How to apply for an SSL security certificate? Detailed process and precautions

at the moment when HTTPS has become the standard of website security, SSL security certificate is the core tool to realize website encrypted transmission and enhance user trust. Although many website managers know its importance, they have little knowledge of the application process and precautions, and it is easy to take detours in the operation. This article will disassemble the whole process of SSL security certificate application from certificate selection, application steps, review points to follow-up maintenance, and sort out key precautions to help various websites successfully complete security upgrades.

, how to choose the appropriate SSL security certificate?

different types of SSL security certificates are applicable to different scenarios, choosing the right certificate is the first step in the application, which directly affects the subsequent security level and audit difficulty.

1, domain name SSL security certificate

this type of SSL security certificate only verifies the ownership of the domain name, the audit process is the fastest, usually a few minutes to complete, suitable for personal blogs, small information websites and other scenes without showing the identity of the enterprise, the cost is low, but only for a single or multiple designated domain name to provide encryption protection.

2, enterprise SSL security certificate

this type of SSL security certificate needs to verify the real identity information of the enterprise, the audit cycle is generally 1-3 working days, suitable for e-commerce platforms, enterprise official websites and other websites that need to show users the formal identity, not only to achieve encrypted transmission, but also to enhance the user's trust in the website, support multi-domain name or wild-card domain name protection.

3, Enhanced SSL Security Certificate

this is the highest level of security SSL security certificate, in addition to verifying the domain name and corporate identity, but also on the enterprise's business qualifications, legal status and other in-depth audit, audit cycle of about 3-7 working days, suitable for financial, payment and other high sensitive industry website, browser address bar will display the name of the enterprise, can maximize user trust.

What should I do before applying for an SSL security certificate?

make preparations in advance, which can greatly shorten the application and review time of SSL security certificates, and avoid the stagnation of the process due to the lack of data.

1, organize basic information

If you apply for a domain name type SSL security certificate, you only need to prepare the domain name information to be bound; if you apply for an enterprise type or enhanced SSL security certificate, you need to prepare a scanned copy of the enterprise business license, a scanned copy of the legal person ID card, a certificate of domain name ownership, and fill in the complete application information form to ensure that all information is consistent and true and effective.

2 Generate a certificate signing request

certificate signing request is the CSR file, which is the core file of the SSL security certificate application, including domain name information, public key and other key content. It can be generated through the server control panel, SSL certificate generation tool, etc. When generating, it is necessary to ensure that the key length is not less than 2048 bits to ensure the encryption strength. At the same time, the corresponding private key file is properly preserved. It needs to be used when deploying the SSL security certificate later.

3. The core operation process of SSL security certificate application?

after completing the preliminary preparation, you can enter the formal application process of SSL security certificate, and follow the steps to ensure the smooth progress of the application.

1, select the certificate service provider to submit the application

give priority to authoritative SSL security certificate service providers trusted by mainstream browsers, such as Symantec, Comodo, Let's Encrypt, etc. Some Cloud as a Service platforms also provide one-stop SSL security certificate application services. Submit the selected certificate type, domain name information, CSR files and related materials on the service provider platform, and submit it for review after confirming that the information is correct.

2, cooperate to complete the authentication

depending on the type of SSL security certificate, the service provider will initiate the corresponding verification process. Domain name certificates usually confirm the ownership of domain names through email verification, DNS resolution verification, etc.; enterprise and enhanced certificates need to cooperate with the completion of manual review of enterprise information, and may receive verification calls from service providers, and need to reply to relevant information in a timely and accurate manner.

3, download and deploy SSL security certificates

is approved, you can download the issued SSL security certificate file from the service provider platform. The certificate format corresponding to different server types is slightly different, so you need to choose the appropriate format. Then log in to the server control panel or through the command line tool, deploy the certificate file and private key file to the server configuration of the corresponding website, and restart the server after completion to make the configuration take effect.

4. Precautions for SSL security certificate application and maintenance?

In addition to following the process, some details directly affect the validity of the SSL security certificate and the security stability of the website, which cannot be ignored.

1, timely renewal of the certificate before expiration

SSL security certificate has a fixed valid period, usually 1-2 years. After expiration, the website will lose encryption protection and the browser will prompt security risks. You need to initiate a renewal application 30-60 days before the certificate expires. The renewal process is similar to the first application. However, some service providers support simplified review, which can quickly complete the renewal and avoid affecting the normal access of the website.

2, ensure that the certificate deployment configuration is correct

deploying SSL security certificates, make sure that HTTP requests in the server configuration automatically jump to HTTPS to avoid users accessing the website through the unencrypted HTTP protocol. At the same time, check whether the certificate chain is complete. If the certificate chain is missing, some old browsers may not recognize the SSL security certificate, resulting in the website showing insecure.

3, regularly check the certificate status

deployment is completed, you can regularly check the validity and encryption strength of the certificate through the security logo of the browser address bar or a professional SSL security certificate detection tool. If there are problems such as certificate revocation and configuration errors, you need to contact the service provider in time to investigate and solve them to ensure that the website is always in a safe and encrypted state.

To sum up, the application of SSL security certificate is a complete process from selection to deployment to maintenance. The core is to select the appropriate certificate type, prepare the data as required to complete the application review, and do a good job in the follow-up renewal and status monitoring. Following the process and precautions sorted out in this article, website managers can efficiently complete the application and configuration of SSL security certificates, build a reliable security barrier for the website, and enhance user trust and the comprehensive competitiveness of the website.
