This article will explain in detail the methods of encrypting information on the website. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Nowadays, Internet shopping is very common, but when you click on a shopping website, have you ever thought about the security of your personal information? Will the password of the account you submitted be stolen? Is the information on this shopping site encrypted?

Website information encryption has become the minimum standard of website security. Encrypting user data to ensure that user data is not leaked is the minimum respect for your customers. So which technology should be used to encrypt website information? The answer is that HTTPS,HTTPS is the best implementation of website information encryption.

What is HTTPS?

HTTPS adds "S" to the HTTP protocol, which means encryption. The ordinary HTTP protocol uses data plaintext transmission, so when users transmit personal private information, there is a risk that the information will be intercepted. The HTTPS protocol will apply the SSL certificate to encrypt the data packet before data transmission, and then transmit the encrypted ciphertext over the network, so that even if the data is intercepted by a third party in the process of transmission, the interceptor will not be able to decipher the ciphertext, and the user data is still secure.

How to build a HTTPS website

To upgrade your website from HTTP to HTTPS, you need to install and deploy a SSL certificate in your Web server. The SSL certificate is issued by the CA institution, and the SSL certificate contains the public key for asymmetric encryption. Before the data transmission, the browser will use the public key in the SSL certificate to encrypt the data asymmetrically.

Application for SSL Certificate

At present, there are many SSL certificate agencies in China, which will assist you to apply for SSL certificates from CA. When applying for a SSL certificate, CA will conduct a strict review of the application company and website to ensure the authenticity of the applicant. SSL certificates are generally divided into three types: EV certificate, OV certificate and DV certificate, and the prices of different types are different. Generally speaking, the EV and OV models are for business users, while the DV models are for individuals and small businesses.

Types of SSL certificates

EV SSL certificate: also known as an extended authenticated SSL certificate, which provides the highest level of trust and authentication. The EV certificate website will not only display the green address bar in the browser, but also highlight the company name, providing a visual guarantee of trust. The EV SSL certificate supports 256bit encryption strength and supports both ECC and RSA algorithms to maximize the security of your website. EV SSL certificate is currently the most high-end server certificate product.

OV SSL certificate: this certificate not only verifies the domain name of the website, but also strictly verifies the identity of all enterprises on the website. Only the enterprise units that have passed the examination can issue certificates to ensure the authenticity and legitimacy of the website. For websites with OV certificates deployed, the "security lock" icon appears in the browser address bar, and the name of the company to which the website belongs can be found in the SSL certificate, which can effectively distinguish phishing sites for users and identify the true identity of the website.

DV SSL certificate: it is a SSL certificate that only validates the domain name of a website. DV certificate can also encrypt and transmit the client browser data, ensuring the data security on the transmission link, but because the DV certificate does not audit the identity of the owner of the website, it is unable to determine the true identity of the website, which is much lower than the EV certificate and OV certificate on the security level.

This is the end of the method of encrypting information on the website. I hope the above content can be of some help to everyone and can learn more knowledge. If you think the article is good, you can share it for more people to see.
