How SSL certificates work
SSL certificates use cryptographic keys to establish an encrypted connection. The process involves the use of a public key, which encrypts information sent by users to the server, and a private key, which is used by the server to decrypt this data. When a connection is established between the browser and the server, a “handshake” process takes place, which confirms the authenticity of the SSL certificate before exchanging encrypted data.
The importance of SSL certificates for security
SSL certificates are critical for ensuring security on the Internet. They prevent third parties from intercepting and altering data, ensuring the confidentiality and integrity of the information being transmitted. In addition, SSL certificates influence user trust in a website, as browsers display a lock icon next to the URL to indicate a secure connection.
Types of SSL Certificates
There are various types of SSL certificates, including:
Domain Validated (DV) Certificates: Only verify ownership of the domain name.
Organization Validated (OV) Certificates: Require verification of company information.
Extended Validation (EV) certificates: Provide the highest level of verification and trust, requiring detailed verification of company information.
Issuing and managing SSL certificates
SSL certificates are issued by authorized certification authorities (CAs), which verify the website owner’s information before issuing them. Periodically updating and managing SSL certificates is an important part of maintaining website security and protecting user data.
