TLS stands for “Transport Layer Security,” which is a cryptographic protocol that provides secure communication over a network, such as the internet. TLS is used to encrypt data that is transmitted between a client (such as a web browser) and a server (such as a website) to prevent unauthorized access, eavesdropping, and tampering.
TLS is the successor to the older SSL (Secure Sockets Layer) protocol and is commonly used to secure web traffic, email, and other types of network communication. When a client and server communicate using TLS, they establish a secure connection by exchanging cryptographic keys and certificates that are used to encrypt and decrypt the data.
TLS is based on a system of public key cryptography, where each party has a public key and a private key. The public key is used to encrypt data, and the private key is used to decrypt it. This ensures that only the intended recipient can read the data.
TLS is an important security technology that helps protect sensitive data and transactions online. It is widely used in e-commerce, banking, and other industries that require secure communication over the internet.
