FAQ
SSL/TLS (Secure Sockets Layer and Transport Layer Security) are cryptographic protocols that enable secure internet communication by encrypting data and authenticating connections. They use certificates to establish an encrypted link between a server and a client, ensuring sensitive information like credit card details is transmitted securely.
The SSL/TLS handshake involves the client requesting access to a protected resource, the server sending its SSL certificate with the public key, the client verifying the certificate's validity, generating a symmetric session key encrypted with the server's public key, and both parties using the session key to encrypt and decrypt transmitted data.
SSL/TLS uses two types of encryption keys: asymmetric keys (public and private key pair for identity and session initiation) and symmetric session keys (disposable keys for encrypting/decrypting transmitted data). Asymmetric encryption secures the exchange of symmetric keys.
Look for a padlock icon in your browser, which indicates a secure and authenticated connection. Additionally, the URL should start with 'https://' instead of 'http://', showing that encryption is in use.
To obtain an SSL/TLS certificate, generate a Certificate Signing Request (CSR) on your server, submit it to a trusted Certificate Authority (CA) like SSL.com for verification, and install the issued certificate on your web server to enable HTTPS.
HTTPS secures web traffic by using SSL/TLS to authenticate and encrypt all data between the browser and server. Without HTTPS, data is transmitted unencrypted and vulnerable to interception and tampering by man-in-the-middle attacks.
Using the latest TLS 1.3 protocol ensures optimal security for your website by providing improved performance, stronger encryption, and better resistance to attacks compared to older versions.
SSL/TLS encrypts data in transit, ensuring that sensitive information like credit card details is securely transmitted between the client and server. Certificates authenticate the server's identity, preventing impersonation and man-in-the-middle attacks.
