Explain SSL and TLS
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols designed to provide secure communication over a computer network. They are commonly used to secure communications between web servers and web browsers, but can also be used in other types of network communications.

SSL was developed by Netscape in the mid-1990s and was later standardized by the Internet Engineering Task Force (IETF) as TLS. TLS is essentially an updated and more secure version of SSL. The terms SSL and TLS are often used interchangeably, but TLS is the more current and recommended standard.

SSL/TLS works by using a combination of public key and symmetric key cryptography. When a client (such as a web browser) connects to a server (such as a web server) that supports SSL/TLS, the two systems perform a "handshake" to establish a secure connection. During the handshake, the client and server agree on the encryption algorithms and keys to use for the session.

Once the secure connection is established, all data transmitted between the client and server is encrypted, ensuring that it cannot be intercepted and read by third parties. SSL/TLS also provides authentication, ensuring that the client is communicating with the correct server and not a malicious entity.

SSL/TLS is widely used to secure online transactions, such as online banking, e-commerce
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are protocols used to encrypt communication between a client (e.g. a web browser) and a server. SSL and TLS provide privacy and data integrity between two communicating applications. They also prevent eavesdroppers from intercepting the communication. SSL and TLS are used to secure websites, web applications, and other internet services.
