ssl

Quick and easy self signed ssl certificate

In many environments you can use ssl encryption, and you may skip the encryption because generating a cert or getting a lets encrypt cert would add more time to the thing your are working on. To overcome this security issue I wrote a small script to create a crt and key file. selfsigned.sh #!/bin/bash # fast ssl cert without ca ENDPOINT=$1 openssl genrsa -out $ENDPOINT.key 2048 openssl req -new -x509 -key $ENDPOINT.

Multiple flavours of nginx http to https redirects

Redirects in nginx are really powerful, here are some cool and common examples. all domains http > https and remove www Redirect all http traffic which has no other better matching server_name defined from www.domain.tld and domain.tld to https://domain.tld # redirect http://www to https non www # global and maybe not the best in all setups server { listen 80; server_name ~^(www\.)(?<domain>.+)$; return 301 https://$domain$request_uri; } http > https Redirect all of the incoming http requests to https for selected domains

Use a deafult cert for nginx

If you use a service like cloudflare or sucuri you don't need a valid cert on the backend servers to do full ssl to backend. If you want full ssl to the server you need 2 things self signed cert nginx proxy to send traffic to port 80 Using this method you need your application to send out redirects to ssl version of pages. Self signed crt You can gererate one with: selfsigned.

Comodo PositiveSSL CA Chain

This is the current PositiveSSL ca chain. Apache and Nginx seem to have different implementations on the chain order these are the right orders for PositiveSSL.

Let's Encrypt

![Let's encrypt] ({filename}/static/images/letsencrypt.svg) This Article is all about the SSL cert signing and auto signing for Let's Encrypt. I only cover nginx based setup and does require root and knowledge of some basic nginx vhost configuration. Let's start with what Let's Encrypt is and how to use it. It is a public CA that signs for free, there are some limits but reaching them is not likeley in most cases. To Get a valid cert they use their own application that is developed in tho open on this github page.
