SSL certificate is a digital certificate used to encrypt and protect the communication between a web server and a browser. Currently, there are three available SSL certificate verification methods: DNS verification, email verification, and file verification. This article will go into more detail about thisThree kinds of sslCertificatesDomain name verificationwayLet's take a look.
How domain name validation works
Domain name verification for SSL certificates is done by verifying the owner of the domain name. This is done through the verification process by using an SSL Certificate Authority (CA). The CA will send you an email with a link that you will need to click to complete the verification process.
There are three ways to verify a domain name
Email verification
Email verification is the most commonly used domain verification method. When applying for an SSL certificate, the CA will send a verification email to your registered email address. You'll need to click on the link in the email to confirm that you own the domain name. If you don't have access to your registered email address, you can choose to use a different verification method.
DNS validation
DNS verification is a method of verifying the ownership of a domain name by adding a DNS record. When applying for an SSL certificate, the CA will provide you with a unique DNS record that you will need to add to your DNS server. The CA will check if the record exists to confirm that you own the domain name. This method requires some technical knowledge, but it is a very secure verification method.
filesValidation
Document verification is a method of verifying the ownership of a domain name by adding a file on it. When applying for an SSL certificate, the CA will provide you with a unique file that you need to add to the root directory of your **. The CA will check the presence of the file to confirm that you own the domain name. This method is easier than DNS verification, but it still requires some technical knowledge.
Considerations for domain name validation
When applying for an SSL certificate, you need to pay attention to the following:
1.Make sure you have ownership of the domain name.
2.Make sure that you have completed the domain name resolution before applying for an SSL certificate.
3.Make sure you have provided the correct registered email address.
4.Make sure you have the skills to add DNS records or files.
When applying for a certificate, you only need to choose one of them for domain name verification according to your actual situation.
