ssh2_publickey_init - Initialize Publickey subsystem

SYNOPSIS
       resource ssh2_publickey_init (resource  $session)

DESCRIPTION
	Request the Publickey subsystem from an already connected SSH2 server.

	The  publickey	subsystem  allows an already connected and authenticated client to manage the list of authorized public keys stored on the
       target server in an implementation agnostic manner. If  the  remote  server  does  not  support	the  publickey	subsystem,  the  ssh2_pub-
       lickey_init(3) function will return FALSE.

PARAMETERS
	      o $session
		-

RETURN VALUES
	Returns an SSH2 Publickey Subsystem resource for use with all other ssh2_publickey_*() methods or FALSE on failure.

NOTES
       Note

	      The  public key subsystem is used for managing public keys on a server to which the client is already authenticated. To authenticate
	      to a remote system using public key authentication, use the ssh2_auth_pubkey_file(3) function instead.
