openssl: check privkey, cert request, certificate

posted on 2016-02-26 13:50:50

Here is a one-liner that prompts you to enter the filenames of your private key, your certificate's request and your final certificate:

echo; echo $'\e[32;1m'"cd into keyfolder, enter filenames when prompted."$'\e[0m'; ls -lah; echo; read -p "privkey:  " fn; read -p "certreq:  " csr; read -p "certname: " cert; openssl rsa -in $fn -modulus -noout | openssl md5; openssl req -in $csr -modulus -noout | openssl md5; openssl x509 -in  $cert -modulus -noout | openssl md5'

Only if all hash value results are the same, your files will work. If they differ something is broken and you have to have a more in-depth look.

Apache redirect http traffic to https

posted on 2014-06-30 10:30:09

There are two approaches to this. Either use a redirect or a rewrite rule.

Rewrite, the officially recommended method

NameVirtualHost *:80
<VirtualHost *:80>
   ServerName mysite.example.com
   DocumentRoot /usr/local/apache2/htdocs 
   Redirect permanent / https://mysite.example.com/
</VirtualHost>

<VirtualHost _default_:443>
   ServerName mysite.example.com
  DocumentRoot /usr/local/apache2/htdocs
  SSLEngine On
 # etc...
</VirtualHost>

It's a little faster than a rewrite plus it is officially recommended. However behind a SSL offloader its said not to work, I read on stackoverflow. My guess would be this case could be fixed through the use of HTTP headers, but I currently have no setup where I can verify that without breaking things and wreaking havoc.

Rewrite, for completeness sake (and in case #1 did not work)

Use this in your vhost configuration:

RewriteEngine on
RewriteCond %{HTTPS} !=on
RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1  [R=301,L,QSA]

To redirect just specific http traffic concerning a specific folder, use a different rewrite rule:

RewriteRule ^/?name-of-your-folder/(.*) https://%{SERVER_NAME}/name-of-your-folder/$1 [R=301,L,QSA]
