After you correctly configure the domain name verification information as required, and after the domain name authorization verification is completed and the CA system center has passed the verification, the certificate verification can enter the next state.
Table 2 Domain name verification methods

Ways of identifying	illustrate	Conditions of Use and Restrictions
DNS verification (manual DNS verification)	It means that you need to manually modify the DNS resolution record of the domain name at the DNS resolution service provider of the domain name, and add a TXT or CNAME type record for verification to the resolution record.	You have the authority to modify the DNS resolution settings of the domain name (that is, have the authority to manage the domain name).
Document verification	It means that you manually obtain the certificate verification file from the file verification information, and then create the specified file in the Web directory of the server.	* You have permission to write content to the root directory of the server where the website is located (ie, have server management permissions). * The server opens ports 80 and 443, and supports monitoring HTTP and HTTPS access. Notice Currently, CAs only support authentication requests to ports 80 and 443. If your server does not open ports 80 and 443, do not use file authentication.

5. Click "Organization Management", click "New Organization" to pop up a pop-up box, and fill in the organization management information.

   & The size of the uploaded file is limited to less than 2MB, the format must be png or jpg, and only one file can be uploaded.
   & Failure to upload will prolong the issuance cycle of the certificate. The specific extension time depends on the verification time of the CA agency. In order to avoid prolonging the issuance period of the certificate, it is recommended that you upload the file.
6. After confirming that the information filled in is correct, click "Next" to verify the domain name verification method according to the prompts on the page.
Follow-up：
After submitting the certificate application, you need to verify the domain name authorization. According to the regulations of CA Center, if you apply for an SSL certificate, you must cooperate with the completion of domain name verification to prove your ownership of the domain name you are applying for binding.

Step 3: Domain Name Verification

Overview:
After submitting the certificate application, you need to verify the domain name authorization. According to the regulations of CA Center, if you apply for an SSL certificate, you must cooperate with the completion of domain name verification to prove your ownership of the domain name you are applying for binding.
After you correctly configure the domain name verification information as required, and after the domain name authorization verification is completed and the CA system center has passed the verification, the certificate verification can enter the next state.
The SSL certificate management on this site provides the following 2 methods, which are operated according to the verification method you selected when applying for the certificate:

Ways of identifying	illustrate
DNS verification (manual DNS verification)	Refers to your TXT or CNAME type record.
Document verification	It means that you manually obtain the certificate verification file from the file verification information, and then create the specified file in the Web directory of the server.

Method 1: Manual DNS Verification
According to the specifications of the CA Center, if you apply for an SSL certificate, you must complete domain name verification (also known as verifying domain name ownership) to prove that the domain name to be bound to the certificate to be applied belongs to you.
Manual DNS verification means that you need to manually modify the DNS resolution record of the domain name at the DNS resolution service provider of the domain name, and add a TXT or CNAME type record for verification to the resolution record. The CA agency verifies that the TXT or CNAME record can be parsed, which means that the verification is passed.
If you select manual DNS verification for domain name verification when applying for a certificate, please refer to this chapter for handling.
Precautions
Domain name resolution for manual DNS verification can only be performed on your domain name management platform. The specific resolution method is subject to the resolution method provided by the domain name service provider.
Get verification information
1. Log in to the management center of this site;
2. Select "SSL Certificate > Certificate Management > Click "Certificate Application" to fill in the certificate application information, and select the verification method: DNS verification (recommended).
Click "Next" to get the verification information.

Record Value	On the "Domain Name Verification" page of the certificate, the "record value" returned by this site. It is recommended to click directly to copy and paste the record value
Other settings remain unchanged.

3. Click "OK", the domain name is added and resolved successfully
    When the resolution status is displayed as "Normal", it means that the domain name resolution is added successfully.
    illustrate:
The resolution record can be deleted after the certificate is issued (the same record type host record can only have one record value).

4. If the DNS verification configuration does not take effect, please eliminate and modify according to the following possible reasons until the verification takes effect.
a.log configuration error.
Please check whether the "Host Record" or "Type" are filled in correctly.

b.The effective time of the configuration is too long, and the effective time has not yet expired, so the data cannot be queried.
Please check the effective time (TTL) of this site is 10 minutes by default. If the configured effective time has not expired, please wait until the time expires before verifying.

