Prerequisites

Windows

This document is written assuming that the OS is Windows.

Chocolatey

Chocolatey is a package manager for Windows (like apt-get or yum but for Windows). Link to install Chocolatey: https://chocolatey.org/install

OpenSSL

OpenSSL is a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. Installation:

choco install openssl.light

Step 1: Create a Private Key

Run the command:

"C:\Program Files\OpenSSL\bin\openssl.exe" genrsa -des3 -out rootSSL.key 2048

Enter a Password:

Enter pass phrase for rootSSL.key:

Verify the Password:

Verifying - Enter pass phrase for rootSSL.key:

Step 2: Create a Certificate File

Run the command:

"C:\Program Files\OpenSSL\bin\openssl.exe" req -x509 -new -nodes -key rootSSL.key -sha256 -days 1024 -out rootSSL.pem

Enter the Password:

Enter pass phrase for rootSSL.key:

Enter your Country's 2-Letter Code:

Country Name (2 letter code) [AU]:CA

Enter the name of your state/province:

State or Province Name (full name) [Some-State]:Quebec

Enter the name of your locality (city):

Locality Name (eg, city) []:montreal

Enter the name of your organization:

Organization Name (eg, company) [Internet Widgits Pty Ltd]:Unity

Enter the name of your business unit within the organization:

Organizational Unit Name (eg, section) []:Verticals

Enter your computer's fully qualified domain name or your name:

Common Name (e.g. server FQDN or YOUR name) []:Tony

Enter your e-mail address:

Email Address []:anthonyma@unity3d.com

Step 3: Get Windows to Trust the Certificate Authority (CA)

Search for and run Microsoft Management Console (mmc.exe)
Go to File > Add/Remove Snap-in...
Click on Certificates and then Add >
Select Computer Account and then Next >
Select Local computer (the computer this console is running on) and then Finish
Select OK in the Add or Remove Snap-ins window
Expand Console Root > Certificates (Local Computer) in the Console1 - [Console Root] window
Select Trusted Root Certification Authorities then Right-Click on Certificates and select All Tasks > Import...
Select Next in the Certificate Import Wizard window
Browse to the location of the rootSSL.pem file created in Step 2 and then select Next.
Select Place all certificates in the following store and ensure that Trusted Root Certification Authorities is the value in the Certificate store: field, and then select Next.
Select Finish.

Step 4: Create a Local Domain Site

Add 127.0.0.1 client-1.local to your C:\Windows\System32\drivers\etc\hosts file.

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#   127.0.0.1       localhost
#   ::1             localhost

127.0.0.1 client-1.local
# End of section

Step 5: Create a Private Key (`client-1.local.key`) and Certificate Request (`client-1.local.csr`) for the New Domain

Execute this command ensuring the following fields are the same as the ones you used in Step 1: Create a Private Key:

C=CA (Country)
ST=Quebec (State)
L=montreal (Locale)
O=Unity (Organization)
OU=Verticals (Business Unit)
CN=Tony (Name)

emailAddress=anthonyma@unity3d.com (E-Mail)

"C:\Program Files\OpenSSL\bin\openssl.exe" req -new -sha256 -nodes -out client-1.local.csr -newkey rsa:2048 -keyout client-1.local.key -subj "/C=CA/ST=Quebec/L=montreal/O=Unity/OU=Verticals/CN=Tony/emailAddress=anthonyma@unity3d.com"

Step 6: Issue the New Certificate (`client-1.local.crt`)

Execute the command:

"C:\Program Files\OpenSSL\bin\openssl.exe" x509 -req -in client-1.local.csr -CA rootSSL.pem -CAkey rootSSL.key -CAcreateserial -out client-1.local.crt -days 500 -sha256 -extensions "authorityKeyIdentifier=keyid,issuer\n basicConstraints=CA:FALSE\n keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment\n  subjectAltName=DNS:client-1.local"

Enter the password:

Enter pass phrase for rootSSL.key:

Step 7: Run the `webserver.exe`
