 - Pkzip uses the same encryption as 'cryptmethod' "zip", and US Govt has no
   objection to its export.  Pkzip's public file APPNOTE.TXT describes this
   algorithm in detail.
+- The implmentation of 'cryptmethod' "blowfish" has a flaw.  It is possible to
+  crack the first 64 bytes of a file and in some circumstances more of the
+  file. Use of it is not recommended, but it's still the strongest method
+  supported by Vim 7.3 and 7.4.  The "zip" method is even weaker.
 - Vim originates from the Netherlands.  That is where the sources come from.
   Thus the encryption code is not exported from the USA.
