This tutorial will explain how to create a self-signed certificate that you will be able to use with apache in order to provide ssl support.
A self signed certificate won't provide as much security guarantees than a CA-signed certificate, but at least you will be able to use encrypted connection to your server.
In order to be able to create a certificate, you need to install openssl package:
$ sudo apt-get install openssl
Now you can create a self-signed certificate available for 365 days by typing the following:
$ sudo openssl req -new -x509 -days 365 -nodes -out /path/to/cert.pem -keyout /path/to/cert.pem
Generating a 1024 bit RSA private key
writing new private key to '/path/to/cert.pem'
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
Country Name (2 letter code) [AU]:IE
State or Province Name (full name) [Some-State]:
Locality Name (eg, city) :
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Example Ltd
Organizational Unit Name (eg, section) :
Common Name (eg, YOUR name) :example.com
Email Address :firstname.lastname@example.org
You can now use this certificate with application such as apache, courier ... to provide ssl support.
