Hypertext transfer Security protocols ( English :HyperText Transfer Protocol Secure, abbreviation :HTTPS; Often called HTTP over TLS、HTTP over SSL or HTTP Secure) It is a kind of transmission protocol for secure communication through computer network .HTTPS Through HTTP communicate , But use SSL/TLS To encrypt packets .HTTPS The main purpose of the development , Is to provide authentication to the website server , Protect the privacy and integrity of data exchange . This agreement is made by Netscape (Netscape) stay 1994 First proposed in , Then extended to the Internet .

 What is? HTTPS And how to implement HTTPS?

In the history of ,HTTPS Connection is often used for transaction payment on the Internet and the transmission of sensitive information in enterprise information system . stay 2000 From the end of the year to 2010 Beginning of the year ,HTTPS Start to use widely , To ensure that all types of web pages are authentic , Protecting accounts and maintaining user communications , Identity and the privacy of web browsing .

in addition , There's another kind of security Hypertext transfer agreement (S-HTTP) Of HTTP Secure transmission implementation , however HTTPS The wide application of the Internet has become a fact HTTP Secure transmission mode , therefore S-HTTP Not widely supported .

1、 What is? HTTPS?

HTTPS( Hypertext transfer Security protocols ) It's an Internet communication protocol , It can ensure the integrity and confidentiality of the data transferred between the user's computer and the website . Whenever you visit a website , Users want their online experience to be safe and private . therefore , It is recommended that you adopt HTTPS To protect the connection between users and your website ( No matter what's on your website ).

The agreement provides triple critical protection :

  • encryption - Encrypt the data exchanged , To protect it from prying . This means that while the user is browsing the site , No one can “ hear ” The content of the conversation , We can't track their activities or steal their information on multiple web pages .
  • Data integrity - Whether intentional or unintentional , No data can be modified or damaged during data transmission , And it won't be tested .
  • Authentication - Prove that the user can communicate with the target website , This helps protect users from man in the middle attacks and build user trust , And then bring other commercial benefits .

2、 Use powerful A security certificate

Enabling... For the website HTTPS In the process of , You have to get A security certificate . The certificate is issued by the digital certificate authority (CA) Issued by , The agency will take relevant measures , Make sure your website address really belongs to your organization , So as to protect visitors from man in the middle attacks . When setting up certificates , You can choose 2048 A key , To ensure a high level of security . If the key of the certificate you hold (1024 position ) Security is weak , Please upgrade it to 2048 position .

When selecting a site certificate , Please pay attention to the following points :

  • From providing reliable technical support CA Get the certificate at .( Free certificates such as :Let's Encrypt、CloudFlare)
  • Determine the type of certificate required :
  • A single certificate for a single security source ( for example www.guangwei.pro).
  • Multi domain certificate for multiple known security sources ( for example www.guangwei.pro,en.guangwei.pro).
  • Generic certificate for security sources with multiple dynamic subdomains ( for example a.guangwei.pro,b.guangwei.pro).

3、 Use the server side 301 Redirect

Use... On the server side 301 Permanent redirection redirects users and search engines to HTTPS Web pages or resources .

4、 confirm Search engine Can I grab your HTTPS Web pages and index them

  • Please do not pass robots.txt File block grabbing your HTTPS Webpage .
  • Please don't go in your HTTPS The page contains noindex Mark .

If it's Baidu , Please search resources platform in Baidu , Fill in https authentication , Make sure Baidu passes the verification , If it is Google, Please use Google Search Console Of “ URL checking tool ” test Googlebot Can I visit your website .
