SSL certificates safeguard and encrypt web server-browser connections. It keeps their data private and prevents hackers from intercepting it. The browser and web server establish an encrypted connection when users visit an SSL-secured website. This encryption protects data from eavesdroppers.

SSL certificates verify website owners’ identities. This authentication ensures that consumers connect to a legitimate website, not a scammer trying to steal their data. SSL certificates protect data during transmission. They prevent intermediaries from altering user-server data.

Browsers show a padlock icon or “HTTPS” in the address bar to identify a secure website with a valid SSL certificate. It boosts user confidence and website trust.

 

Types of SSL Certificates

Different types of SSL certificates include:

  • Domain Validation (DV) Certificate
  • Organization Validation (OV) Certificate
  • Extended Validation (EV) Certificate
  • Wildcard Certificate
  • Multi-Domain (SAN) Certificate

 

Domain Validation (DV) Certificate

This type of certificate verifies that the domain owner has control over the domain. It’s the least extensive form of validation and is often used for basic encryption.

Organization Validation (OV) Certificate

OV certificates verify domain and organization validity. They are trusted and suited for enterprises.

Extended Validation (EV) Certificate

The highest validation is EV certificates. They require extensive organization verification, turning the browser’s address bar green. Financial organizations and e-commerce sites use EV certificates.

Wildcard Certificate

A wildcard certificate covers a primary domain and its subdomains. A wildcard certificate for “example.com” would cover “sub.example.com,” “blog.example.com,” etc.

Multi-Domain (SAN) Certificate

One SAN certificate can secure several domains. It is helpful for multi-domain websites.

How SSL Certificate Works

How SSL Certificate Works

SSL certificates secure browser-web server communication through encryption, authentication, and trust. A step-by-step explanation of SSL certificates:

There is a process to complete a SSL certificate request. Our request has to complete different stages. The complete process is mentioned below.

SSL Request Process

  1. A user types https://www.example.com into their browser.
  2. The browser requests a secure connection from the web server. The server returns its SSL certificate, public key, domain name, and other information.
  3. The browser examines the SSL certificate against a list of trusted CAs kept in the browser or operating system. Companies that provide and verify SSL certificates are CAs.
  4. The browser creates a random symmetric encryption key (session key) after certificate verification. It then encrypts this session key using the server’s SSL certificate public key and transmits it back to the server.
  5. The web server decrypts the browser session key using its secure private key.
  6. The browser and server now share a session key for encryption and decryption. This symmetrically encrypted session key speeds up data transfer.
  7. Any data sent between the browser and the server is now encrypted using the shared session key. This encryption prevents data interceptors from interpreting it.
  8. SSL ensures data integrity and encryption. They construct a hash (a unique string of characters produced from the data) and send it with the data. After receiving the data, the recipient calculates and compares the hash to the one sent. Matching means the data wasn’t altered during transmission.
  9. After the communication session, the user or server can stop it and discard the symmetric session key. This gives each session a unique key.

Let’s move to our main topic. Now, we will discuss top 5 SSL Certificates. I have collected a list for your that is described below.
