NAME

       SSH - The ssh application implements the SSH (Secure Shell) protocol and
         provides an SFTP (SSH File Transfer Protocol) client and server.

DEPENDENCIES

       The  ssh  application  uses  the  Erlang  applications  public_key  and  crypto to handle public keys and
       encryption, hence these applications needs to be loaded for the ssh application to work. In  an  embedded
       environment that means they need to be started with application:start/[1,2] before the ssh application is
       started.

CONFIGURATION

       The ssh application does not currently have an application specific configuration file  as  described  in
       application(3erl),  however  it  will  by  default  use  the  following configuration files from openssh:
       known_hosts, authorized_keys, authorized_keys2, id_dsa and id_rsa, ssh_host_dsa_key and ssh_host_rsa_key.
       By  default  Erlang  SSH will look for id_dsa, id_rsa, known_hosts and authorized_keys in ~/.ssh, and the
       host key files in /etc/ssh . These locations may be changed  by  the  options  user_dir  and  system_dir.
       Public  key  handling  may  also  be customized by providing a callback module implementing the behaviors
       ssh_client_key_api and ssh_server_key_api.

   PUBLIC KEYS
       id_dsa and id_rsa are the users private key files, note that the public key is part of the private key so
       the  ssh  application  will not use the id_<*>.pub files. These are for the users convenience when he/she
       needs to convey their public key.

   KNOW HOSTS
       The known_hosts file contains a list of approved servers and their public keys. Once a server is  listed,
       it can be verified without user interaction.

   AUTHORIZED KEYS
       The  authorized  key  file  keeps track of the user's authorized public keys. The most common use of this
       file is to let users log in without entering their password which is supported by the Erlang SSH daemon.

   HOST KEYS
       Currently  rsa  and  dsa  host  keys  are  supported  and  are  expected  to  be  found  in  files  named
       ssh_host_rsa_key and ssh_host_dsa_key.
