Build a personal tech blog from scratch
preface
When the personal blog website is established, it always prompts unsafe links when visiting. Click on the query and find that it is Http, click on other authoritative websites and find that it is Https. Here is an introduction to Http upgrade Https, website deployment SSL certificate. Improve the credibility of their website, at least users click not prompt unsafe. All right, let’s get down to business.
What SSL certificate
SSL certificates are digital certificates similar to electronic copies of driving licenses, passports and business licenses. Also known as SSL server certificates because they are configured on the server. An SSL certificate is issued by a trusted digital certificate authority (CA) after authenticating the identity of the server in compliance with the SSL protocol. It has the functions of authenticating the server and encrypting data transmission. SSL certificates establish a Secure Socket Layer (SSL) between the client browser and the Web server. The SSL protocol is designed and developed by Netscape Communication.
An SSL certificate is deployed on the server to ensure that confidential information entered by users on the browser and queried on the server is encrypted over the transmission link between the user PC and the server and cannot be tampered with or stolen. At the same time, the website visitors to prove the server’s real identity, this real identity is verified by a third party authority. In other words, there are two main functions: data encryption and identity authentication. That is to confirm the authenticity of the website (website identity authentication) and ensure the confidentiality of information transmission.
What is the HTTP
Http Hyper Text Transfer Protocol (Http) is a simple request-response Protocol that usually runs on top of TCP. It specifies what messages the client might send to the server and what responses it might get. The headers of the request and response messages are given in ASCII form; The message content has a MIME-like format. This simple model was a major contributor to the early success of the Web because it made development and deployment very straightforward.
What is the HTTPS
HTTPS (Hyper Text Transfer Protocol over SecureSocket Layer) is an HTTP channel aiming at security. Based on HTTP, HTTPS ensures transmission security through transmission encryption and identity authentication. HTTPS adds SSL to HTTP. The security of HTTPS is based on SSL. Therefore, SSL is required for encrypting details. HTTPS has a different default port from HTTP and an encryption/authentication layer (between HTTP and TCP). This system provides authentication and encrypted communication methods. It is widely used for security-sensitive communications on the World Wide Web, such as transactions and payments.
HTTPS advantage
Advantages of installing SSL certificates for HTTPS encryption:
- 1. Higher encryption level. SSL certificates have higher encryption levels to protect users’ sensitive information. Provides powerful encryption features to protect users’ information from phishing scams and attacks;
- 2. Reduce attacks. Protect websites from attack and reduce the risk of hacking, eavesdropping and man-in-the-middle attacks; Security breaches are a very big problem, and if customer data is compromised as a result, it can have a significant impact on the company. In the long run, adopting preventive measures can save many financial problems and costs.
- 3. Enhance credibility. Can eliminate 360, Firefox, Google and other browsers on the website display “unsafe” impact; And it can create a secure shopping experience – installing SSL certificates is essential if the site involves transactions. Users trust the site with a “secure Connection” flag.
- 4. Enhance your brand reputation by verifying your corporate identity from a trusted certificate Authority (CA) – SSL certificates are required to be authenticated by an authoritative authority and are difficult for phishing sites to apply for.
- 5. Display the green address bar and organization name (only EV SSL certificates have this feature).
Quick SSL Application
This time, I apply for the SSL certificate of Aliyun. Each account can apply for 20, the following will start the introduction based on ali Cloud.
The login
First, log in to Aliyun account and query SSL certificate in the search bar, as shown below.
SSL Certificate management console
Log in to the SSL Certificate Management console and query the existing list.
Create a certificate
Click Create Certificate, a new certificate information will appear.
To apply for the certificate
Click the certificate application, and the following information will appear. Enter the domain name, contact information and location information of the certificate to be applied. All others are default, click Next to verify data information. If the domain name is in Aliyun, you can apply for the certificate in a few minutes.
Download the certificate
After the certificate application is complete, select an appropriate certificate type based on the server type, download the certificate to the local PC, and wait for the certificate installation.
