Securing all of your sub-domains is easy when you use a wildcard SSL

Wildcard SSL certificates are a convenient and most cost-effective option that allows you to secure a main domain – also known as a Fully Qualified Domain Name or FQDN and an unlimited number of subdomains.

Wildcard SSL certificates do it all at once for an unlimited number of sub-domains.

This makes wildcard certificates one of the best values available if you are looking to secure multiple sub-domains without having to purchase an individual certificate for each one.

There are people who will buy wildcard SSL even if they only have one domain to secure at the moment because you never know what the future holds.

Wildcard SSL Certificate is a marginal cost to future-proof your website to ensure a completely secure website experience as your site grows and also simplifies the management of your SSL certificates. It is the one with an asterisk – *.yourwebsite.com

Wildcard SSL / TLS certificates come in two varieties – Domain Validation – DV and Organisation Validation – OV

What is a Wildcard SSL Certificate?

one certificate to protect multiple domains or multiple uses.

Wildcard SSL Certificate is one of the many options for multiple-use SSL certificates. Along with other options on the market such as multi-domain (SAN) SSL certificate and Unified Communications Certificate – UCC, these certificates are similar in terms that they can protect multiple domains with just a single issued certificate.

This means one certificate to protect multiple domains or multiple uses. The way to implement a Wildcard SSL Certificate is effortless and straightforward.

All that is required during the configuration process of the Certificate Signing Request – CSR, is for the admin to add an asterisk in front of the main domain that requires protection in the Fully Qualified Domain Name – FQDN slot.

Therefore a Wildcard SSL Certificate with *.yourdomain.com can protect unlimited subdomains as shown below:

  www.yourdomain.com

  yourdomain.com

  blog.yourdomain.com

  mail.yourdomain.com

  dashboard.yourdomain.com

  anything.yourdomain.com

  support.yourdomain.com

  shop.yourdomain.com

What is a Sub-Domain?

Let us start at the top. To explain what Wildcard SSL certificates do, we need to start by explaining URLs and what a sub-domain even is. There are three main parts to a domain:

Sub-Domain – Sub-Domains are situated before the main domain in the URL. Technically, www. is a sub-domain however most certificates protect both www and non-www domains regardless. Think more like mail.domain.com where mail is the sub-domain.

✅ Primary Domain – The Primary Domain is typically considered the name of the website. For instance, name of this domain is Best-Digital Marketing.co.uk and Google’s website is Google.com.

✅ Top-Level Domain – The Top-Level Domain or TLD is the small portion at the root of a URL usually two or three letters. The Top-Level domain can indicate country of origin or a generic top-level such as – .com or .net or .co.uk

What is - subdomain, primary domain & top level domain

A Little More About Sub-Domains

Sub-Domains can be used for a variety of things. You could host a blog at one, set up a members’ area, an FTP server and mail server and anything you need.

Situated ahead of the Domain name in a URL, subdomains usually look like this:

  • members.bankofamerica.com
  • mail.google.com
  • en.wikipedia.org
  • cwatch.comodo.com

Encrypting your domain and all of its accompanying sub-domains can all be conveniently encrypted with a single Wildcard SSL certificate.

An Asterisk Changes Everything! Wildcards and its cunning use of an asterisk

Before your SSL certificate is issued, you must generate a Certificate Signing Request – CSR. This is like an application for your SSL certificate. The CA will check against the information you provide to validate you and will include that information in your certificate details.

Therefore it is very important you get it right the first time. Where Wildcard SSL differs from traditional SSL is in the Fully Qualified Domain Name field.

You list the exact URL of the website you are encrypting. With Wildcard certificates, you put an asterisk at the sub-domain level you want to encrypt, like this: *.domain.com. Once the certificate issued it automatically secures all sub-domains at the designated level.

An SSL Certificate that Grows with You

The best part of Wildcard SSL is that it is essentially future-proof. If you ever add a sub-domain during your Wildcard SSL certificate’s lifespan, simply re-issue the certificate and re-install it. From that point it will cover the new sub-domain as well.

Add a Sub-Domain – Your business is growing and you are adding new functionality to your website – Excellent.

