# Recommended SSL Settings for Nginx Sites
# ----------------------------------------
# Last Updated: 2019-07-04
# globalssl.conf
# Global ssl configuration file.
# Should be included in each and every server {} block of your https/ssl sites.
# Only use this if you know what you are doing with SSL, this is merely an example of
# good SSL settings for nginx ssl sites.
# NO SUPPORT IS OFFERED IN THIS REPO FOR SETTING UP AND RUNNING SSL
# There is lots of help for Let's Encrypt at: https://community.letsencrypt.org/
# To use this set of rules, add the include below into each server block.
# add this at the very top of your HTTPS server blocks before any other location rules
# include /etc/nginx/ssl.d/globalssl.conf;
##
# DIFFIE HELMAN ENCRYPTION / DHE
##
# Diffie-Hellman parameter for DHE ciphersuites, recommended 4096 bits
# Requires generating your dhparam.pem
# INSTRUCTIONS:
# -------------
# cd /etc/nginx/ssl
# sudo openssl dhparam -out dhparam.pem 4096
# WAIT FOR IT TO FINISH - Can take a long time
ssl_dhparam /etc/nginx/ssl/dhparam.pem;
##
# SSL SESSION SETTINGS
##

##
# SSL PROTOCOL SUPPORT
# Support modern and intermediate browsers
# If you want to allow some older browsers add TLSv1 (but then you will need to review the ciphers below and use the OLD set of ciphers from Mozilla)
##
ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3;
##
# -----------
# SSL CIPHERS
# -----------
# Ciphers below are the strongest and most recommened set as of 2019-07-04 (cipher recommendations change regularly)
# This is my own set of ciphers based on recommendations from https://www.immuniweb.com/ssl/
# and https://www.ssllabs.com/ssltest/
# You can optionally use ciphers recommended by https://mozilla.github.io/server-side-tls/ssl-config-generator/
# As we approach wider implementation and use of TLSv1.3 things will change even more
# As of this version and writing - Nginx only supports TLSv1.3 with openssl 1.1.1+

##
# CIPHER COMPLIANCE
# ------------------------------------
# COMPLIANT to PCI DSS compliance
# COMPLIANT to HIPAA guidance
# COMPLIANT to NIST guidelines
# COMPLIANT to industry best practices
# ------------------------------------
##
# Enable modern TLS cipher suites - without ECDHE-RSA-CHACHA20-POLY1305 (POLY1305 is not recommended anymore)
# This cipher set is highly tested and supports modern and older clients without using weak ciphers of any sort
