From 5494fc310acf0aabb9d828451331e44483eb21c7 Mon Sep 17 00:00:00 2001 From: Malfurious Date: Mon, 21 Oct 2024 11:09:00 -0400 Subject: Remove Crypto++ library The tracked version of Crypto++ is going on 10 years old and doesn't always compile properly on modern tooling. This removes the entire subdirectory as well as references to files in the build script. Due to the number of files touched by this commit, I opt to add its replacement in the next commit.
