SSL stands for Secure Sockets Layer, while TLS stands for Transport Layer Security. TLS is an updated and more secure version of SSL, and it has since replaced SSL as the industry standard protocol for secure communication over the internet. Both SSL and TLS provide a secure and encrypted connection, which helps to protect sensitive data such as login credentials, credit card numbers, and other personal information from being intercepted by unauthorized parties. They use a combination of public and private keys to encrypt data transmitted between the web browser and the web server. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.console.zenlayer.com/glossary/s/ssl-tls.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
