How to create a self-signed SSL Certificate with SubjectAltName(SAN)

After Chrome 58, self-signed certificate without SAN is not valid anymore.

Step 1: Generate a Private Key

openssl genrsa -des3 -out example.com.key 2048

Step 2: Generate a CSR (Certificate Signing Request)

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

~~Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.~~

Synopsis

At the top of the file there should be a short introduction and/ or overview that explains what the project is. This description should match descriptions added for package managers (Gemspec, package.json, etc.)

Code Example

Show what the library does as concisely as possible, developers should be able to figure out how your project solves their problem by looking at the code example. Make sure the API you are showing off is obvious, and that your code is short and concise.

	CVE-2020-11976 - Apache wicket LFI / markup source file read vulnerability
	------------------------------------------

	By crafting a special URL it is possible to make Wicket deliver unprocessed HTML templates.
	This would allow an attacker to see possibly sensitive information inside a HTML template that is usually removed during rendering.
	Affected are Apache Wicket versions 7.16.0, 8.8.0 and 9.0.0-M5

	For example if there are credentials in the markup which are never supposed to be visible to the client:

	<wicket:remove>

	wget https://storage.googleapis.com/golang/go1.10.1.linux-armv6l.tar.gz
	sudo tar -C /usr/local -xvf go1.10.1.linux-armv6l.tar.gz
	cat >> ~/.bashrc << 'EOF'
	export GOPATH=$HOME/go
	export PATH=/usr/local/go/bin:$PATH:$GOPATH/bin
	EOF
	source ~/.bashrc
