Transport Layer Security
Sign in to saveAlso known as TLS, SSL
cryptographic protocols for securing data in transit
Transport Layer Security (TLS) is a set of cryptographic protocols that protect data as it travels across the internet between your device and a website or service. It matters because it prevents others from intercepting or tampering with sensitive information like passwords, financial details, and personal messages while they're being transmitted.

Article
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet. The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
The TLS protocol aims primarily to provide security, including privacy (confidentiality), integrity, and authenticity through the use of cryptography, such as the use of certificates, between two or more communicating computer applications. It runs in the presentation layer and is itself composed of two layers: the TLS record and the TLS handshake protocols.
