Before you can order an SSL certificate, it is recommended that you generate a Certificate Signing Request (CSR) from your server or device. More about Trustify SSL Certificates.
A CSR is an encoded file that provides you with a standardised way to send your public key as well as some information that identifies your company and domain name. When you generate a CSR, most server software asks for the following information: common name (e.g., www.example.com), organisation name and location (country, state/province, city/town), key type (typically RSA), and key size (2048-bit minimum).
If you aren’t sure of the exact company name or location when you generate the CSR, don’t worry; we can change and finalise that information during our review process before we issue the certificate.
Once your CSR is created, you’ll need to copy and paste it into the online order form when you go to purchase your SSL certificate.
