For years now I’ve wanted a simple way to encrypt or decrypt a file in macOS, so this morning I built it. This takes five to ten minutes to setup, and provides the encryption service as a right-click menu item and a pair of folders with folder actions enabled. Here’s what I did.

I’ve seen quite a few smart people recommend using a VPN service in the wake of the U.S. government’s decision to repeal privacy rules for ISPs. Unfortunately, I find this advice to be a bit misguided, or at least ill-informed. You can move your risk around, but in the end this comes down to an issue of trust, and avenues of recourse.

Between 2000 and 2003 I was part of a small group that was responsible for the security of the network in a remote military base. The work we did there was foundational for the rest of my career, at least so far. Once a week our team shut down for the afternoon to do training, and in the training one of us was responsible for researching a topic in depth and then presenting it to the rest of the team. We built web servers, firewalls, and proxies with OpenBSD, managed our intrusion detection system that we designed and installed ourselves, we even built a honeypot to watch malicious traffic. We spent a lot of long nights, and did a lot of hard work, but it paid off.
