Instant SSL merchants apply for a 90-day Comodo SSL certificate for free

If our website project is going to be used for a long time, Snail personally recommends choosing a paid SSL certificate and buying it for a longer period of time. This saves the need to replace the certificate every time the contract is renewed, or we use something like Let\\'s Encrypt This is an unlimited renewal certificate, but the cycle of this certificate is 90 days. Although our WEB environment helps automatic renewal by default, sometimes it cannot be automatic, so regular inspections are required.

When Snail was checking the documents this morning, he discovered that foreign Instant SSL merchants also provided free 90-day Comodo SSL certificates. From the introduction, it seems that the contract cannot be renewed, it is only provided for 90 days. It is not suitable for projects that we plan to use in the long term, but it can be applied for projects that require short-term testing, because in some project environments we cannot install certificates like Let\\'s Encrypt with one click, and you can use it directly Third-party certificate installation.

Today is New Year’s Eve. Many students are busy going home, eating and sleeping. Snail is not far from home, so I don’t experience the crowded feeling of Spring Festival every year. I will update this article here, and I will go out for a walk later.

First, free certificate application address

Application address: https://www.instantssl.com/free-ssl-certificate.html

Second, prepare CSR document application

Here we need to prepare CSR documents. There are many online application tools. For example, we can apply at chinassl.

Application address: https://www.chinassl.net/ssltools/generator-csr.html

Apply for KEY files and CSR files. Copy the CSR file and apply for an SSL certificate.

Here we enter the CSR file and select the application system environment.

Third, verify domain name ownership

Choose a method that suits you to verify domain ownership. It can be WHOIS email verification or DNS verification.

Fourth, complete registration information and verification

Here we need to complete the registration information.

Final confirmation of agreement to the terms.

Because I chose email verification, I waited for the email activation code to activate.

Fifth, wait for the certificate after verification

Go to your email to check the verification activation code and activate it to complete the order. In about less than 2 minutes, the certificate file was received by email.

As for the installation of certificates, Snail has introduced it at more length in previous blog posts. We can look at the previous chapters for reference.
