This article introduces the relevant knowledge of "how to activate and use Namecheap's SSL certificate". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

When Namecheap buys a domain name, you can buy a Comodo PositiveSSL certificate for US $1.99 / year. Although SSL authentication and https encrypted transmission are not necessary for every website, https encrypted data transmission is still necessary for websites that need to protect privacy. PositiveSSL certification is an entry-level product of Comodo. PositiveSSL only verifies the ownership of your domain name, and it is cheap, so it is the cheapest SSL authentication service you can buy.

The SSL certificate does not have to be associated with the domain name purchased by Namecheap. You can also use this ssl certificate on other hosts in the domain name purchased elsewhere, that is, the SSL certificate has nothing to do with where to register the domain name and needs to be associated with the host space.

PositiveSSL has been supported by almost all popular browsers, as long as your PositiveSSL authentication is normal, open your https page with a browser just like a normal http page, the browser will not pop up a security warning.

Positive SSL certificate is an ideal choice because of its simple installation, good technical support and strong browser compatibility. Positive SSL certificates are also an ideal choice for you to learn the installation of SSL certificates before you formally deploy SSL.

Specific steps:

Go to the Namecheap website and click Your SSL Certificates under My Account in the SSL CERTIFICATES menu, as shown in the figure:

Select the SSL certification service you have never used and click the Active link on the right to start applying for activation of your SSL certification.

Next, we will send an authentication signature request file to Namecheap to complete the activation process. Usually, you can choose a signature of Apache+OpenSSL type. If your network server is not Apache or its compatible server, you can choose the authentication type that suits you in the list.

We can learn about Comodo PositiveSSL's CSR generation method by selecting CSR Generation: Using OpenSSL (Apache & mod_ssl, NGINX) from Comodo's official CSR Generation tutorial.

Use the SSH client to connect to your host and use the openSSL with Linux to generate your own CSR file. On the command line, enter:

The code is as follows:

Openssl req-nodes-newkey rsa:2048-keyout myserver.key-out server.csr

Next, you will be asked about your domain name, company, nationality and other information, and you can answer it according to your situation. There is a question that you need to pay special attention to is Common Name. When you answer, you must fill in your domain name (yourdomain.com) and cannot have uppercase letters, otherwise the authentication application will fail, and you need to contact customer service and apply again.

The two files generated, myserver.key is the private key and server.csr is the CSR file.

Be sure to back up the private key. If you lose it, there is no way to recover it. You can use a private key to generate CSR (Certificate Signing Request) by entering the command.

Open the CSR file server.csr, copy the contents of the CSR file into the text input box on the page when you just applied, and click NEXT to proceed to the next step.

Next, you are asked to provide an email that indicates that you are the owner of the domain name, which can be verified by admin@yourdomain.com,root,webmaster, etc. You can choose one of the options provided by him to ensure that your mailbox is valid and your mail server can receive mail normally. After selecting an email, click next, and even if your application is submitted, you need to wait for the authorized company Comodo to verify that you are the domain name owner.

After a few hours, Comodo will send an email to the mailbox you just provided.

Click the here link in your email and enter the CAPTCHA below to submit it to Comodo. Continue to wait and comodo will send you the generated ssl certificate file within a few hours. The email contains an attachment with four files, one of which is your authentication file, and the other important one is the positivessl root certificate. You need to configure them correctly on apache or other web servers to ensure that your ssl network services work properly.
