Since I started in IT and Networking, I have discovered that there are many things that result easier to do on a MAC, than any other OS. However we have to give credit where credit is due, Windows is doing a fantastic job with their new OS, but I still prefer MAC ;).
This post is dedicated to a paged referred from a colleague at my job on Cisco VCS Expressway configuration:
@gnowynnad Does a really good job at explaining the whole process of configuring VCS Expressway for MRA, and he also creates does a good job at explaining how to use OpenSSL to create your certificates:
This is what worked for me and wanted to share it:
CREATE DIRECTORIES
mkdir demoCA
cd demoCA
mkdir certs
mkdir newcerts
mkdir private
touch index.txt
echo 10 > serial
Copy /System/Library/OpenSSL/openssl.cnf to the demoCA directory, rename it to openssl_local.cnf
Modify openssl_local.cnf, under
[CA_default] section
“copy_extensions = copy” does not have a # at the beginning of the line.
“policy = policy_match” to “policy = policy_anything”
Creating these certificates and signing them your self for testing helps you get quicker when implementing these type of projects. Some times clients delay the purchase of a Public certificate and your deployment will also delay.
Certificates can be a daunting task if you have not good understanding of how they work. If you are interested in learning more about it, get started with this link:
