Hello. I try to connect to a host by using

com.sshtools.j2ssh

When i connect ssh.connect(hostname,portname)

i see in system.out log these messages;

The host key fingerprint is: 1024: XX XX XX XX XX XX XX XX XX X XX XX XX XX XX XX

Do you want to allow this host key? [Yes|No|Always]:

com.sshtools.j2ssh.transport.TransportProtocolClient verifyHostKey The host key was not accepted

I want to accept this key but i am not able to. Is there a method for accepting this key?

I searched for known_hosts file and adding this host key can fix my problem.

How do i add this key?

What is the format for adding the key manually?

must the line be like this?



hostname 1024: XX XX XX XX XX XX XX XX XX X XX XX XX XX XX XX

Thanks

I'm not sure if it applyes here, but you can imprt root certificates with keys in you JRE keystore or specify which keystore you're program will use. Try exploring keystores
