reqFTP.EnableSsl = true;

Question

Hi,

I'm using a hosting company that offers FTPS, but because the certificate is self signed it's coming up with an error.

Is it possible to bypass the certificate error (exception) and still login? I notice that with other FTP programs (FileZilla), you can choose to trust the certificate if it doesn't pass inspection.

 

thanks,

Ron

Answer 1

And which library are you using?

(If installing your certificate as a trusted one isn't an option, for .Net libs you would use the  ServicePointManager.ServerCertificateValidationCallback to plugin your own validator...)

Answer 2

 

Hi timvw,

Ops, yes that would have been a good thing to include )

The certificate error is "Self Signed Certificate". I'm just trying to use FTP over SSL to protect my FTP login ID and Password.

 

I'm using FtpWebRequest

I kept looking, and as you said... ServicePointManager, I did find this code on the web... and it does seem to work.

Is this the best way to go about it?

----------------------------------------------------------------------------------------------------------------------------

ServicePointManager.ServerCertificateValidationCallback = AcceptAllCertificatePolicy;

 

//Code to Accept All Certificates

public static bool AcceptAllCertificatePolicy(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)

{

return true;

}

 

Thanks,

Ron

Answer 3

As long as you're not doing anything else your code would be enough... But I would probably only return true if the certificate is your own self-signed certificate and in all other cases rely on default validation...

I wish, more people would do just that.

And, in that case a self-signed certificate is just as good as one, that makes rich people richer !
