What security feature is provided by both SSL and TLS when used with HTTP?

The feature provided by both SSL (Secure Sockets Layer) and TLS (Transport Layer Security) when used with HTTP is secure and encrypted communication, which is commonly referred to as HTTPS (HyperText Transfer Protocol Secure). This secure protocol ensures that any data transmitted between a user's web browser and a web server is encrypted, making it significantly more difficult for third parties to intercept and read the information being exchanged.

The encryption provided by SSL and TLS protects the confidentiality of the data, such as passwords, credit card numbers, and personal information, safeguarding it from eavesdroppers. This is critical in maintaining secure online transactions and communications, which is why HTTPS is widely used on many websites to enhance security for users.

While data integrity checks and user authentication are also important features of SSL and TLS, the specific designation of secure and encrypted communication directly aligns with the primary purpose and benefit of the HTTPS protocol. Data compression is not a primary focus of SSL/TLS and does not contribute to the security aspect that HTTPS provides.
