<refsection><title>Description</title>
<para><command>nix-copy-closure</command> gives you an easy and
efficient way to exchange software between machines. Given one or
more Nix store paths <replaceable>paths</replaceable> on the local
machine, <command>nix-copy-closure</command> computes the closure of
those paths (i.e. all their dependencies in the Nix store), and copies
all paths in the closure to the remote machine via the
<command>ssh</command> (Secure Shell) command. With the
<option>--from</option>, the direction is reversed:
the closure of <replaceable>paths</replaceable> on a remote machine is
copied to the Nix store on the local machine.</para>
<para>This command is efficient because it only sends the store paths
that are missing on the target machine.</para>
<para>Since <command>nix-copy-closure</command> calls
<command>ssh</command>, you may be asked to type in the appropriate
password or passphrase. In fact, you may be asked
<emphasis>twice</emphasis> because <command>nix-copy-closure</command>
currently connects twice to the remote machine, first to get the set
of paths missing on the target machine, and second to send the dump of
those paths. If this bothers you, use
<command>ssh-agent</command>.</para>

<listitem><para>Let the sending machine cryptographically sign the

the target machine does not have direct access to the Nix store
(i.e., if the target machine has a multi-user Nix installation),
then the target machine will check the dump against
<filename>/nix/etc/nix/signing-key.pub</filename> before unpacking
it in its Nix store. This allows secure sharing of store paths
between untrusted users on two machines, provided that there is a
trust relation between the Nix installations on both machines
(namely, they have matching public/secret keys).</para></listitem>
