    Ron's version: http://dev.ronware.org/p/vim/finfo?name=gvim.nsi
 - Also crypt the swap file, each block separately.  Change mf_write() and
     mf_read().  How to get b_p_key to these functions?
+    Generate seed for each block, store in pointer block.  Block 1 is not
+    encrypted.
+    When changing the password need to read back with the old password and
+    write again with the new one.
+    Verify recovery works.
+- Update for crypt code to use salt. (Mohsin May 30)
+    Make the strengthen_key value configurable and store it in the header.
 - Do profiling on sha256 code to find obvious bottlenecks.
