The SSL/TLS Handshake is a process that occurs when a user's web browser and a web server establish a secure connection using the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocol. The handshake ensures that data transmitted between the two parties is encrypted and secure.
During the SSL/TLS handshake, the browser and server exchange cryptographic keys, authenticate each other, and negotiate encryption settings. Once the handshake is complete, a secure channel is established for secure data transfer.
The SSL/TLS handshake is a critical step in securing online communications, such as e-commerce transactions and secure logins.
