There's one catch . If you are using the code on a test server with a self-signed certificate, it fails. In that case, I would suggest that you download the certificate from the server and import it to your keystore as a trusted key. You may also need to add a subject alternative name to the certificate if the host name does not match the certificate.
You may also choose to use a custom TrustManager and HostnameVerifier to ignore the certificate verification errors.

4. Import the registry entry.
5. Start the service with "net start ssh_tunnel" or from the services applet.
You may choose to use a batch file for srvany (instead of plink.exe ), but you won't be able to shut down the tunnel when you stop the service.
Also, if the Windows SYSTEM user cannot see the host key for SSH connection, the tunnel cannot be established.

Key points:
Java String.matches() matches the entire string, not a partial string. Use java.util.regex.Matcher.find() to match a partial String.
For case insensitive match, use Pattern.compile with case insensitive flags:
