security scanner on the mail.
It will take some time to get it released, so I can use it.
As soon as I've got it, I will let you know if it works allright.
