What does the https certificate validation process look like?

The HTTPS certificate is an SSL certificate, and its verification process is as follows:

Check if the SSL certificate has been revoked by the issuing authority

Check the certificate revocation list in the SSL certificate, if it has been revoked, a warning message will be displayed: "The certificate of this organization has been revoked. Security certificate issues may show attempts to trick you or intercept the data you send to the server.

It is recommended that you close this page and do not continue to browse it. ”

Check whether the SSL certificate has expired

Check the expiration date of the SSL certificate, if the certificate has expired, a warning message is displayed: "The security certificate issued by this certificate has expired or has not yet taken effect." Security certificate issues may show attempts to trick you or intercept the data you send to the server.

It is recommended that you close this page and do not continue to browse it. ”

Check whether the domain name of ** is the same as the domain name in the certificate

Check whether the domain name of the ** where the SSL certificate is deployed is the same as the domain name in the certificate, if not, the browser will also display a warning message: "This ** issued a security certificate for another ** address." Security certificate issues may show attempts to trick you or intercept the data you send to the server.

It is recommended that you close this page and do not continue to browse it. ”

Check if this ** is blacklisted for fraud

If it is found that this has been blacklisted for fraud, it will say: "IE has found a reported spoofing." Impersonate someone else and try to trick you into divulging personal or financial information.

It is recommended that you close this page and do not continue to browse it. ”

After the browser has been checked in the above aspects, the security lock symbol will be displayed on the page, and the encrypted page with the SSL certificate deployed will be displayed normally. The above is an introduction to the SSL certificate verification process.

First, verify that the "Trusted Root Certification Authority" in the browser has the authority that issued the SSL certificate.

Second, check if the certificate has been revoked by the certificate authority.

Third, verify whether the SSL certificate of ** has expired.

Fourth, check whether the domain name of the SSL certificate is consistent with the domain name in the certificate.

Fifth, whether the ** has been included in the fraud blacklist.

After confirming the above 5 aspects, the ** can be displayed safely, so it is necessary to deploy an SSL certificate for **security!

The fastest way to SSL certificate is DV verification, only the ownership of the domain can be authenticated, the following are three verification methods for DV certificates, which are roughly divided into 3 types of verification, as long as you choose one of them.

The OV type adds real-name authentication to the enterprise, so real-name verification is conducted.

Summary. Hello dear, I'm glad to answer for you what is the verification process of https certificates?. HTTPS is encrypted and securely transmitted over HTTP via the TLS SSL protocol.

The TLS SSL protocol mainly relies on three algorithms to achieve security functions: asymmetric encryption: symmetric encryption for identity authentication and key negotiation

Encrypt the hash function of the data: verify the integrity of the information, symmetric encryption, asymmetric encryption, and signature, you can refer to this documenthttps using a combination of symmetric encryption and asymmetric encryption. Here's how:

The party that sends the message (the client) uses the server's public key encryption"Symmetric keys", the server uses the private key to decrypt it"Symmetric keys"。This ensures"Symmetric keys"The transmission process is secure, and the data can be encrypted using the "symmetric key".

Hello dear and happy to answer for you. Pro, we can make a small program of python.

The verification process of an HTTPS certificate is generally divided into the following steps: 1. Establish an SSL connection: The browser sends an HTTPS request to the server, and the server returns the certificate.

2. Obtain certificate information: The browser obtains the certificate information returned by the server, including the certificate authority, validity period, public key, etc. 3. Verify the legitimacy of the certificate

The browser verifies that the certificate was issued by a trusted certificate authority and that the certificate has not expired, revoked, and so on. If certificate validation fails, the browser warns the user that the certificate may be at risk. 4. Generate a session key

If the certificate is validated, the browser uses the public key in the certificate to encrypt a random number to generate a session key and send it to the server. 5. Establish a secure connection: The server uses the private key in the certificate to decrypt the random number sent by the browser, and the raw answer is missed into the session key.

Both the browser and the server have a session key, which is then encrypted and decrypted to establish a secure connection. In general, the HTTPS certificate verification process is designed to ensure the security of the identities and communication content of both parties, as well as to prevent network security issues such as man-in-the-middle attacks.

How to apply for an HTTPS security certificate and how to apply for an HTTPS security certificate.

1) How to choose the right https security certificate? You can see the concept diagram of choosing an https security certificate

2) Once you have successfully purchased a suitable https security certificate, proceed with the following steps:

1. Generate a CSR for the certificate request file

The first step for users to apply for an HTTPS certificate is to generate a CSR certificate request file, and the system will generate two keys, one is the public key is the CSR file, and the other is the private key, which is stored on the server. To generate a CSR file, the webmaster can refer to the documentation of the webserver, generally apache, etc., use the openssl command line to generate key+csr2 files, tomcat, jboss, resin, etc. use keytool to generate jks and csr files, and iis creates a pending request and a csr file through the wizard.

