How SSL certificates work
- SSL certificates are based on a technology called public key cryptography, which uses a pair of keys (public and private) to encrypt and decrypt data
- When an SSL certificate is installed on an e-commerce website's server, it enables secure communication between the server and the customer's web browser
- The SSL certificate contains information about the website's identity and the public key used for encryption
Public key cryptography
- Public key cryptography involves two keys: a public key and a private key
- The public key is available to everyone and is used to encrypt data sent from the customer's browser to the e-commerce website's server
- The private key is kept secret by the website owner and is used to decrypt the encrypted data received from the customer's browser
- This asymmetric encryption ensures that only the intended recipient (the e-commerce website) can decrypt and read the sensitive information
Certificate authorities (CAs)
- Certificate authorities are trusted third-party organizations that issue SSL certificates to websites after verifying their identity and ownership
- CAs play a crucial role in the SSL ecosystem by validating the legitimacy of websites and ensuring that SSL certificates are issued only to authorized entities
- Examples of well-known CAs include Symantec, Comodo, and Let's Encrypt
Domain validation process
- To obtain an SSL certificate, e-commerce website owners must prove their ownership and control over the domain name they wish to secure
- The typically involves the CA sending a verification email to the domain owner or requiring them to add a specific DNS record
