This guide explains what the TLS handshake is , how it works, and its importance for network security and ensuring that your messages are private and cannot be intercepted or spoofed.
TLS encryption is a standard cryptographic protocol used to secure network communications, including data you send over the Internet.
Before encrypted communication can occur, trust must be established between the two communicating parties for example, the web server hosting the website and your web browser accessing it.
This is exactly what the TLS handshake does; it establishes israel telegram data a secure channel between the client and server by communicating which TLS versions and cipher suites are supported by both, verifying the server's identity using its public key and SSL certificate, and finally generating session keys that will be used to uniquely encrypt the communication.
TLS vs SSL
TLS is the successor to SSL Secure Sockets Layer, replacing it as the encryption protocol behind S the secure protocol that delivers web pages to your browser and data to your applications. TLS is also used by other software that requires secure network communication.
Cryptographic elements involved
TLS encryption is based on several cryptographic elementsconcepts:
Cipher suite : A cipher suite is an algorithm used to secure an encrypted TLS connection. Each packet contains a key exchange algorithm, a bulk encryption algorithm, and a MAC message authentication code algorithm.
