TLS (Transport Layer Security)

Transport Layer Security (TLS) is a cryptographic protocol designed to provide secure communication between web browsers and servers on the internet. It is the successor to Secure Sockets Layer (SSL), which was the original protocol used for this purpose. TLS enhances the security of data transmitted over the internet by providing encryption, which ensures that the data remains private and integral as it travels between the client and the server.

The primary objectives of TLS include:

TLS is used in various applications beyond HTTPS, including email protocols such as SMTP, POP3, and IMAP, as well as other protocols like FTP and VPNs. The widespread adoption of TLS is a critical component in securing online transactions and communications, making it a fundamental technology in the architecture of the internet.
