/*
This is a script for generating AuthorityInfoAccess (AIA) x.509 certificate extension value. 
AIA can contain CA certificate URi and OCSP URI.

This script has 2 sections. Do not touch the first section, customize the second section.
Then just copy it to a browser JavaScript console (F12 in my favorite browsers).

It has some limitations. If you hit them or find a bug, let me know.
For example, I didn't find what the AIA structurce should look like in the case of multiple OCSP URIs or multiple CA certificate URIs. If you need it, find me a valid AIA value example.
