Where to add SSH keys to allow connections to remote server on Android? I'm using a rooted custom Android kernel (Gingerbread), and am able to connect to a remote SSH server with password authentication using busybox and a terminal emulator app.  I would like to be able to use SSH keys for auto-login; is this possible?  If so, where should I put my private key?
It's not quite as seamless, but the ssh binary provided by busybox (mine, at least) supports the -i flag, so you can put the key wherever you want and use that:

ssh -i /path/to/key_file joeuser@somehost.com


The relevant man page entry for -i (with the caveat that the information about the default path may not be the same on Android):

-i identity_file

         Selects a file from which the identity (private key) for public
         key authentication is read.  The default is ~/.ssh/identity for
         protocol version 1, and ~/.ssh/id_dsa, ~/.ssh/id_ecdsa and
         ~/.ssh/id_rsa for protocol version 2.  Identity files may also be
         specified on a per-host basis in the configuration file.  It is
         possible to have multiple -i options (and multiple identities
         specified in configuration files).  ssh will also try to load
         certificate information from the filename obtained by appending
         -cert.pub to identity filenames.
