Transport Layer Security (TLS)

Transport Layer Security (TLS) is a cryptographic protocol used to secure communication between two parties over the Internet. It is the most widely used protocol for securing communications and data transmissions. TLS is an open standard and used in many applications such as web browsers, email clients, instant messaging programs, virtual private networks (VPNs), and internet of things (IoT) devices.

TLS works by creating an encrypted connection between two parties which allows for the secure transmission of data without a third party being able to intercept or modify the transmitted data. The TLS protocol works by using a combination of authentication, encryption, and integrity checks to ensure the secure transmission of the data or communication as it travels back and forth.

The authentication step of the TLS protocol ensures that the two parties involved in the communication are who they say they are. Encryption is then used to prevent the data from being read if it is intercepted by a malicious third party. Finally, the integrity checks are used to ensure that the data has not been modified in transit.

TLS securely authenticates each party involved in the communication, encrypts the transmitted data, and checks the integrity of the communication to ensure it has not been tampered with or modified by a malicious third party. TLS is the most widely used protocol for securely sending communication and data over the internet and is crucial for achieving a secure online experience.
