commit 462d4097ce8b0059591b366c0ddb21b5efe97c3c Author: Suphanat Chunhapanya <haxx.pop(a)gmail.com> Date: Thu Apr 19 22:36:59 2018 +0700 hs-v3: Refactor secret data building logic Because this secret data building logic is not only used by the descriptor encoding process but also by the descriptor decoding, refactor the function to take both steps into account.
