To view certificates for the current user
- Select Run from the Start menu, and then enter certmgr. msc. The Certificate Manager tool for the current user appears.
- To view your certificates, under Certificates - Current User in the left pane, expand the directory for the type of certificate you want to view.
Navigate to Security > Machine Certificates and select a certificate to check the expiry date.
The maximum validity period of TLS/SSL certificates is currently at 825 days (2 years, 3 month, and 5 days). The validity period was sheared from 10 years down to 5 years, and finally to 2 years, owing to the security concerns associated with protracted validity periods.
Android (v.67)
- Click the padlock icon next to the URL.
- From here you can see some more information about the certificate and encrypted connection, including the issuing CA and some of the cipher, protocol, and algorithm information.
Steps to Renew SSL Certificate
- Generate a Certificate Signing Request (CSR)
- Select your SSL certificate.
- Select the validity (1-year or 2-year)
- Fill up all necessary details.
- Click on the Continue button.
- Review your SSL order.
- Make the payment.
- Deploy your SSL certificate on the server.
The RSA private/public key don't have dates in them so they don't expire. RSA Private/Public keys are used for asymmetric cryptography operations. X509 certificates uses a private key to "sign" the certificate so that the corresponding public key can be used to verify the data in the certificate hasn't been modified.
Steps
- Select Configuration, then browse to VPN.
- Expand the Other Elements > Certificates > VPN Certificate Authorities.
- See the Expiration Date column for information about the CA's expiration date.
An SSL certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection. SSL stands for Secure Sockets Layer, a security protocol that creates an encrypted link between a web server and a web browser.
If you allow a certificate to expire, the certificate becomes invalid, and you will no longer be able to run secure transactions on your website. The Certification Authority (CA) will prompt you to renew your SSL certificate prior to the expiration date.
If the certificate is expired, the user's browser has no way to validate the server. That means it can't definitively tell you if the website presenting this certificate is its rightful owner. That's going to cause a browser error that says your connection is not secure. In that case, your website is completely broken.
Answer. If you use S/MIME to sign or encrypt email messages, you should not delete your personal certificate, even after it expires. Doing so would cause you to permanently lose access to those messages.
To help ensure that all certificates are using the latest security standards and in fact controlled by the current certificate owner, we expire them. New certificates are issued using the latest security standards, processes and a re-confirmation of domain control and organization identity.

There may be a signing chain of several certificate authorities, but at the root of the trust chain will be a self-signed certificate, usually with a subject indicating that it is a signing certificate.
Check certificate expiry time
- check the JKS expiry time. check_jks.sh. # to check keystore.jks expiry time. keytool -list -v -keystore keystore.jks -storepass "pass" | grep until.
- check the PKCS#12 expiry time. check_p12.sh. # to check certicate.p12 expiry time.
When Internet Explorer reports the message "The certificate has expired or is not yet valid:" it is very likely caused by the fact that the system date and time have not been setup. See the message here. To resolve the issue, change the date and time settings on the device.
Fix the 'certificate error message' in Internet Explorer
- Open Internet Explorer.
- Click Tools icon. | Internet Options.
- Click the Advanced tab.
- Under "Security", de-select the following: Check for publisher's certificate revocation.
- Click Apply.
- Click Ok.
- Close and relaunch Internet Explorer.
Access the OpenShift Container Platform dashboard, which captures high-level information about the cluster, by navigating to Home → Dashboards → Overview from the OpenShift Container Platform web console.
Logging in to the CLILog in to the CLI using the oc login command and enter the required information when prompted. $ oc login Server [ https://openshift.example.com:6443 The server uses a certificate signed by an unknown authority.
Access to an OpenShift Container Platform cluster using an account with cluster-admin permissions.
- In the Administrator perspective of the web console, navigate to Operators → OperatorHub.
- Use the Filter by keyword box to search for the Web Terminal Operator in the catalog, and then click the Web Terminal tile.
Host health
- To verify that the cluster is up and running, connect to a master instance, and run the following:
- Before you run etcd commands, source the etcd.conf file:
- You can check the basic etcd health status from any master instance with the etcdctl command:
To log in to the registry directly:
- Ensure you are logged in to OpenShift Container Platform as a regular user: $ oc login.
- Log in to the container image registry by using your access token: docker login -u openshift -p $(oc whoami -t) <registry_ip>:<port>
To view the pods in a project:
- Change to the project: $ oc project <project-name>
- Run the following command: $ oc get pods. $ oc get pods -n openshift-console NAME READY STATUS RESTARTS AGE console-698d866b78-bnshf 1/1 Running 2 165m console-698d866b78-m87pm 1/1 Running 2 165m.
You can update, or upgrade, an OpenShift Container Platform cluster within a minor version by using the OpenShift CLI ( oc ). Have access to the cluster as a user with admin privileges. See Using RBAC to define and apply permissions.
200 or 201 response codes indicate a successful request. 400 response codes may be of interest as they indicate a malformed request, which should not occur with most clients. 404 response codes are typically benign requests for a resource that does not exist.
To redeploy a newly generated or custom CA:
- If you want to use a custom CA, set the following variable in your inventory file: # Configure custom ca certificate # NOTE: CA certificate will not be replaced with existing clusters. #
- Run the redeploy-openshift-ca.yml playbook, specifying your inventory file:
Sure, a certificate that has expired a day ago may seem safe to use. You may question what the harm could be. Once a certificate expires, CAs are no longer required to publish the revocation status of that certificate, so you can no longer know if that certificate had been revoked or compromised.
When a root certificate expires, operating systems may flag the certificate as invalid even if you have the new root certificate. You may be able to fix the problem by deleting the expired root certificate.
An end-entity certificate is installed on the server and a new one needs to be installed by the webmaster when it expires. A root certificate is installed on the computer and a new one will likely come in an OS update for when it expires.
