Apply for Multi-Domain and Wildcard SSL Certificates Easily Online with 'Lai Ci Jia Mi'

Enabling SSL certificates is crucial for website security. They encrypt data transmission, preventing hackers from eavesdropping or tampering with information. SSL certificates enhance website credibility, increasing user trust. Search engines favor websites with SSL certificates, improving visibility and traffic. Additionally, SSL certificates protect against phishing and malware threats, ensuring user safety. For websites handling sensitive data, enabling SSL certificates is a necessary measure.

Currently, major vendors like Alibaba Cloud and Tencent Cloud offer free DV SSL certificates, but they have limitations:

• Each account can only apply for 20 free DV SSL certificates.
• They do not support multi-domain or wildcard domains.

If you are looking for a free SSL certificate alternative or supplement, try "Lai Ci Jia Mi".

You can register via email or phone number; real-name authentication is not required.

Apply for SSL Certificate

Apply for SSL certificates in the Lai Ci Jia Mi backend. It supports multiple domains and wildcard domains, addressing some shortcomings of free DV SSL certificates.

The second step is to submit the CSR and select the encryption algorithm. Generally, the default automatic generation for CSR is sufficient. If you have strict security requirements, you can submit your own CSR (not recommended for non-operations). For the algorithm, RSA is generally chosen for better compatibility.

It supports 4 certificate channels (as shown below). The minimum validity period is 3 months, while the maximum is 6 months for Buypass (but Buypass does not support wildcard domains).

Note: Independent channels require points exchange. Points can be obtained by tipping the author, checking in on the mini-program, etc.

After submission, wait a few seconds for the task to be created:

Here, xiaoz chose manual verification and selected DNS verification.

xiaoz used CloudFlare and directly went to the CloudFlare backend to add TXT records as required by Lai Ci Jia Mi.

After adding all records, click "Verify All" and submit the verification.

Next, wait for verification. The independent channel is faster (usually within 5 minutes), while the free channel takes longer (typically 10-30 minutes). This is slower compared to Alibaba Cloud or Tencent Cloud, making it suitable for applications where speed is not critical, or you can directly purchase the independent channel.

Once the application is successful, you can download the SSL certificate for deployment.

Certificate File Description

The downloaded certificate contains multiple files, as shown below.

Typically, if you are using Nginx as the web server, you only need the following two files:

• fullchain.crt: Full certificate, can be renamed to .pem
• private.pem: Private key, can be renamed to .key

Do Not Apply for Too Many Domains at Once

Some users might ask, since "Lai Ci Jia Mi" supports multi-domain SSL certificates, isn't it convenient to submit dozens of domains at once? However, the more domains you submit, the more verification records are generated. If one or more domains fail verification or time out, the entire application will fail.

Therefore, it is recommended to submit a reasonable number of domains per application, ideally controlling it within 5 domains. Submitting too many may actually hinder successful application.

Conclusion

Lai Ci Jia Mi can serve as a supplementary tool for SSL certificates. Its advantages are that it is free and supports multi-domain and wildcard SSL certificates. However, its disadvantages include a short certificate validity period (3-6 months) and a slower application speed.