Method 2: Document Verification
According to the specifications of the CA Center, if you apply for an SSL certificate, you must complete domain name verification (also known as verifying domain name ownership) to prove that the domain name to be bound to the certificate to be applied belongs to you.
File verification means that you manually obtain the certificate verification file from the file verification information, and then create the specified file in the Web directory of the server. The CA agency verifies that the file path can be accessed, which means that the verification is passed.
If you selected file verification as the domain name verification method when applying for a certificate, please refer to this chapter for handling.
Get verification information
①. Log in to the management center of this site;
②. Select "SSL Certificate > Certificate Management > Click "Certificate Application" to fill in the certificate application information, and select the verification method: file verification. Click "Next" to obtain the verification information.
If you have submitted the certificate application materials, click "Domain Name Verification" to obtain verification.
4. On the domain name verification page of the certificate, you can directly view the file verification instructions, as shown in Figure 1.
Figure 1 File Verification

①. Log in to your server, and make sure that the domain name is pointed to the server and the corresponding website is enabled normally.
②. Then create the specified file in the web directory of the server. The file includes the file directory, file name, and file content.
illustrate
The website root directory refers to the folder where you store the website programs on the server. There are roughly the following names: wwwroot, htdocs, public_html, webroot, etc. Please operate according to the actual situation.
Take the root directory of the website as "/www/htdocs" as an example to illustrate:
a. In the website root directory, create a ".well-known/pki-validation" subdirectory.
Here, it is created under the "/www/htdocs" directory, please operate according to the actual situation.
b. In the ".well-known/pki-validation" subdirectory, create a file named "fileauth.txt".
c. Copy the recorded values from the authentication file in the "fileauth.txt" file.
You can use the wget -S URL address command to detect whether there is a jump in the verification URL address.

Step 4: (OV, EV) Organization Verification

When applying for OV and EV type certificates, after the domain name verification is completed, the CA agency will send an organization verification email to the email address you filled in. The CA agency will contact the enterprise/organization according to the verification method you selected to confirm whether the enterprise/organization initiated the certificate order application.
Precautions
* If you purchase a certificate of the same brand again within 13 months and the information has not changed, it will be exempted from organization verification, that is, manual review.
* The status of the certificate is "pending verification".
* The following situations need to complete the organization verification, the certificate can be issued successfully:
Purchase OV and EV certificates for the first time.
It has been more than 13 months since the last certificate purchase.
It has not been more than 13 months since the last purchase of the certificate, but the contact information, company information or certificate brand has changed since the last purchase.
Steps:
1. Please log in to the contact email address you filled in when applying for the certificate.
2. Open the organization verification email from the CA agency.
3. Reply to the email from the CA organization to select the organization verification method.
Organizational verification includes phone, email
If you need to change the organization verification method, please reply directly to the email from the CA Center.
4. Please pay attention to the verification method you choose and cooperate with the CA agency to handle it.
For example, if the organization verification method you choose is phone verification, the CA agency will contact you through the public phone number of the enterprise/organization, please pay attention and deal with it in time.

Step 5: Issue an SSL certificate

The SSL certificate audit time depends on the cooperation between you and the CA. The CA agency will contact you through the email address and phone number reserved by you. Please pay attention to the email address and phone number you reserved when applying for the certificate.
* After confirming that the DNS verification is completed and the verification result is correct, please wait patiently for the DV-type certificate. It will take some time for the CA agency to process it. After the CA agency has passed the review, the certificate will be issued.
* After the OV and EV type certificates are confirmed to be verified by the organization, the CA agency will take some time to process, please wait patiently. After the CA agency has passed the review, the certificate will be issued.
Different SSL certificate types have different audit cycles. In general, the audit cycle descriptions for each certificate type are shown in Table 1.
Table 1 Certificate audit cycle

Certificate type	Review cycle
EV	CA institutions manually review information In the case of correct information, the review cycle is generally 3 to 5 working days
OV	CA institutions manually review information In the case of correct information, the review cycle is generally 1 to 3 working days
DV	No manual review The CA agency issuance system automatically checks the domain name authorization configuration, and can be quickly issued within a few hours if the DNS configuration is correct.

Steps：
After the CA agency has passed the review, the certificate will be issued, and the certificate will take effect immediately after the certificate is issued.
After the certificate is issued, the certificate can be downloaded and deployed on the server for use.
