Which protocol secures web communications by layering HTTP over SSL/TLS?

Explanation:
HTTPS secures web communications by layering HTTP over SSL/TLS. HTTP carries the web requests and responses, but when run over TLS, the data is encrypted, authenticated, and protected from tampering as it travels between client and server. The TLS handshake establishes a secure session, authenticates the server with a certificate, and negotiates a session key so all HTTP messages are encrypted thereafter. This combination is what makes a secure web connection visible as https:// in the address bar. The other options refer to encryption modes or primitives and do not define a web transport protocol for securing HTTP.
