That makes sense thanks for the update.

How did this work if there is no property for SslHostCertificateFingerprint?

The SslHostCertificateFingerprint was renamed to TlsHostCertificateFingerprint.

Re: Also getting regex exception

I am confused about the regex above. Both my fingerprint and the original question have 20 pairs of hex numbers, but the regex only matches 15. I am surprised that this is expected to work.

You are setting SshHostKeyFingerprint, but you are using FTP over TLS, not SSH. You need to set TlsHostCertificateFingerprint.

Also getting regex exception

Hey Prikryl,

For me adding the "ssh-rsa 2048" to the beginning of the string I assign to SshHostKeyFingerprint doesn't make the regex exception go away.

I can connect to the host with the UI, and also had some initial success using the scripting engine. I haven't been able to connect after that first time.

Now I am using the .Net library (Version 1.2.8.5316) in a .Net 4 console app. My OS is Win7 Pro.

Here is my SessionOptions: 

SessionOptions sessionOptions = new SessionOptions

{

   Protocol = WinSCP.Protocol.Ftp,

   FtpMode = WinSCP.FtpMode.Passive,

   PortNumber = 21,

   FtpSecure = FtpSecure.Explicit,

   HostName = "162.253.127.64",

   UserName = "--------",

   Password = "--------",

   SshHostKeyFingerprint = "ssh-rsa 2048 e7:d5:b0:a4:6f:24:7f:15:5c:c1:ae:b9:43:c1:86:95:7e:97:35:85"

};


When I run it, I get:
System.ArgumentException was caught
HResult=-2147024809
Message=SSH host key fingerprint "ssh-rsa 2048 e7:d5:b0:a4:6f:24:7f:15:5c:c1:ae:b9:43:c1:86:95:7e:97:35:85" does not match pattern /((ssh-rsa|ssh-dss)( |-))?(\d+ )?([0-9a-f]{2}(:|-)){15}[0-9a-f]{2}(;((ssh-rsa|ssh-dss)( |-))?(\d+ )?([0-9a-f]{2}(:|-)){15}[0-9a-f]{2})*/

I am confused about the regex above. Both my fingerprint and the original question have 20 pairs of hex numbers, but the regex only matches 15. I am surprised that this is expected to work.

Can you comment on the regex? Am I reading it wrong?

thanks

Re: SSL host certificate fingerprint Does Not Match

The code in the second post looks good. What's wrong with that? Or was that a resolution?

SSL host certificate fingerprint Does Not Match

C#.NET 4.0 WinSCP 5.1

When I use the GUI in the registry it creates:
FSProtocol 5
Ftps 1
PortNumber 990
FtpsCertificates: e6:a3:7a:56:5b:e3:bb:0d:1c:34:58:bd:47:94:79:75:32:2b:70:4d
And works fine

When I run in code I get:
SSL host certificate fingerprint "ssh-rsa 1024 e6:a3:7a:56:5b:e3:bb:0d:1c:34:58:bd:47:94:79:75:32:2b:70:4d" does not match pattern /([0-9a-f]{2}:){19}[0-9a-f]{2}/
for: 
SessionOptions sessionOptions = new SessionOptions

                {

                    Protocol = WinSCP.Protocol.Ftp,

                    FtpMode = FtpMode.Passive,

                    FtpSecure = FtpSecure.Implicit,

                    PortNumber = 990,

                    UserName = "--------",

                    Password = "--------",

                    HostName = "ftp.----.com",

                    SslHostCertificateFingerprint = "ssh-rsa 1024 e6:a3:7a:56:5b:e3:bb:0d:1c:34:58:bd:47:94:79:75:32:2b:70:4d"

                };


I get:

                    FtpSecure = FtpSecure.Implicit,

                    PortNumber = 990,

                    UserName = "--------",

                    Password = "--------",

                    HostName = "ftp.----.com",

                    SshHostKeyFingerprint = "ssh-rsa 1024 e6:a3:7a:56:5b:e3:bb:0d:1c:34:58:bd:47:94:79:75:32:2b:70:4d"

                };