Re-issue the Wildcard – Simply re-issue your Wildcard SSL certificate and it will cover all your new sub-domains too.

Wildcard SSL is a True Game Changer

Encrypting individual sub-domains would be very expensive should be avoided at all cost. Investing in a Wildcard SSL certificate now saves time and money today and into the future.

Customer trust is EVERYTHING

According to a CA Security Council customer survey:

  • 98% of customers do not even move past browsers’ ‘connection untrusted’ messages.
  • 97% of customers refuse to give credit card details without a padlock.

This shows us how cautious and savvy today’s customers have become. Installing a Wildcard SSL certificate on your site and subdomains immediately assures customers that you are safe to do business with.

Put yourself in your customer’s shoes for a moment and ask yourself which site you would trust more?

Buying a Wildcard Certificate

The first thing you have to do is purchase a Wildcard SSL Certificate. We offer a range of the most reliable wildcard certificates available today starting from £487.53/year. Get in touch now and ask for Wildcard SSL Certificate Choices and we will email you with a selection to choose from.

Filling Out CSR Wildcard

While generating CSR wildcard – you will be asked to enter a series of details. You will need to provide the following details:

  • Common Name Wildcard: This is your domain’s complete name.
  • Organisation Name: This is the legal name of your company.
  • Organisation Unit: This is the specific department within your company that you belong to.
  • Your company’s location: This includes the state/province and country of origin.
  • Company email address.
  • 2048-bit root length.
  • SHA-2 signature algorithm.

The best aspect of a Wildcard SSL Certificate is that it allows you to secure unlimited sub-domains in addition to the primary domain. All you have to do is place an asterisk- * ahead of the domain name when filling out the CSR wildcard.

For instance – if you are registering the domain – mywebsite.com, you will have to enter *.mywebsite.com. This will ensure that you can add any subdomains you want.

This will allow you to add more subdomains in the future during the certificate’s lifecycle.

How to Generate CSR for Wildcard SSL Certificate?

Wildcard SSL Certificate is a required SSL certificate for businesses that carry their business on subdomains and want to secure all of them under a single security solution.

To get a wildcard certificate on the server, you need to first create a CSR and a private key.

Here we will talk about CSR generation for a wildcard for Apache + Mod SSL + OpenSSL as well as the IIS platform.

First – we need to know how to create a private key in OpenSSL.

How to create a Private Key on OpenSSL?

OpenSSL is a free command-line tool for SSL and TLS protocols also used in general as a cryptographic library. OpenSSL should be installed on – /usr/local/ssl/bin path.

Before generating a private key – you should decide the key algorithm, size of a key, a passphrase which is optional. Below is an example of a command used to generate a private key.

openssl genrsa -out private-key.pem 2048

The private key is now generated in your current directory naming private-key.pem where 2048-bit is key size. The generated key format would be PEM.

When you do not keep a passphrase for a private key, you should keep restrictions into server access by admin persons only. A private key with a passphrase will look as follow.

opensslgenrsa -des3 -out .key 2048

However you can use the command below to decode the private key.

openssl rsa -text -in private-key.pem -noout

A decoded private key will look like gibberish with all sorts of characters as shown in the image below.

How to create a Certificate Signing Request – CSR on OpenSSL?

After generating a private key – you should now generate a CSR on OpenSSL.

opensslreq -new -key .key -out .csr

NOTE: To directly access OpenSSL.cnf on windows server you can follow the path below.

opensslreq -new -key .key -config

“c:\Apache Software Foundation\Apache2.2\conf\openssl.cnf”-out .csr

Enter CSR Details:

After applying the OpenSSL command for CSR generation, it is now time to enter CSR details.

  • Common Name: It is a Fully Qualified Domain Name – FQDN you want to add and secure with the certificate. For example – htttps://www.best-digitalmarketing.co.uk
  • Organisation: Here, you need to put your organisation’s legal registered name.
  • Organisation Unit (OU): The department from which the SSL request has been made like HR, IT, Compliance Team, etc.
  • City or Locality: A city or locality where your business is located.
  • State or Province: A state where your business or organisation is incorporated.
  • Country: A country in which your organisation is legally incorporated. It should be a two-letter country code.
