How to set up git to use the GPG Suite

GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

  1. Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
  2. Create or import a key -- see below for https://keybase.io
  3. Run gpg --list-secret-keys and look for sec, use the key ID for the next step
  4. Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

System Design Cheatsheet

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

  1. Clarify and agree on the scope of the system
  • User cases (description of sequences of events that, taken together, lead to a system doing something useful)
    • Who is going to use it?
    • How are they going to use it?

It's not just superfish that's the problem.
Superfish uses an SDK from Komodia to do SSL MITM. That's probably known by now.
Superfish isn't the only product to use that sdk. there's others too.
Each product that uses the Komodia SDK to MITM, has its OWN CA cert and private
key pair. Seems a lot of people think they all use the superfish cert. That is
NOT the case.
First thing I checked was komodia's own parental control software,
Keep My Family Secure. (mentioned on komodia's own website).
