Why create a CSR?
A CSR is required whenever you order an SSL certificate. You may create a CSR yourself and submit it in your order or leave this to us.
How does the automatic CSR creation work?
When you submit a CreateSSLCert command without providing a CSR (parameter CSR[0-N]), we will try to create the CSR for you. For this we require:
- private key
- domain
- contact information
Private key
Unless you provide your own private key (parameter PEM[0-N]), we will create a new private key for you and use it to create the CSR. Of course, you will be able to download the private key later as you will need it in order to use the certificate.
Domain
The domain that is supposed to be the Common Name (CN) of the CSR needs to be provided (parameter DOMAIN0). If you provide further domains (DOMAIN1, DOMAIN2, ...), they will be placed into the Subject Alternative Name (SAN) extension of the CSR.
Contact information
If available, we will put the following contact information into the CSR:
- organization name
- street
- city
- state
- country
