I'm just wondering that, private key will be on server which is the machine which runs virtual terminal. So, the computer to which i need remote access will be having private key. Public key will be on my iPhone device from which i need to set remote access. What will be passphrase? do i need to specify it? And how libssh2 will access public and private keys from filename or path only? Are they both will be on server, i.e. the machine on which i need to setup remote access?

I need to implement functionality that when user inputs no password and specified the private key file, ssh must authenticate the user without password.

Please suggest something. I think i'm getting confused between public/private keys and how to set up remote connection between two devices with keypair.
