+\S{faq-export-cert}{Question} Can you provide us with export control
+information / FIPS certification for PuTTY?
+
+Some people have asked us for an Export Control Classification Number
+(ECCN) for PuTTY.  We don't know whether we have one, and as a team of
+free software developers based in the UK we don't have the time,
+money, or effort to deal with US bureaucracy to investigate any
+further.  We believe that PuTTY falls under 5D002 on the US Commerce
+Control List, but that shouldn't be taken as definitive.  If you need
+to know more you should seek professional legal advice.  The same
+applies to any other country's legal requirements and restrictions.
+
+Similarly, some people have asked us for FIPS certification of the
+PuTTY tools.  Unless someone else is prepared to do the necessary work
+and pay any costs, we can't provide this.
