+\dd Private key file for user authentication.

+\dt \cw{\-hostkey} \e{key}
+
+\dd Specify an acceptable host public key. This option may be specified
+multiple times; each key can be either a fingerprint (\cw{99:aa:bb:...}) or
+a base64-encoded blob in OpenSSH's one-line format.
+
+\lcont{ Specifying this option overrides automated host key
+management; \e{only} the key(s) specified on the command-line will be
+accepted (unless a saved session also overrides host keys, in which
+case those will be added to), and the host key cache will not be
+written. }
+
+\dt \cw{\-sshlog} \e{logfile}
+
+\dt \cw{\-sshrawlog} \e{logfile}
+
+\dd These options make \cw{psftp} log protocol details to a file.
+(Some of these may be sensitive, although by default an effort is made
+to suppress obvious passwords.)
+
+\lcont{
+\cw{\-sshlog} logs decoded SSH packets and other events (those that
+\cw{\-v} would print). \cw{\-sshrawlog} additionally logs the raw
+encrypted packet data.
