Citrix NetScaler Certificates – Submit to 3rd Party CA
Submitting the CSR to a 3rd party CA – Comodo Free SSL
We now need to take our CSR created in the previous section and submit that to a 3rd Party Certificate Authority or CA to verify our CSR and provide us with a certificate response we can combine with our CSR and generate the SSL certificate. For the purposes of this demonstration we will use Comodo as our 3rd Party CA, however there are many vendors you can choose from some are free (with restictions) others you must pay for your certificate(s).
| Step | Description | Screenshot |
| 1 | First we need to download our CSR for easy access from the NetScaler
Expand Traffic Management > SSL > SSL Files > CSRs tab Tick the newly created .csr file and click Download |
