Transport Layer Security (TLS)

Transport Layer Security (TLS) is a cryptographic protocol that provides secure communication over a network, typically the internet. It is an upgraded version of SSL. TLS ensures that data transmitted between two endpoints is encrypted and authenticated, protecting it from eavesdropping, tampering, and forgery.

TLS is widely used to secure communication between web browsers and servers, email servers, virtual private networks (VPNs), and other network services. The protocol encrypts data using symmetric encryption algorithms and authenticates the parties involved using digital certificates.

TLS is essential for ensuring the confidentiality, integrity, and authenticity of data transmitted over a network. It prevents malicious actors from intercepting sensitive information, modifying data in transit, or impersonating legitimate entities.
