Secure Socket Layer (SSL) is a protocol that provides communications security between a client and a server by implementing encrypted data and certificate-based authentication.
SSL is a mature protocol and is supported by most browsers.
SSL uses encryption while transmitting data between two or more parties where the sender encrypts the data and the receiver decrypts the data. This method is known as public key encryption. For the public key encryption to take place, the parties in the loop must present a certificate before transmitting any encrypted data.
To ensure that the certificate used is valid, the SSL usually contacts a trusted third-party server called a Certificate Authority (CA).
HTTPS uses SSL protocols to transmit data. When a message is sent using HTTPS, the message is first encrypted with SSL, sent and received using HTTP, and finally decrypted using SSL.
In comparison to HTTP, HTTPS provides better security through encryption and uses digital certificates.
