What is an SSL Certificate?
SSL Certificates are small data files that digitally bind a cryptographic key to an organization’s details. When installed on a web server, it activates the padlock and the https protocol and allows secure connections from a web server to a browser. Typically, SSL is used to secure credit card transactions, data transfer and logins, and more recently is becoming the norm when securing browsing of social media sites.
SSL (Secure Sockets Layer) and it’s successor TLS (Transport Layer Security) are methods used to secure and encrypt sensitive information like credit cards, usernames, passwords, and other private data sent over the Internet. Website pages secured with SSL and TLS are those branded with the HTTPS in their URL address.
The public and private keys used for SSL are essentially long strings of characters used for encrypting and decrypting data. Data encrypted with the public key can only be decrypted with the private key, and vice versa.
