clevertonh / ev-ssl-ca-experiment.sh
Created January 18, 2020 20:39 — forked from Dan-Q/ev-ssl-ca-experiment.sh
Experiment to use OpenSSL to establish an EV-capable CA and issue illigitimate certificates which will be accepted and displayed as full valid EV certificates by Microsoft Internet Explorer and Edge on appropriately-configured Windows computers.
#!/bin/bash
# The following steps, which were tested on Ubuntu 18.04 LTS and on the Ubuntu-powered Linux for Windows Subsystem on Windows,
# will:
#
# * Compile a recent version of OpenSSL (you can skip this step and use your package maintainer's version if you prefer, but you
# might have to tweak a few bits)
# * Create a separate set of configuration files suitable for configuring a basic CA capable of signing EV certificates
# * Create such a CA (hackerca.local / HackerCA EV Root CA)
# * Create a certificate request for a site, hackersite.local, belonging to company "Barclays PLC [GB]"

NGINX tuning for best performance

Moved to git repository: https://github.com/denji/nginx-tuning

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
