Secure Sockets Layer (SSL) is a cryptographic protocol that provides secure communication between web applications and servers over the Internet. It was created to ensure secure transmission of sensitive information such as credit card numbers, usernames, passwords, and other confidential data. It is most commonly used on websites with online stores and banking websites, but is also found in many other types of web applications.
SSL uses a combination of public key encryption and hashing to ensure data integrity. The protocol uses the public key of the server to encrypt the data and then a digital signature is created which is verified by a trusted third party organization known as a Certificate Authority (CA). This digital signature is sent to the client who can then confirm the data can be trusted as it has been verified by the CA. When establishing an SSL communication session, the server and the client first establish credentials and then the client validates the server’s certificate. The client then generates a session key which is used to encrypt the data transmitted over the network.
SSL is a critical component of secure communication and provides a strong layer of encryption between the web server and its clients. As such, it is important for companies to ensure that their websites are encrypted using SSL to ensure online security and privacy. In addition, many websites use SSL as part of their authentication process to confirm the identity of the user.
SSL is also an essential part of internet security and is required by many companies to prove their online safety measure and standards. It is important for companies to make sure that their systems are up to date and compliant with the latest SSL protocols.
