What does the TLS protocol mean?Explain in detail how Chrome checks the TLS1.3 version?

TLS (Transport Layer Security) is the successor to SSL (Secure Socket Layer), which is a protocol used for authentication and encryption between two computers on the Internet.

What protocol is SSL/TLS?

SSL (Secure Sockets Layer) is a standard security protocol used to establish an encrypted link between a web server and a browser in online communications.

Explain in detail what protocol is TLS?

Transport Layer Security (TLS) is an upgraded version of the SSL protocol (Secure Sockets Layer). TLS 1.0 is usually marked as SSL 3.1, TLS 1.1 is SSL 3.2, and TLS 1.2 is SSL 3.3.

It is now customary to call the two together SSL/TLS, just know that it is a secure protocol for encryption.

When the web page expects the user to submit confidential data (including personal information, passwords or credit card details), the web page should use encryption, at this time the web server should use the HTTPS protocol to transmit the data, which is actually a combination of HTTP and SSL/TLS;

Similarly, there is SMTPS, which is an encrypted simple mail communication protocol, so that when transmitting mail, it is not transmitted in plain text. Generally, we can choose whether to check SSL/TLS when setting up the mail server, if not checked. Emails are transmitted in clear text.

What does the SSL/TLS protocol do?

HTTP communication that does not use SSL/TLS is unencrypted communication.The dissemination of all information in plain text brings three major risks.

• Eavesdropping: Third parties can learn the content of communications.
• Tampering: Third parties can modify the content of communications.
• Pretending: A third party can impersonate another person to participate in communications.

The SSL/TLS protocol is designed to address these three risks, and it is hoped to achieve

• All information is transmitted encrypted and cannot be eavesdropped by third parties.
• With a verification mechanism, once it is tampered with, both parties in the communication will find it immediately.
• Equipped with identity certificate to prevent identity from being impersonated.

How does Chrome check the TLS1.3 version?

How should we check the TLS version used by the current web page?

We can passGoogle ChromeCheck the Security property to see the TLS version.

The method operation is very simple:

1. Right-click on the current page and select Inspect;
2. Then click the "Security" option to see the TLS version used on this page.

As shown in the image below, you can clearly see that TLS version 1.3 is used ▼

If we can't see the TLS version of the current page, we can click the "M" on the leftain origin", then on the right side, you can see the "Protocol" under the "Connection" property shows the TLS version.

As shown in the image below, it shows TLS 1.3 version▼

How does 360 Extreme Browser check the TLS version used by the current webpage?

Actually, it's easier to check the TLS version with a 360 browser.

We just need to click on the green lock in front of the URL of the current page to see which TLS version is used.

As shown below, use TLS 1.2 version ▼

Why analyze whether the query is TLS 1.3?

In fact, it is because the locomotive collector V7.6 cracked version is used to collect the content of a website.

The problem is here:It was found that the locomotive collector V7.6 cracked version could not collect the https protocol webpage using TLS 1.3.

An error message appears ▼

Error requesting default page current page: Object reference not set to an instance of an object. Void Proc(System.Net.HttpWebRequest)

Solution:Use the loco collector V9 version.

• However, in the computer operating system above WIN10 1909, the locomotive collector V9 cracked version cannot be opened.
• However, some netizens said that when testing the 10 version of the Windows 1809 system, it is possible to open the locomotive collector V9 cracked version.
• Therefore, we can install the 10 version of the Windows 1809 system, and set the Windows 10 system not to be updated automatically.
• Alternatively, use the Windows server directly:Windows Server 2016 Datacenter Edition 64-bit Chinese version.
