Add support for native image
Description
Add graalvm reachability metadata to the project.
Motivation
Due to the heavy use of reflection, it is currently very hard to use sshd in native images. With reachability metadata, any application that consumes this library would automatically include the necessary classes and resources to create a native image.
Alternatives considered
Alternatively, metadata can be contributed to the reachability metadata repository.
Additional context
No response
Hi @gbaso
Did you manage to actually get an apache mina sshd build working with native image? I'm getting a lot of reflection issues related to bouncycastle, JceRandom, and Log4j?

there is some weirdness logging in so something in the build is not right.
[root@bob foo]# sftp root@localhost:2222
Warning: Permanently added 'localhost' (ECDSA) to the list of known hosts.
root@localhost's password:
Connected to localhost.
File "/root/2222" not found.
[root@bob foo]# mkdir -p /root/2222
[root@bob foo]# sftp root@localhost:2222
Warning: Permanently added 'localhost' (ECDSA) to the list of known hosts.
root@localhost's password:
Connected to localhost.
Changing to: /root/2222
sftp> ls -l
sftp> pwd
Remote working directory: /root/2222
In this case I am using a virtual file system so the user should be sandboxed to another folder but that doesn't happen. The '2222' is weird too that is the port that the user logged in under.
Another issue that can be seen is when logging in. In my code I have
sshd.setPasswordAuthenticator(new LoggingPasswordAuthenticator());
Which is just letting all users login without any password.
import org.apache.sshd.server.auth.AsyncAuthException;
import org.apache.sshd.server.auth.password.PasswordAuthenticator;
import org.apache.sshd.server.auth.password.PasswordChangeRequiredException;
import org.apache.sshd.server.session.ServerSession;
public class LoggingPasswordAuthenticator implements PasswordAuthenticator {
@Override
public boolean authenticate(String username, String password, ServerSession session) throws PasswordChangeRequiredException, AsyncAuthException {
return true; // Authentication with our dummy server always fails
}
}
however when actually testing it I have to use the actual password for the user or I get permission denied.
[root@bob foo]# sftp root@localhost:2222
Warning: Permanently added 'localhost' (ECDSA) to the list of known hosts.
root@localhost's password:
Permission denied, please try again.

With the help of the tracing agent I was able to get my application to work. I'm on java 21. YMMV.
First, you need to add the following flags to the image builder: -H:-AddAllFileSystemProviders --strict-image-heap.
Then register the resources (not sure if necessary):
- META-INF/services/org.apache.sshd.common.io.IoServiceFactoryFactory
- META-INF/services/java.nio.file.spi.FileSystemProvider
- META-INF/services/org.apache.sshd.server.subsystem.SubsystemFactory
- **/sshd-version.properties
Proxies:
- org.apache.sshd.common.session.SessionListener
- org.apache.sshd.common.channel.ChannelListener
- org.apache.sshd.common.forward.PortForwardingEventListener
Classes:
- java.security.KeyFactory
- java.security.KeyPairGenerator
- java.security.MessageDigest
- java.security.Signature
- java.security.interfaces.ECPrivateKey
- java.security.interfaces.ECPublicKey
- java.security.interfaces.RSAPrivateKey
- java.security.interfaces.RSAPublicKey
- javax.crypto.KeyAgreement
- org.apache.sshd.common.io.nio2.Nio2ServiceFactoryFactory
- org.apache.sshd.common.session.SessionListener
- org.apache.sshd.common.util.security.SunJCESecurityProviderRegistrar
- org.apache.sshd.common.util.security.bouncycastle.BouncyCastleSecurityProviderRegistrar
- org.apache.sshd.common.util.security.eddsa.EdDSASecurityProviderRegistrar
Hope this helps, at least as a starting point.

Alternatively, metadata can be contributed to the reachability metadata repository.
I think that would be the way to go. I know that there's a lot of reflection going on in Apache MINA sshd, especially in the area of SecurityProviders, and the proxying of various listeners.
But we will not be able to maintain any such metadata when our code changes. Better have such metadata be maintained where it is used, per version of the library, i.e., in the reachability metadata repository.
