What is https?

Https is an encrypted transmission protocol. After using https, websites can prevent sensitive information from being obtained by third parties. Https encryption protocol = SSL / TLS+http protocol, that is, data transmission encryption can be achieved by adding SSL achievements to the traditional http protocol.

What does it take to upgrade a website from http to https?

Previously mentioned https encryption protocol = SSL / TLS+http protocol, that is to say, the key to upgrading the website from http to https lies in the SSL certificate. After installing the SSL certificate, the website can upgrade from http to https for encrypted transmission to protect the data security of the website.

At first, the role of SSL certificate is only simple in data encryption, with the maturity of technology, more and more additional functions are extended to serve the needs of our website.

III. Benefits of upgrading the website from http to https

(1) identity authentication to reduce customer loss rate

After the enterprise deploys the ssl certificate, it not only encrypts the data of the website, but also verifies the identity of the enterprise to which the website belongs. Further prove that your website is reliable and legal. On the other hand, for websites that do not deploy ssl certificates, some browsers will mark them as insecure, and some users may give up further access when they see the words insecure, resulting in customer loss.

(2) enhance the company's brand image and customer trust.

For websites with advanced EV SSL certificates, the browser will also display the company's enterprise name on the basis of authentication and data encryption, which is a kind of publicity for the company. Further enhance the trust of the website.

(3) help websites improve their search rankings

Google has long shown that https is one of the ranking factors, Baidu has also mentioned before, Baidu will not take the initiative to grab https pages, but Baidu priority to https pages included, priority ranking. From the perspective of relevance, Baidu search engine believes that sites with the same weight, pages using https protocol are more secure, ranking will be given priority.

(4) WeChat Mini Programs, Wechat official account and IOS development must use HTTPS.

Security is one of the most emphasized standards of Mini Program in the development process of Wechat. Wechat stipulates that domain names and protocols that do not meet the conditions in WeChat Mini Programs cannot be requested, that is, WeChat Mini Programs's network request must use the Https agreement, so Mini Program must use the SSL certificate.

What should I pay attention to when applying for a SSL certificate?

1. Select a trusted SSL certificate

Self-signed certificates and some free SSL certificates only have the effect of https, not the role of https, and are not trusted by browsers. It is best to choose international well-known SSL certificates and well-known SSL digital certificate brands such as Symantec, Geotrust, Comodo, Thawte and RapidSSL of Anxin SSL certificate.

2. Select the appropriate SSL certificate

To select an appropriate SSL certificate according to your business needs (as long as the browser's SSL certificate is supported), you need to consider the number of domain names and the type of verification. If there are multiple domain names, you do not need to apply for a SSL certificate for each domain name, you only need to apply for a multi-domain name SSL certificate or wildcard certificate.

3. Choose a secure and reliable SSL certificate

In terms of product features, it is preferred to support SGC forced 128bit encryption of SSL certificates. Only in this way can users be guaranteed to achieve 128bit high strength encryption using various versions of the browser, because 40-bit and 56-bit encryption is no longer secure. Second, if users are using browsers that support 128bit encryption, the site can buy SSL certificates that verify the identity of the entity and display the name of the unit in the certificate, which will be cheaper.
