When you open a website, do you notice that they start with the letters HTTP or HTTPS? What is the difference between the two?
What is HTTP?
The full name of HTTP is Hypertext Transfer Protocol. Simply put, HTTP is a communication protocol. It allows the transmission of hypermedia documents, such as HTML.
In other words, HTTP forms the basis for any form of data exchange through the World Wide Web. This is why it is the key part of the URL address. Without HTTP, you will not be able to browse web pages, send or receive data over the Internet.
Advantages of HTTP:
- Flexible and expandable.Use HTTP to send and receive data and browse the Internet easily
- Stateless, convenient to implement clusters, and avoid interactions between various requests and group postings.
- fast reaction. Unless your Internet connection is unstable or slow, communication via HTTP is instant.
shortcoming Or HTTP:
- Clear text transmission, data visible, easy to analyze and monitor
- If the communication identity is not verified, hackers can easily disguise themselves.
- Unable to determine the integrity of the transmitted content.
What is HTTPS?
HTTPS On behalf of the hypertext transfer protocol security. It is a network communication protocol that transmits encrypted HTTP data through a secure connection. HTTPS uses the SSL/TLS protocol to encrypt data sent or received on the Internet.
In other words, there is not much difference between HTTP and HTTPS in function, but the latter has security encryption. HTTPS is a secure version of HTTP, so it is suitable for the secure transmission of sensitive data via the Web, such as login credentials and credit card numbers.
Advantages of HTTPS:
- Authentication: HTTPS authenticates the SSL certificate information to confirm the true identity of the website, so that users can identify the correct website information
- Data encryption and transmission: HTTPS uses SSL encryption layer and secure sockets to encrypt and decrypt data to ensure data security during transmission.
- Data integrity: Using the HTTPS protocol can prevent data content from being stolen and tampered with during transmission, allowing you to obtain true and reliable data.
- Improve SEO: Using HTTPS does not affect the inclusion, but you can also get better website rankings.
shortcoming Or HTTPS:
- The cost of SSL certificate is high, and the deployment, update and maintenance of SSL certificate on the server are cumbersome
- Due to multiple handshake (protocol authentication), HTTPS will slow down website access
- HTTPS involves a security algorithm that consumes CPU resources, which means that the site requires a higher server configuration.
Upgrade HTTP to HTTPS
After determining the advantages and disadvantages of HTTP and HTTPS, it is recommended to upgrade HTTP to the latter. In addition, Google is working hard to ensure that everyone uses HTTPS to enhance everyone’s online security. This is a detailed guide on how to migrate from HTTP to HTTPS.
Step 1: Purchase an SSL certificate
The first step in upgrading from HTTP to HTTPS is to purchase an SSL certificate. After installing the certificate, it will activate the HTTPS protocol, allowing a secure connection between the server and the web browser. You also need to choose the correct certificate based on your business needs.
The available options include domain verification certificates, enterprise/organization verification certificates, and extended verification certificates. It is best to purchase an SSL certificate from your hosting company so you can ensure that it is valid and flawless.
Step 2: Install SSL certificate
Now that you have an SSL certificate, the next step is to install it on your web server. If you buy an SSL certificate from a hosting company, the process will be easier because they will install it on your behalf.
Step 3: Test your certificate
After installing the SSL certificate on the web server, you need to check whether it is working properly.You can use online tools from reputable sources, such as SSL lab server test.
You also need to check whether internal links have been migrated from HTTP to HTTPS before going online to ensure that there are no migration errors.
Step 4: Set up a 301 redirect
After installing the SSL certificate, you need to set up a 301 redirect so that you can redirect all server traffic to the new secure HTTPS. Once you do this, the visitor/customer who bookmarked it under HTTP will be routed to the correct secure URL.
You only visit an HTTPS website or have upgraded from HTTP to HTTPS does not guarantee your online security. If you do not make extra efforts to enhance your online security and privacy, you may still become a victim of online attacks and your data content may be stolen.
Therefore, I recommend that you always visit a secure website to ensure your own safety. If necessary, use security tools such as VPN or proxy to protect your privacy and security while browsing the Internet.
