SSL, or Secure Sockets Layer, is an encryption-based Internet security protocol. It was first developed by Netscape in 1995 for the purpose of ensuring privacy, authentication, and data integrity in Internet communications. it's the standard technology for keeping an internet connection secure and safeguarding any sensitive data that is being sent between two systems, preventing criminals from reading and modifying any information transferred, including potential personal details.
The SSL protocol can only be used by websites with an SSL certificate, a digital document that validates a site’s identity. Implementing SSL is essential to boost site security and performance. The two systems can be a server and a client (for example, a shopping website and browser) or server to server (for example, an application with personal identifiable information or with payroll information). here is list of SSL you can consider for your domain.
Buy SSLSSL works by making sure that any data transferred between users and sites, or between two systems remain impossible to read. It uses encryption algorithms to scramble data in transit, preventing hackers from reading it as it is sent over the connection. This information could be anything sensitive or personal which can include credit card numbers and other financial information, names and addresses. SSL certificates protect data transfer using two different encryption techniques: asymmetric and symmetric. Asymmetric encryption uses two separate keys: a public and a private key. The public key is used to encrypt the message, which can only be decrypted by the private key, and vice versa. On the other hand, symmetric encryption uses one shared key, or a pair of keys, to encrypt and decrypt the message. To give a better understanding of how those encryption techniques work, here’s an overview of the process:
