TLS

IETF, Fremont, California, United States

Transport Layer Security (TLS) is a cryptographic protocol that provides end-to-end encryption of data transmitted over the Internet, ensuring confidentiality, integrity, and authentication between communicating systems.

It is used in HTTPS to secure communication between browsers and servers, combining asymmetric cryptography for key exchange, symmetric encryption for data transfer, and digital certificates to verify server identity.

Its modern version, TLS 1.3, improves performance and security by reducing the handshake to one round trip, removing outdated algorithms, and requiring modern cipher suites.

According to our data, TLS is the most popular networking technology on the web.
It has 79.6% of the networking market share and is present on 73.1% of all websites.
