What Are the Impacts of Not Renewing an SSL Certificate After It Expires? What should I do?

Once the SSL certificate expires, it will cause distrust among major browsers, and the message "insecure" will be prompted when accessing, which has a great impact. It is necessary to find out the cause of expiration and resolve it in a timely manner.

1. The current computer system time is incorrect, all SSL certificates have a date and expiration date, and the computer system time outside the validity time period of the certificate may cause the browser to prompt **SSL certificate has expired or has not yet taken effect.

2. The SSL certificate of ** has indeed expired, and according to the latest international standards for the issuance of SSL certificates, the SSL certificate cannot be issued for more than two years.

3. The site refers to other external links that have deployed SSL certificates, and if the certificate of this external link expires, it will also prompt corresponding errors. The terminal devices that can detect certificate errors in external links are: mobile browser, PC IE6 (IE6 and above are not prompted).

1. The computer system time is incorrect: adjust the time of the computer system to the validity period of the SSL certificate.

If the SSL certificate expires and the certificate is not renewed in a timely manner, the following impacts may occur:

1.When the user accesses, the browser prompts a warning message that the security certificate has expired.

2.After receiving the above warning information, the user may lose trust in the **, or even choose to stop accessing the **, which will have an adverse impact on the company's brand image and user volume.

It is recommended to find a professional CA organization, such as Tianwei Chengxin, to renew the certificate 1-3 months in advance to avoid adverse effects on online business.

At the same time, it is recommended to choose Tianwei Chengxin certificate intelligent management system, and the automatic reminder function of certificate expiration can be submitted for certificate renewal and replacement with one click, so you don't have to be afraid that the certificate will not be updated in time when it expires.

**Not accessible.

After the SSL certificate expires, the Internet project will be interrupted, which will directly affect the operation of services and functions.

After the SSL certificate expires, it cannot be used and needs to be renewed before the certificate expires. Renewal is the process of regenerating a certificate and then installing and replacing it on the server.

1. Determine the expired SSL certificate (domain name).

3. GWORG notifies the verification procedures, and after the verification is completed, the issuance is completed.

Fourth, after getting the new certificate, log in to the server to replace the expired certificate, if it will not be replaced, you can let GWORG complete the replacement of the previous model of this Huixun.

The prompt expires on the SSL certificate.

Renew and replace the certificate that is about to expire. Here's how:

1.Reapply for an SSL certificate. It is recommended to choose a regular platform Tongsui, such as Ruicheng Information to apply for an SSL certificate, if you also purchased it on the same platform before, click Renewal, then the validity period of the new certificate will automatically add the remaining time of the expiring certificate, and you will not lose your effective time.

2.After the application is successful, ** certificate. Taking Ruicheng Information Bureau Xiaobu platform as an example, you can choose the matching certificate format according to your own server type**, and you can use it directly without format conversion.

3.Update the SSL certificate. Deploy the new SSL certificate installation to your server and restart the server.

1. The current computer system time is wrong, all HTTP security certificates have a date and expiration date, and the computer system time is outside the validity time interval of the certificate, which may cause the browser to prompt **SSL security certificate has expired or has not yet taken effect.

2. According to the international standard for the issuance of SSL security certificates, the SSL security certificate can not be issued for more than 39 months.

1. The computer system time is incorrect: adjust the time of the computer system to the validity period of the SSL security certificate.

1. The Mini Program debug has the following invalid certificate information. 2. The browser contains the risk of visiting the following network mu blind fight address prompt certificate. 3. Purchase SSL certificate for free.

4. Select Automatic DNS Verification for Alibaba Cloud Server. 5. After the certificate is installed and issued successfully, the certificate will be issued on the cloud management platform. 6. Double-click the PFX file after decompression, enter the password, and install the certificate.

The following diagram shows that the certificate was successfully installed in the browser. 7. Install the certificate in the computer console as follows: Install the certificate in the computer console as follows.

