Windows: Generate CSR for Code or Driver Signing Certificate

Code Signing Certificates must be purchased from a Certificate Authority (CA) before you can request a Certificate Signing Request (CSR). The CSR contains encoded information on the requestor (you), including name, email address, and public key.

Before you begin, note that not all web browsers support CSR code generation. The browsers used must support a specific function required in the process. It is known that Firefox ESR, IE 11, and Safari (for Mac) support this feature.

  • Step 1. Sign in to the website from which you purchased the code signing certificate.
  • Step 2. In the certificate details, select the option to “Generate Certificate.” You will need to fill out the requested information at the next step.
  • Step 3. Click “Submit” once you’re done. Your web browser will generate the key pair and send it directly to the CA.
  • Step 4. Validate your code signing certificate – this will require you to follow guidelines from your CA. Expect validation to take anywhere between one to five business days.
  • Step 5. Once the validation is complete, the CA will send your code signing certificate to your email address. Download the certificate and export it into your web browser.

Code Signing Certificates are necessary for the publication of software packages on specific platforms – in this case, Windows. You will need a Code Signing Certificate if you wish to develop applications or drivers for this platform
