Step-by-step advice for generating a Wildcard CSR
It is extremely easy to generate CSR wildcard. In fact, the process for generating wildcard CSR is the same as any other CSR, with one key difference. However, before we show you how to generate CSR for wildcard certificate, the following is a brief intro to CSRs in general.
The CSR (Certificate Signing Request) is essentially an application to be issued an SSL certificate. It is an encoded file through which you send the certificate authority your personal information, details about your website, and your public key.
In this article, we will show you how to generate CSR for a wildcard certificate.

Filling Out CSR Wildcard
While generating CSR wildcard, you’ll be asked to enter a series of details. You’ll need to provide the following details:
- Common Name Wildcard: This is your domain’s complete name.
- Organization Name: This is the legal name of your company.
- Organization Unit: This is the specific department within your company that you belong to.
- Your company’s location, including the state/province and country of origin.
- Company email address.
- 2048-bit root length.
- SHA-2 signature algorithm.
The best aspect of a Comodo wildcard 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 example, if you’re registering the domain website.com, you’ll have to enter *.website.com. This will ensure that you can add any subdomains you want. Furthermore, if you want to add more subdomains later during the certificate’s lifecycle, you can do that as well.
How to Generate CSR for Wildcard Certificate?
You can create wildcard certificate CSR using OpenSSL, which is the most commonly used platform for CSR generation. It can be done via the following steps:
Step 1: Access the terminal client in your web server.
Step 2: Type the following: openssl req –new –newkey rsa:2048 –nodes –keyout server.key –out server.csr
Step 3: Enter the domain name, accompanied with the asterisk as illustrated earlier.
Step 4: Enter all of the organization’s details.
Step 5: You’re done! Once you enter the aforementioned details, you would have created a CSR for wildcard.
Once you create the wildcard CSR, be sure to also keep the Private Key in the same machine as the generated CSR.
