+Subject: expose ripemd160
+
+This adds references to the decrepit/ module from non-decrepit source,
+which is not allowed in upstream. Until upstream has a way to interface
+with node.js that allows exposing additional digests without patching,
+this patch is required to provide ripemd160 support in the nodejs crypto
+module.
