Why do I need an SSL certificate?
Data entered on websites that do not use SSL/TLS is not secure. That means if you accept financial information like credit card numbers, login information like usernames and passwords, or anything that either you or your website's users would want to keep private, you will need an SSL/TLS certificate.
How does the SSL protocol work?Learn more about what an SSL certificate is
The SSL protocol, also sometimes referred to as the TLS protocol, makes it possible to establish a secure, encrypted connection between two computers. With this encrypted connection, visitors to your website can send sensitive information to you—including financial information, usernames, and passwords—without fear of these data getting stolen in transit. SSL certificates work using public key encryption.
With this type of encryption, a website owner generates a private key and a public key algorithmically related to the private key. The private key is kept secret while the public key can be used by a website user to create a "shared secret," a cypher that is unique to a single connection using the SSL protocol which enables the creation of a secure connection.
Should you get an SSL/TLS certificate?
The presence of a lock icon in the address bar of a website is also a key indicator of a secure and trustworthy website. Any website that deals with any kind of sensitive information should definitely get an SSL certificate. Even if your users do not make financial transactions on your website, though, an SSL certificate is a key indicator of your website's legitimacy and trustworthiness.
Website's that use SSL also rank better in search engine results, meaning you can increase traffic to your website just by adding an SSL certificate to your website.
Single address, wildcard, or multi-domain SSL certificates?
In addition to your choice of standard, pro, or business SSL certificates, you can also choose how many domains are covered with a single digital certificate.
Single address SSL certificates
- Also called a single domain SSL certificate, covers one domain name, plus its www subdomain
Wildcard SSL certificates
- Covers one domain name and all subdomains
Multi-domain SSL certificates
- Covers multiple domain names—up to 20 domain names—with one SSL certificate

我該如何安裝 SSL 憑證呢？
To help secure your website or web server and get a URL starting with https, choose an SSL or https certificate from among the SSL certificate options we offer, from Standard to Wildcard to Business extended validation certificates (EV SSL certificate), all at great prices. Each domain registered at Gandi also comes with a free 1-year standard single-address SSL certificate.
For customers with Gandi Web Hosting, we provide a free, standard SSL certificate that can be automatically installed for you.
Otherwise, you are free to use your SSL certificates anywhere you need, by generating your own CSR (certificate signing request), and following the entire procedure on the SSL certificate installation on your website or web server.
Gandi 的 SSL 憑證透過以下方式保護您的網站：
- "https: //" in the website address
- A padlock icon in the address bar
The user can see the details of the https certificate by clicking the padlock icon in the URL address bar, including:
- SSL 憑證簽發機構的名稱
- SSL 憑證的有效期限
我該選擇哪種類型的 SSL 憑證呢？
All SSL certificates we offer are delivered by a Certificate Authority (CA) who guarantees a high level of security, no matter what type of SSL certificate you choose for your website. That being said, here's what each type of https certificate we offer is used for:
- Standard SSL certificate: protects one or several websites. Only the domain name is verified by th Certificate Authority through an online validation process. This type of https certificate can be used on personal sites, content sites, or showcase sites that do not directly handle payments, since it has no warantee on financial transactions. - NB: even if transactions are managed through an external app (e.g. Paypal) you can still use this type SSL certificate.
- Professional SSL certificate: secures one or several websites with a warantee on financial transactions. A Professional SSL certificate offers a higher level of validation. With this type of SSL/TLS (secure sockets layer/transport layer security) or https certificate, the Certificate Authority also validates the organization itself, and therefore can only be purchased by companies that can prove their real, legal existence. As such, this type of SSL certificate is only available for businesses or other legal entities.
- Business SSL certificate (EV): secures one or several websites with a higher warantee regarding financial transactions. It offers the highest degree of security as it requires the Certificate Authority to perform the most extensive verification (known as Extended Validation, or EV) of your identity. This type of SSL/TLS or https certificate is only available for businesses or other legal entities.
- Multi-domain - available on the Standard and Business SSL certificate: The multi-domain SSL certificate option can prove more cost-effective than purchasing and managing more than one single-address https certificate.
- Wildcard - Available for Standard and Pro SSL certificates: Wildcard SSL certificates not only do everything single-address SSL certificates do, they also protect every subdomain for a given domain. It is easier to manage if you have many subdomains to secure with SSL/TLS, and can be quite cost effective.
