To order a code-signing certificate, a certificate request (CSR) must be created. With most certification authorities, you have the option of creating the CSR either in the browser, during the ordering process or on your own server. With Comodo you only have the possibility to create the CSR in your browser. For customers who are less technically experienced, we recommend the creation of the CSR in the browser. After issue, the certificate can be easily exported from the browser using the private key.
