I don t know what an https certificate is?

HTTPS certificates are also called SSL certificates.

Explain the reason: **After installing the SSL certificate, using the https encryption protocol to access**, the client browser can be activated between the server and the server"SSL encrypted channel"(SSL protocol) to achieve high-strength two-way encrypted transmission to prevent the transmission data from being leaked or tampered with.

After deploying the globally trusted SSL certificate, the browser has a built-in security mechanism to check the certificate status in real time, and display the authentication information to the user through the browser, so that the user can easily identify the real identity and prevent phishing.

If you use the EV Certificate Explorer to display a green address bar, a green "lock" security sign, strong 256-bit encryption protection, as well as the name of the company and the name of the certificate issuing authority.

If the SSL certificate is deployed, the HTTPS green security lock will be displayed in the browser address bar. It can tell users that they are visiting a safe and trustworthy site, and can operate and transact with confidence, effectively enhancing the company's brand image and credibility.

Through the HTTP vs HTTPS comparison test, it is shown that the new generation of HTTP2 protocol using SSL certificates has a much faster access speed than using the HTTP protocol.

After using the HTTPS protocol, the SSL certificate can authenticate the real identity of the server, thus preventing phishing forgery.

The HTTPS certificate is an SSL certificate, which is a kind of digital certificate and plays a vital role in the security of the company.

1) SSL certificates can encrypt sensitive information so that it cannot be leaked.

The main reason for using SSL certificates is to ensure that sensitive information sent over the Internet can be encrypted and important data is not leaked. This is important because you are passing information between your computer and a server on the Internet, and if it is not encrypted with an SSL certificate, any information you pass can be obtained by third parties, including your credit card number, username and password, and other sensitive information. With SSL certificates, information is guaranteed to be unreadable to everyone, which protects information and data from hackers or ill-intentioned people.

2) SSL certificates provide authentication and prevent phishing**.

In addition to information encryption, SSL certificates provide authentication. This means that you can be sure that your information is being sent to the right server without worrying about someone stealing your information. Effectively prevent a third party from pretending to be yours and deceiving your users, obtaining users' personal information, and causing large or small losses.

The SSL certificate is issued by a trusted CA organization, and the information of the enterprise organization will be rigorously verified when applying for the certificate.

The SSL certificate can be installed in the address bar of the web browser, the green lock icon, the green address bar, and the EV SSL certificate can also display the name of the organization. To ensure that visitors know that their connection is protected and can be used with confidence. This means that visitors will trust you more when they see these prompts.

SSL digital certificates are a type of digital certificates, referred to as SSL certificates. A digital certificate is a digital identity certificate issued by a CA to an end entity. It represents the identity of the end entity, and the SSL certificate represents the endpoint that is the server on which the SSL certificate is deployed (usually corresponding to the domain name or IP address of the server).

SSL certificates are small data files that digitally bind encryption keys to organization details. When installed on a web server, it activates the padlock and HTTPS protocols and allows a secure connection from the web server to the browser. General SSL is used to ensure the security of credit card transactions, data transfers, and logins, and has recently become the standard for ensuring the security of browsing social networks.

Organizations need to deploy the SSL certificate on their web server to initiate a secure session with the browser. Once a secure connection is established, all web communication between the web server and the web browser will be secure.

Once the certificate is successfully installed on the server, HTTP will change to https, where "S" stands for "Secure". Depending on the type of certificate you purchased and the browser you are surfing the web, a padlock or green bar will appear in your browser when you access a ** where an SSL certificate is deployed.

An SSL certificate is a type of digital certificate (digital certificates include: SSL certificate, client certificate, signing certificate, etc.), because the configuration is also called the server SSL certificate on the server. SSL certificate is a digital certificate issued by a trusted digital certificate authority CA (such as WoSign CA) after verifying the identity of the server in accordance with the SSL protocol.

A secure and trustworthy SSL certificate needs to be applied for from a CA (Certificate Authority Authority) and issued only after passing a rigorous review. **How to obtain an SSL certificate, please refer to: web link.

An HTTPS certificate, also known as an SSL certificate, is a type of digital certificate, similar to an electronic copy of a driver's license, passport, and business license. https certificates are used to:

1. Improve the ranking of enterprises

At present, mainstream search engines such as Google and other mainstream search engines have indicated that they will give priority to including ** starting with https, and give ** high weight to effectively improve the ranking of ** keywords. Installing an SSL certificate will enable you to upgrade from HTTP to HTTPS.

2. Encryption of private information

Encrypt the transmitted data, including the user's account password, ID card and other private information, to prevent it from being spied on, stolen and tampered with by hackers. At present, most of the ** will involve the user's private data transmission, and it is necessary to install an SSL certificate.

3. The browser is trusted

If the SSL certificate is not installed, the user will be prompted to be insecure when accessing the enterprise** through Google, Firefox and other browsers, which will inevitably affect the user's access experience, and the installation of the SSL certificate issued by a trusted certificate authority will become a trusted site for mainstream browsers such as Google and Firefox.

4. Prevent traffic hijacking

Ordinary HTTP is very susceptible to cyber attacks, especially traffic hijacking, which will force users and visitors to other websites, resulting in traffic loss. And by installing a trusted SSL certificate, yours can effectively avoid traffic hijacking.

