To generate a CSR (Certificate Signing Request) for an SSL certificate, follow the steps below, depending on your server or system environment. The CSR is a critical component used to apply for SSL certificates from a Certificate Authority (CA). It includes your public key and identifying information.
🔐 General Steps to Generate a CSR Using OpenSSL (Linux/macOS/Windows with OpenSSL)
-
Install OpenSSL (if not already installed)
-
On Linux/macOS: Typically pre-installed.
-
On Windows: Install from OpenSSL for Windows
-
-
Generate a Private Key
- Create the CSR
-
You will be prompted to enter details:
-
Country Name (e.g., US)
-
State or Province
-
Locality (City)
-
Organization Name
-
Organizational Unit
-
Common Name (e.g., www.yourdomain.com)
-
Email Address
-
-
Submit the CSR to your chosen Certificate Authority to get the SSL certificate.
🖥️ For Windows Server (IIS)
-
Open IIS Manager.
-
In the Connections panel, select the server.
-
Double-click Server Certificates.
-
In the Actions panel, click Create Certificate Request.
-
Enter the requested info in the Distinguished Name Properties:
-
Common Name, Organization, City, etc.
-
-
Choose Cryptographic Service Provider Properties (default is fine).
-
Save the
.req
file which is your CSR. -
Use this CSR when ordering your SSL certificate.
🛠️ CSR Generation Notes
-
Always keep the private key (
yourdomain.key
) secure and never share it. -
The Common Name should match the domain name for which you are requesting the SSL.
-
Most modern SSL providers require a key length of 2048 bits or more.
