Please let me know how can i implement public/private key authorization.
The easiest way to do this, just to try it out, is to put the files in the Resources folder in your xcode project. This will result in them being copied into the application bundle. You can then open them with this example code:
privkey = [[NSBundle mainBundle] pathForResource: @"ipad" ofType: @"key"
inDirectory: @""];
pubkey = [[NSBundle mainBundle] pathForResource: @"ipad" ofType: @"pub"
inDirectory: @""];
rc = libssh2_userauth_publickey_fromfile(session,
"mellon", [pubkey UTF8String],
[privkey UTF8String], "");
However, obviously this won't work for production use, since the user needs to set up their own key. For that, I think the right solution is to port the ssh-keygen functionality and generate the key on the iPad; any other solution is going to be impractical, because it will rely on some resource the user may or may not have (a machine that can run ssh-keygen), and on a secure path between the user's machine and the machine that generated the key, which is a bit of a chicken-and-egg problem. You could use iTunes file transfer for this, but I don't think it's at all secure.
I'm working on an app for iPad that uses libssh2 as well, and so I'm running into similar problems--if I come up with a solution I'll let you know.
