Examples of How to Derive a Signing Key for Signature Version 4 (AWS) for Google Apps Script

This is a sample script for "Examples of How to Derive a Signing Key for Signature Version 4" using Google Apps Script.

In order to use AWS SDKs, there are the sample scripts for the languages of Java, .NET (C#), Python, Ruby, JavaScript (Node.js). But the sample script of Google Apps Script is not prepared. I saw the question related to this at Stackoverflow. So I would like to also introduce the sample script here.

In the sample scripts, the input values are as follows.

key = 'wJalrXUtnFEMI/K7MDENG+bPxRfiCYEXAMPLEKEY'

If anyone is interested in setting up their system to automatically (or manually) sign their git commits with their GPG key, here are the steps:

Generate and add your key to GitHub
$ git config --global commit.gpgsign true ([OPTIONAL] every commit will now be signed)
$ git config --global user.signingkey ABCDEF01 (where ABCDEF01 is the fingerprint of the key to use)
$ git config --global alias.logs "log --show-signature" (now available as $ git logs)
$ git config --global alias.cis "commit -S" (optional if global signing is false)
$ echo "Some content" >> example.txt
$ git add example.txt
$ git cis -m "This commit is signed by a GPG key." (regular commit will work if global signing is enabled)

Methods of Signing with GPG

Last updated March 28, 2021

There are now two ways to approach this:

Using gpg and generating keys
Using Kryptonite by krypt.co

This Gist explains how to do this using gpg in a step-by-step fashion. Kryptonite is actually wickedly easy to use-but you will still need to follow the instructions

New Mac Setup

This gist documents the setup of my Mac, primarily for personal use and data science.

Hardware/software details:

MacBook Air (M1, 2020)
Big Sur (11.2.2)

Installs

Install HomeBrew

Install and Create Emulators using AVDMANAGER and SDKMANAGER

TL;DR

For generic skin emulator with default apis (without google apis):

List All System Images Available for Download: sdkmanager --list | grep system-images
Download Image: sdkmanager --install "system-images;android-29;default;x86"