Will the acca certificate hide the big book expire and bury the trillion bend rent.

Solution to prompt expired or invalid SSL certificate:

2. Computer system time error: Adjust the time of the computer system to the validity period of the HTTPS security certificate.

4. The certificate is not installed correctly: re-install the new certificate, or contact customer service to assist in installing the certificate.

5. Use a self-signed SSL certificate: The security risk of the self-signed certificate is relatively large, so it is recommended to use a browser certificate issued by a CA institution that is trusted and repentant, such as: GlobalSign, Geotrust, Symantec, GDCA, etc.

6. Use certificates with poor versatility: Because the top layer of the certificate trust chain is the CA agency, and these small service providers lack the credibility of the CA organization and are not trusted by the browser. Therefore, it is recommended to choose a CA organization that has passed the certification of the international WebTrust standard and has the ability of international electronic certification services.

SSL certificates.

Expiration has two impacts, one is the loss of Wu Sterling's original data encryption and verification functions, resulting in the data being streaking, and there is a greater security risk; The second is that after the certificate expires, the user accesses, and the browser will pop up a security alarm prompt, resulting in a decrease in the user's trust and conversion rate.

affected. What Do I Do After an SSL Certificate Expires?

First of all, we need to pay attention to the validity period of the SSL certificate in time and renew it before the certificate expiration date as much as possible to avoid affecting the normal use.

If the SSL certificate has expired, don't worry, just contact the joySSL certificate account manager to renew. After the renewal is successful, you will get a new SSL digital certificate.

All you need to do is install a new certificate on the Pants Server or contact JoySSL for technical assistance. Once the installation is successful, you can continue to use the new certificate.

What happens when an SSL certificate expires?

Expired SSL certificates can lead to site downtime, site inaccessibility, significant financial losses, and loss of customer trust. The function of the SSL certificate is to encrypt the transmission of data, and once it expires, it will not only cause downtime, but also risk data leakage. If a data breach happens in a sensitive place, the consequences can be devastating.

How Do I Prevent SSL Certificates from Expiring?

Enterprises have a range of different issues when it comes to certificate management, small and medium-sized businesses may have only one or a few SSL certificates, while some large enterprises with large networks will have many SSL certificates. For companies to have their SSL certificates expire, it's usually the result of regulatory oversight rather than a capability issue.

The Certificate Authority CA periodically sends expiration notices for 90 days before the certificate expires. Businesses need to make sure that these alerts are in the right hands.

WoSign CA provides one-stop SSL certificate service, which not only has the automatic reminder function, but also manually informs and reminds customers to renew or replace the SSL certificate in advance through **, email, etc. It can effectively avoid the occurrence of problems such as certificate expiration caused by customers forgetting to renew the fee. Web Links.

If the SSL certificate expires, it means that the SSL certificate no longer has any protective effect, and it is very likely that private data will be snooped on, stolen from the company, and traffic will be hijacked. Therefore, it is necessary to pay attention to the expiration time of the SSL certificate, and in order to avoid the loss caused by the expiration of the certificate, it is necessary to renew the SSL certificate or apply for another ruler before the SSL certificate expires.

The main thing is**can't be opened, can't be accessed, and prompts an insecurity warning.

Hello, SSL certificate.

It is recommended to use a commercial SSL certificate, and there is a technical ruler to support Lingqing.

and safety and security.

The free certificate has a finger on the risk.

SSL certificate is recommended to use a commercial certificate, in addition to stability, improve the access rate of the network late clearing site, and more importantly, the trust is higher.

In February 2020, Apple announced at a meeting of the CA B Forum that it would no longer trust SSL certificates issued after September 1, 2020, which are valid for more than 398 days. Subsequently, browser vendors such as Google and Firefox also said that they would follow this principle.

There are several main reasons:

1) There is no guarantee that a legitimate** will never become a phishing site;

2) Permanently valid certificates lead to an increasing number of CRLs, which will increase the pressure on the browser's request traffic.

