I trying to use JSCH SFTP for transferring file from remote client to local host and vice versa. &nbsp;My problem is even after creating private key for the client using ssh-keygen -C &quot;user@hostID&quot; -t rsa, and adding &nbsp; jsch.addIdentity(privateKey, passphrase), during connection it show warning like :- 
 
&quot;The authenticity of host 'hostID' can't be established. 
RSA key fingerprint is xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx. 
Are you sure you want to continue connecting?&quot;. 
 
I know that including a statement &quot;config.put(&quot;StrictHostKeyChecking&quot;, &quot;no&quot;);&quot; will not show this warning but it may not be the best practice in terms of security. 
 
I'm using the following code as my reference:-

How to use JSCh for file transfer and download?

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Telnet is an application layer protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. SSH was designed as a replacement for Telnet and for unsecured remote shell protocols. The term telnet is also used to refer to the software that implements the client part of the protocol. SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server.
