I registered with a vpn service provider and the gave me these files to connect to there server. client.key, ta.key, ca.crt and client.crt how can i login the server using these certificates? Here is my code:
Public Class Form1
Private Sub newButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles newButton.Click
Dim VpnName As String = "Tunnel"
Dim Destination As String = "76.**.**.**"
Dim PresharedKey As String = "Don't know what to put here"
Dim PhoneBook As New RasPhoneBook
Dim VpnEntry As RasEntry = RasEntry.CreateVpnEntry(VpnName, Destination, DotRas.RasVpnStrategy.PptpOnly, DotRas.RasDevice.Create(VpnName, DotRas.RasDeviceType.Vpn))
VpnEntry.Options.RemoteDefaultGateway = False
VpnEntry.EncryptionType = RasEncryptionType.Optional
VpnEntry.Options.RequireDataEncryption = False
VpnEntry.Options.ShowDialingProgress = False
VpnEntry.Options.PreviewUserPassword = False
VpnEntry.PhoneNumber = Destination

If you were going to use a preshared key, that would need to be identified before hand and you'd know what value to use. The preshared key may be what's in the client.key file, though I don't know. You'd need to work out which values are contained in which
As for your certs, DotRas only has limited support for certificates... the EAP mechanism it uses is not very well documented and there are some known problems around using certificates with DotRas. I did my best to get the support added, but without any
real way of testing it (I couldn't get the certificate based server to work with clients I was using) I can't guarantee anything will work.
For configuring the entry, you'd be better off creating the entry through the Windows "Add new connection" interface than trying to guess which settings you need to use. Once you have the connection authenticating to the server and allowing you to connect
correctly from that generated entry, look at that entry in code, copy the settings down, and replicate those settings in your code. Also, you'll probably need to install the ca.crt and client.crt files on the machine in order for the certificates to be picked
