The server determines that you have your private key using your public key--it never sees the private key. The iPhone has the private key. If you use a passphrase, the user types it on the iPhone, and it is only used in libssh2_userauth_pubkey_*, never sent to server.

If you didn't encrypt the key, you don't need the passphrase--just use an empty string as on the example I sent.

The real trick on the iPhone is getting the public/private key pair there in the first place.
