Curl with Java KeyStore

Curl doesn't have support for java keystore file, so therefor the file should be converted to a PEM format. It consists of the following multiple steps:

Convert keystore to p12 file
Convert p12 file to pem file
Run curl command with pem files

One way TLS/SSL/Authentication

Convert keystore to p12 file

I've spent the day trying to get this setup working with GitHub and given the number of gotcha's I encountered, it seemed like a good idea to document how I finally got this working with as few hacks as possible. There's a lot of documentation out there (some of it old and misleading) and committing here for posterity will help me remember this when I inevitably need to do this again.

Rationale

Passwords are simply not enough these days. Regardless of the company, breaches (and the associated Personally Identifiable Information harvested) are a matter of not if, but when. There are a number of things you can do to protect yourself, but being on the tin-foil-hat side of paranoia, means there are a few Commandents that I adhere to (and recommend for other folks)[Insert link to Fight Club Rules for the Secure Internet].

That being said, if you use 2-factor authentication and have committed to using a hardware token such as the Yubikey, then you're already ahead of the curve. The problem is that wh

uv

Experimental but very promising pip replacement that handles package managing as well as virtual environments and Python version management.

uv comes included with uvx, an alias for uv tool run. uvx allos you to install and execute command-line tools on an ephemeral environment.

Python versions

Note that you don't have to actively install a Python version! uv will automatically fetch the required Python version for your project.

	1) Create a branch with the tag
	git branch {tagname}-branch {tagname}
	git checkout {tagname}-branch

	2) Include the fix manually if it's just a change ....
	git add .
	git ci -m "Fix included"
	or cherry-pick the commit, whatever is easier
	git cherry-pick {num_commit}

	# Automated AMI Backups

	#
	# This script will search for all instances having a tag with the name "backup"
	# and value "Backup" on it. As soon as we have the instances list, we loop
	# through each instance
	# and create an AMI of it. Also, it will look for a "Retention" tag key which
	# will be used as a retention policy number in days. If there is no tag with
	# that name, it will use a 7 days default value for each AMI.
