The Basics of the Certificate Command
The Certificate command is a powerful tool used in Cisco’s CCNA Security training to help you secure your network. It allows you to digitally sign documents and provide proof of authenticity for your network. You can create and manage digital certificates on your Cisco devices, and use the Certificate command to do so. In this blog post, we’ll discuss the basics of the Certificate command, how to add, delete and check certificates on your Cisco device, and provide tips on managing certificates.
Deleting a Certificate from Your Cisco Device
If you need to delete a certificate from your Cisco device, the process is relatively simple. To begin, access your Cisco device’s command line interface (CLI) and enter the “no crypto pki certificate chain” command. You will then be prompted to enter the serial number of the certificate you would like to delete. After entering the serial number, the certificate will be removed from your Cisco device. It is important to note that this command will not delete the certificate from your public key infrastructure (PKI).
Checking the Status of a Certificate on Your Cisco Device
You can check the status of any installed certificate on your Cisco device with the “show crypto pki certificate” command. This will give you information about when the certificate was created, its serial number, expiration date, and other important data points. It’s important to make sure that certificates stay up-to-date and not expired, so regularly checking the status of all installed certificates is crucial. Make sure to keep track of all your certificates and set reminders to review their status as necessary. This can help keep your device secure and protect against potential malicious attacks.
