Swift 3 Trusting a Self-Signed SSL Certificate

For testing purposes, we may want to have local testing servers using self-signed SSL certificate for HTTPS connection. Now, suppose we have a local server with self-signed certificate, establishing an actual HTTPS connection would require us to trust our self-signed certificate. It is easy on a browser: few clicks, and you will be on your way. But how about a Swift application?

Caution: Get an actual, trusted, signed certicate for production apps!

0. A regular HTTPS request

App Transport Security (ATS) is a technology that requires an app to either support best practice HTTPS security or statically declare its security limitations via a property in its Info.plist.

Client-side SSL

For excessively paranoid client authentication.

Convert SSL certificate from CRT format to PEM

openssl x509 -in server.crt -out server.der -outform DER
openssl x509 -in server.der -inform DER -out server.pem -outform PEM

	import { Buffer } from "buffer";

	var item: Office.MessageRead;
	Office.onReady(() => {
	item = Office.context.mailbox.item;
	});

	/**
	* Gets the email in EML format (IMF text file). This function executes the following steps:
	* (1) item.getAllInternetHeadersAsync()
