How long does it take to obtain a certificate?
DV certificates can be provided within minutes after domain ownership is validated. OV and EV certificates usually require 1‑7 business days, depending upon the recognition procedure and the responsiveness of the applicant.

DV just shows domain control; OV validates the company's legal presence; EV performs a comprehensive background check and shows the company's name in the browser's address bar.
Can I get a totally free certificate?
Yes. Let's Encrypt deals free DV certificates, but they do not have warranty, do not support OV/EV, and need automatic renewal by means of ACME.
What is a wildcard certificate?
A wildcard protects an unrestricted variety of subdomains under a single base domain (e.g., *.example.com). It simplifies management but only covers one level of subdomains.
How do I restore an existing certificate?
A lot of CAs send renewal suggestions 30‑60 days before expiration. The buyer can produce a brand-new CSR, submit it, and set up the new certificate. Some providers support auto‑renewal.