5. Enhance corporate image

Installing an advanced SSL certificate will not only show a green lock and "https", but also display the name of the company, which will greatly increase the trust of users and enhance the image and credibility of the company.

An HTTPS certificate is an SSL certificate, a digital certificate of the SSL Secure Sockets Layer protocol that ensures that all information exchanged between the user's web browser and the web server is encrypted.

Not credibleBrowsers such as Firefox and Internet Explorer will alert you to untrusted security certificatesIf the problem is confirmed, you are using a self-signed SSL certificate. Or is the system ** problem, if you choose to use the system**, change it to automatic.

Self-signed SSL certificates are insecure and not recognized by browsers. If it is a general SSL certificate, check whether the authority that issued the certificate is trusted, that is, whether its root certificate is rooted in the browser. Trusted institutions abroad include GlobalSign, Comodo, Go Daddy, Digicert, and GDPR in China.

HTTPS principle: certificate delivery, verification, data encryption, and decryption process parsing

1. The client initiates an HTTPS request.

The user enters an https** in the browser and connects to port 443 of the server.

2. Server-side configuration.

Servers that use the HTTPS protocol must have a set of digital certificates, which can be made by yourself or applied to an organization. The difference is that the certificate issued by the self-issued needs to be verified by the client before it can continue to be accessed, while the certificate applied for by a trusted company will not pop up a prompt page (startSSL is a good choice, there is a free service for 1 year). This set of certificates is actually a pair of public and private keys.

3. Send a certificate.

This certificate is actually the public key, but it contains a lot of information, such as the issuing authority of the certificate, the expiration time, and so on.

4. Client resolution certificate.

This part of the work is done by the client's TLS, which first verifies whether the public key is valid, such as the issuing authority, expiration time, etc., and if an exception is found, a warning box will pop up indicating that there is a problem with the certificate.

If there is no problem with the certificate, then a random value is generated. This random value is then encrypted with a certificate. As mentioned above, lock the random value with a lock so that you can't see what is locked unless you have a key.

5. Transmit encrypted information.

This part transmits the random value encrypted with the certificate, the purpose is to let the server get this random value, and then the communication between the client and the server can be encrypted and decrypted through this random value.

6. Decrypt information on the server side.

After the server decrypts the content with the private key, it obtains a random value (private key) passed by the client, and then encrypts the content symmetrically through this value. Symmetric encryption is the mixing of information and private keys through some algorithm, so that the private key is not known unless it is known.

Otherwise, the content cannot be obtained, and it happens that the client and the server know the private key, so as long as the encryption algorithm is strong enough and the private key is complex enough, the data is safe enough.

7. Transmission of encrypted information.

This part of the information is encrypted by the server with the private key and can be restored on the client.

8. Client decryption information.

The client uses the previously generated private key to decrypt the information transmitted by the server, so as to obtain the decrypted content. The whole process, even if the third party listens to the data, is helpless.

What is an SSL Certificate?

SSL certificate, also known as server certificate, https certificate, etc., is a kind of digital certificate, its main function is to verify the real identity of the user, and encrypt the information sent and received by the visitor, which can prevent the communication between the user and the user from being intercepted, stolen and tampered with by criminals.

In the past, only some ** that needed to enter sensitive information or passwords would deploy SSL certificates to implement HTTPS encryption. With the development of the Internet, people are becoming more and more aware of the importance of network security, therefore, more and more people choose to deploy SSL certificates to achieve HTTPS encryption regardless of whether they need to enter sensitive information.

Why implement https encryption?

1. HTTPS can protect the integrity of **.

HTTPS is a Secure Socket Layer hypertext transfer protocol, which can ensure that the transmission of information from the user's browser to the server is highly encrypted and will not be stolen and tampered with by third parties. It can also avoid hijacking and inserting ads, etc., to prevent phishing attacks, so as to protect the security and integrity of the company.

2. HTTPS can protect the privacy and security of users.

In HTTP** data is transmitted in clear text, the customer's privacy is very easy to be stolen and leaked, and the deployment of SSL certificate, the data is encrypted and transmitted in HTTPS, which can protect the communication from being intercepted and stolen by third parties, so as to protect user privacy and security. It can also increase user trust and enhance corporate image.

3. Major browsers encourage the use of https

Mainstream browsers such as Google will issue a "non-secure" warning about http, which will greatly affect the user's trust in the **, and even cause the loss of potential customers. Deploying SSL certificates for HTTPS encryption can remove this "insecure" warning, and in the Internet age, earning the trust of customers is crucial.

4. It helps to prioritize the inclusion.

Search engines prefer https encryption, and https ranks better in search engines. Both Google and have made it clear that they will prioritize the inclusion of https**, which will greatly increase the likelihood that customers will find you.

https certificates issued by formal CA organizations (Digicert, Symantec, Geotrust, Comodo, GlobalSign, Thawte, RapidSSL, AlphaSSL, Sectigo, etc.) SSL certificates are trusted and compatible with 99% of browsers on the market.

The premise of trustworthiness requires the CA to authenticate the digital certificate.
