Lao Zuo mentioned in several previous articles that Let's Encrypt has applied for a free universal domain name SSL certificate. Indeed, if we need to use the free universal domain name certificate, we can use this provider. At the same time, some netizens told us that we can also apply for the AlphaSSL universal domain name certificate for free. I have heard about the AlphaSSL certificate before. In this article, I plan to apply for the Alphassl universal domain name certificate.
However, some netizens mentioned that the AlphaSSL they may apply for may be revoked, so if we need to use formal projects, we can either use Let's Encrypt certificates or pay certificates.
Note: At present, the application for the AlphaSSL universal domain name certificate through the following method cannot be successful.
First, file for applying for CSR certificate
Application address: https://myssl.com/csr_create.html
Before applying for an AlphaSSL universal domain name certificate, we need to apply for a CSR certificate file before we can apply.

Here we need to apply for the CSR certificate file first, but here we only need to pay attention to the * pan domain name format when filling in the domain name.

Then save the CSR and KEY files for later use.
Second, apply for AlphaSSL universal domain name certificate
Application address: https://en.assl.space/

Fill in the CSR file and email, and click Verify to verify. The verification mailbox message will pop up after reading the related article, but there seems to be a problem here, and the verification cannot be successful.

It can be seen from the relevant articles that it can be applied, but Lao Zuo tested that many platforms providing interfaces could not be applied. Then I saw some netizens mention that the application interface is not available at present.
In conclusion, the article that was intended to be completed ended in failure. If there are other channels to apply for the AlphaSSL universal domain name certificate in the future, it will be reorganized.
