I have been using the SFTP component for some time with no issues, however the server I have been connecting to has upgraded Open SSH to version SSH-2.0-OpenSSH_6.6.1 and users are now unable to authenticate.

The connection works when using putty and the same key.

When calling AuthenticatePk, the following error occurs.

  sshAuthenticatePk(47ms):
      requestUserAuthService(47ms):
        sendServiceRequest:
          svcName: ssh-userauth
          SentServiceReq: ssh-userauth
        --sendServiceRequest
        sshReadMessage(47ms):
          This is the 1st block after the key exchange.
          mType: DISCONNECT
          Received DISCONNECT message
          DisconnectReason: Packet corrupt
          terminateConnection(15ms):
            TCP connection cleanly closed by peer.
            Cleanly terminated TCP connection.
          --terminateConnection
        --sshReadMessage
        Error reading service accept.
      --requestUserAuthService
    --sshAuthenticatePk

Here is the full LastErrorMessage including the connection

If you wish, I can test by connecting and attempting to authenticate with your SSH server, but with an intentionally invalid key. This would probably reproduce the problem. Chilkat does not generally like to connect to customer servers without permission, even if the IP address is published and accessible..