3) The validity period to protect the security of the certificate is a digital certificate based on PKI technology, combined with public key encryption algorithm, symmetric encryption algorithm, hash algorithm and other cryptographic technologies to achieve authentication, encryption, signature and other security functions.

4) If the SSL certificate validity period is not properly set, it will cause great security threats. For example, a self-signed SSL certificate is not subject to international standards and can be set to 10 or even 20 years. Self-signed certificates have not been updated for a long time and are still using the very insecure 1024-bit RSA algorithm and SHA-1 signature algorithm.

The long validity period and fragile encryption algorithm allow hackers to have enough time and computing power to crack the encryption key of the certificate, causing serious consequences. Code Changyun.

5) Shaanxi CA must re-verify the identity information to ensure that the identity verification information is up-to-date and still owns the domain name.

In order to consider the security of the enterprise, the international CA organization reviews the qualification of the enterprise every once in a while, and recommends that the private key be replaced.

When the private key is lost, they should apply to the Certificate Authority (CA) to add their certificate to the Certificate Revocation List (CRL). When a user visits an HTTPS site, the browser will automatically request a revocation list from the CA, and if the certificate provided by the site is pinned in the CRL, the browser will not trust the certificate because the attacker may have the same certificate. Therefore, if the certificate is permanently valid, as more and more private keys are lost, the revocation list will also get larger and larger, because only the ones that are added and not eliminated will not be eliminated, which will not only increase the traffic pressure on the CA, but also increase the traffic of the browser.

Once the validity period is only a few years, the CA can remove those expired certificates from the CRL, because the browser does not trust the expired certificate anyway. "

The effective search period of SSL certificate is shortening year by year, and the reasons why it cannot be valid for a long time are:

From a security point of view, there is no guarantee that a legal** will never become a phishing site. Therefore, CA institutions are required to conduct regular audits and will not issue permanent certificates.

Secondly, setting the validity period of the certificate is very important to protect the security of the certificate! Digital certificates based on PKI technology, combined with public key encryption algorithms, symmetric encryption algorithms, hash algorithms and other cryptographic technologies, are used to achieve security functions such as authentication, encryption, and signature.

Why Do I Need to Set an SSL Certificate Expiration Date? Because the Internet is also very developed and progressive, if you don't set the expiration date of staring at God, there are many people who once they get this certificate, they don't work hard, they don't go in, which will affect the development of the Internet.

Any product, the quality is virtual, the quality is the need to test and follow up, so I think it is necessary to set the validity period of Huai Cruise.

One aspect of setting the validity period of a certificate is to ensure that developers are using certificates with the latest encryption standards to improve security and reduce the number of overlooked old certificates. Because some of the key scum books have the potential to be stolen and attacked with phishing and drive malware. The longer the validity period, the more likely it is to be attacked.

SSL certificate is not valid for a long time, it has an expiration date, we can not ensure that a ** is always safe, especially in the Internet era, the replacement is too fast, ** open and closed to change hands, the company is bought and sold a lot, in this case, the security is easy to be destroyed.

Therefore, in order to ensure the security of deploying SSL certificates, the certificate issuing authority needs to ensure that the information that verifies the identity of the server and organization is as new and accurate as possible, so it sets a validity period for the certificate, and if it wants to continue to deploy the SSL certificate after expiration, Wuyin needs to re-verify the real identity of **.

One aspect of certificate expiration is to ensure that developers use certificates with the latest encryption standards to improve security while reducing the number of overlooked old certificates. Because some certificates have the potential to be stolen, answered and used in phishing and drive malware attacks. The longer the validity period, the more likely it is to be attacked.

When we apply for an SSL certificate, we need to verify the identity of ** to the user. Shortening the validity period of the certificate allows the certificate authority to verify the latest information in a timely manner, and cancel its certificate immediately if it finds non-compliance. This ensures the true identity of the ** and its security.
