A CSR is a text string created by your server software. You will need this text string to order an SSL Certificate.
If you are unable to generate the CSR on your server yourself, a CSR generator is available on our website at https://secure.europeanssl.eu/en/info/generator. Don't forget to save the PrivateKey locally!
Please note: When using the server platform IIS, it is not possible to use an external CSR generator. In this case, the CSR must be generated directly on the IIS.
