+.Sh CAVEATS
+The keys produced by this process are stripped of all identifying
+information, including certifications, self-signatures, etc. This is
+intentional, since ssh attaches no inherent significance to these
+features.
+.Pp
+.Nm
+only works with RSA or DSA keys, because those are the
+only ones which work with ssh.
+.Pp
+Assuming a valid key type, though,
+.Nm
+will produce output for
+any requested key. This means, among other things, that it will
+happily export revoked keys, unverifiable keys, expired keys, etc.
+Make sure you do your own key validation before using this tool!
