Manage SSL Certificates


SSL certificates can be created, discovered, and stored in the centralized repository of Key Manager Plus, and requests can be raised for new certificates or domain addition to an existing certificate. Moreover, you are notified when a certificate is about to expire to help you with their timely renewal.

Use Key Manager Plus to:

  1. Create, discover, or import self-signed or CA issued certificates in the network.
  2. Generate Certificate Signing Request (CSR).
  3. Add requests for new certificates or adding a sub domain to an existing certificate.
  4. Receive notifications when certificates are about to expire.

Self-signed certificates and CSRs can be generated using RSA / DSA / EC key algorithms and SHA signature algorithm as per the details below:

RSA – 1024, 2048, or 4096 bit keys; & SHA-2 (256, 384, or 512 bit) signature

DSA – 512, or 1024 bit keys; & SHA-1 (160 bit) signature

EC – 128, or 256 bit keys; & SHA-2 (256, 384, or 512 bit) signature


1.Discover certificates in your network

You can automatically discover all the certificates available in your network using Key Manager Plus, irrespective of the CA. You can discover the certificates anytime as needed or periodically based on scheduled tasks. The discovery options are quite flexible - you can discover certificates from a single server or multiple servers, and from multiple ports, at one go.

Discover SSL Certificates On Demand

To discover the certificates manually:

Note : The file to be imported must be a text file containing the hostname or IP addresses of individual servers, entered on separate lines. Enter the ports to scan on each server separated by a space, entered on separate lines as illustrated below: 6565
test-username-10 443 7272

If you do not specify any port, SSL certificates using the default port 443 will be discovered.

Click the Discover button.When you click the Discover button, you will be redirected to the Discovery Status page where the status of the current discovery instance is updated.


Discover SSL Certificates Automatically Through Schedules

SSL Certificate discovery can also be scheduled to occur at periodic intervals.

You will get a message confirming addition of a new schedule.

The result of the schedule execution will get updated in the Schedule audit and the Discovery audit tabs.

Track and manage various certificate versions

Sometimes, there occurs situations where you have to use different certificates on different end-servers for the same domain. Under such circumstances, it is necessary for you to track the usage and expiry of all these certificates individually even though they represent a common domain. Monitoring various such certificate versions manually is daunting and error-prone. Key Manager Plus helps you simultaneously track and manage the usage and expiry of various certificate versions from a single window.

To track certificate versions,


Update servers with latest certificate versions

In case of wildcard certificates or single SSL certificate deployed to multiple servers, it is necessary to keep track of servers in which the certificate is deployed and also check if the latest certificate version is in use. Key Manager Plus helps you ensure this.

  1. Navigate to SSL --> Certificates tab
  2. Click the Certificate History icon ( cert-history-icon ) corresponding to the required certificate
  3. A window opens listing the various versions of the certificate. Ensure that the latest version of the certificate is set as the main certificate. If not, click the ( ) icon beside the required version to set that version of certificate as main certificate in the Key Manager Plus repository.
  4. Then again, navigate to SSL --> Certificates tab and click multiple servers icon ( multiple-server ) corresponding to the required certificate.
  5. A window opens listing the servers in which the certificate is deployed along with other information such as IP address, port and certificate validity.
  6. If any of the servers listed has an older / expired version of the certificate, update it with the latest version immediately. Select the server and then click Deploy. Refer to the detailed deployment procedure here.


Also, you can edit details pertaining to a particular certificate or delete irrelevant certificates by selecting the certificate and clicking the More dropdown.

5.Import Certificates

To import the certificates in your network:


6. Delete certificates

You can delete the certificates that are currently not in use. To delete a certificate from Key Manager Plus repository:


7. Certificate Requests

The certificate request workflow is as follows:

Add Certificate Request

To add requests for new certificates or addition of sub-domains to existing certificates, in Key Manager Plus:

Add request

Certificate request status

A certificate request is in either of the following statuses.

When a certificate request is raised, it is automatically elevated to the Open state. The request details can be viewed from the SSL → Certificate request tab, on clicking the domain name of the request.

8. Control expiry notification schedule

You can customize the periodicity of notifications you receive when a certificate is about to expire. To customize the notifications:

Note : You will receive notifications every day after the selected date before the expiry of a certificate. For instance, if a certificate is about to expire in the last week of a month, and you select the Notify if SSL certificates are expiring within 7 days option, then, you will receive a notification that your certificate is about to expire every day of the week before the expiry of the certificate.

9. Track Domain Expiration through WHOIS Lookup

Apart from tracking certificate expiration, Key Manager Plus also helps administrators keep a tab on their expiring domain names through an automated WHOIS look up. The domain expiration details fetched through the lookup are displayed in SSL → Certificates tab against its corresponding SSL certificate. Also, administrators can choose to receive timely email notifications of their expiring domains by configuring it in Settings → Notification tab.

How does the WHOIS lookup work?

Fetching domain expiration details requires a two-stage lookup to WHOIS servers from Key Manager Plus. The first lookup provides the details of the WHOIS server with which the domain was registered by its domain registrar. The second lookup provides information about the domain such as owner details, expiration date etc., All these operations are automated the from Key Manager Plus' interface.

Note : Connection to WHOIS servers requires the use of Port 43. Ensure that port 43 is open in your environment, else the connection would fail and Domain Expiration will be marked Not Available (NA) in the Certificates tab.

10. SSL certificate group

Key Manager Plus allows you to organize SSL certificates into various logical groups and execute actions in bulk on the groups.

Create certificate groups

To create a certificate group,

Note : If you choose to group certificates based on criteria, the conditions will be applied to certificates discovered in the future and they will automatically be added to groups that match the criteria.


Edit certificate groups

To make changes to existing certificate groups,

Note : The certificate group name cannot be modified. However, you can add or modify the list of certificates in a group or the description.


Delete certificate groups

To delete a certificate group,