2. Submit the CSR to the CA for certification.

CA agencies generally have 2 types of certified dust distribution methods:

Domain name authentication, generally through the administrator's mailbox authentication method, this way of authentication is fast, but the issued certificate does not have the name of the enterprise, only the ** domain name is displayed, that is, Pei Tan Zen often says that the domain name HTTPS certificate. The popular free HTTPS certificate is also a domain name HTTPS certificate.

For enterprise document certification, the business license of the enterprise needs to be provided. It generally takes 1-5 working days to apply for CA certification for a foreign https certificate.

At the same time, the certificate of the above two ways is called.

EVSSL certificate.

The EVSSL certificate can turn the browser address bar green, so the certification is also the most stringent. EVSSL certificates are mostly used in fields with high requirements for information security protection, such as finance, e-commerce, and **. 3. Obtain the HTTPS certificate and install it.

After receiving the HTTPS certificate issued by the CA, deploy the HTTPS certificate to the server, and copy the key+cer file directly to the file in general, and then modify the file. For example, Tomcat needs to import the certificate CER file issued by the CA into the JKS file, copy it to the server, and then modify it. IIS needs to handle pending requests to import the CER file.

3) Install SSL certificate;

There are 3 main steps to apply for an HTTPS certificate (i.e., SSL certificate):

1. Make CSR files.

CSR is a Certificate Secure Request document created by the applicant. During the production process, the system will generate two keys, one is the public key is the CSR file, and the other is the private key, which is stored on the server. To make a CSR file, the applicant can refer to the documentation of the web server, generally Apache, etc., use the OpenSSL command line to generate key+csr2 files, tomcat, jboss, resin, etc. use keytool to generate jks and csr files, and iis creates a pending request and a csr file through the wizard.

2. CA certification.

Submit the CSR to the CA, and the CA generally has two ways to certify:

1) Domain name authentication: Generally, through the way of administrator email authentication, this method of authentication is fast, but there is no enterprise name in the issued certificate;

2) Enterprise document certification: The business license of the enterprise needs to be provided.

There are also certificates that need to be authenticated in the above two ways at the same time, called EV certificates, which can be used to make the address bar of browsers above IE7 turn green, so the certification is also the most stringent.

3. Certificate installation.

After receiving the CA certificate, you can deploy the certificate to the Shangshan server, and the general Apache file directly copies key+cer to the file, and then modifies the file; Tomcat, etc., you need to import the certificate CER file issued by CA into the JKS file, copy it to the server, rent it and then modify it; IIS needs to handle pending requests to import the CER file.

1) Ensure the security of users' privacy information.

SSL certificates allow you to encrypt transmission, which can prevent user privacy information such as usernames, passwords, transaction records, and residence information from being stolen and tampered with. For example, if you install an SSL certificate on e-commerce, you can effectively protect the security of the username and password you submit when you log in to e-commerce** to pay.

2) Help users identify phishing**.

The SSL certificate can authenticate the real identity of the server, which can effectively distinguish between phishing and official. After deploying a globally trusted SSL certificate, such as WoSign 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.

3) Conducive to SEO optimization.

Because the SSL certificate deployed is more credible and more secure than the one without the SSL certificate, it can effectively protect the interests of users from being infringed. Therefore, search engines such as Google, from the perspective of ensuring the security of user information, are vigorously advocating the deployment of SSL certificates to achieve HTTPS encrypted access. In terms of search, display, and sorting, SSL certificates are also deployed** preferential treatment.

4) Enhance the company's brand image and credibility.

Deploy SSL certificates to set yours apart from the rest. If the SSL certificate is deployed, the HTTPS green security lock will be displayed in the browser address bar, and if the EV SSL certificate is deployed, the green address bar and organization name will be displayed. 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 information and credibility.

The role of the https certificate is the benefit, which is manifested in the following ways:

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

2. Privacy information encryption encrypts 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. If the SSL certificate is not installed in the browser, 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 the trusted certificate authority will become a trusted site of mainstream browsers such as Google and Firefox.

4. Prevent traffic hijacking Ordinary http is very vulnerable to network 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 the corporate image and install the advanced SSL certificate, which will not only show the green lock and "https", but also display the enterprise name, which will greatly increase the trust of users and enhance the image and credibility of the enterprise.
