+Title: Hide Tor Platform Information
+Version: $Revision$
+Last-Modified: $Date$

+Status: Draft

+
+                      Hiding Tor Platform Information
+
+0.0 Introduction
+
+The current Tor program publishes its specific Tor version and related OS
+platform information. This information could be misused by an attacker.
+
+0.1 Current Implementation
+
+Currently, the Tor binary sends data that looks like the following:
+
+    Tor 0.2.0.26-rc (r14597) on Darwin Power Macintosh
+    Tor 0.1.2.19 on Windows XP Service Pack 3 [workstation] {terminal services,
+    single user}
+
+1.0 Suggested changes
+
+It would be useful to allow a user to configure the disclosure of such
+information. Such a change would be an option in the torrc file like so:
+
+    HidePlatform Yes
+
+1.1 Suggested default behavior in the future
+
+If a user would like to disclose this information, they could configure their
+Tor to do so.
+
+    HidePlatform No
+
