+\S{pscp-pubkey} Using public key authentication with PSCP
+
+Like PuTTY, PSCP can authenticate using a public key instead of a
+password. There are two ways you can do this.
+
+Firstly, PSCP can use PuTTY saved sessions in place of hostnames
+(see \k{pscp-usage-basics-host}). So you would do this:
+
+\b Run PuTTY, and create a PuTTY saved session (see
+\k{config-saving}) which specifies your private key file (see
+\k{config-auth}). You will probably also want to specify a username
+to log in as (see \k{config-username}).
+
+\b In PSCP, you can now use the name of the session instead of a
+hostname: \c{pscp sessionname:file localfile}.
+
+Secondly, PSCP will attempt to authenticate using Pageant if Pageant
+is running (see \k{pageant}). So you would do this:
+
+\b Ensure Pageant is running, and has your private key stored in it.
+
+\b Specify a user and host name to PSCP as normal. PSCP will
+automatically detect Pageant and try to use the keys within it.
+
+For more general information on public-key authentication, see
+\k{pubkey}.
