From 528f526f6970499575712fd1db6610d773a0b80e Mon Sep 17 00:00:00 2001 From: Daniel Kahn Gillmor Date: Sun, 26 May 2019 18:15:57 -0400 Subject: [PATCH] cli/show: add tests for viewing protected headers Here we add several variant e-mail messages, some of which have correctly-structured protected headers, and some of which do not. The goal of the tests is to ensure that the right protected subjects get reported.
