From 753149d97f8474ff8745a66175b8e4a19fe50743 Mon Sep 17 00:00:00 2001 From: Richard Levitte Date: Wed, 10 Jul 2019 20:25:03 +0200 Subject: [PATCH] Move the code for 'openssl list' to its own translation unit. That makes it easier to work with than going through apps/openssl.c This also moves the implementation of calculate_columns() and makes it generally accessible.
