IOS CA - basic deployment; certificate enrollment and signing process. IOS CA - basic deployment; certificate enrollment and signing process. Purpose of this document. This document is intended as an introduction to how to implement basic deployment of IOS CA and understand the process behind certificate enrollment. What is IOS CA? IOS CA is short for Certificate Authority on IOS. It's a simple, yet very powerful tool to deploy certificates in environments where PKI is needed for security reasons. A typical scenario would be a VPN between two or more hosts and this is why the document is in this section of forums. Please note that for the purpose of this exercise I will focus on manual deployment, rather than using SCEP. SCEP is the more efficient and automatic way to deploy and maintain certificates and will be showcased in section 6. During this exercise I'm using an older version of IOS - 1. T. 3. Configuration. For purpose of this exercise I'm using a very basic configuration. CA ip domain- name cisco.

Please note that the public key of CA decodes to. You can find the public key in . Since both are the same the certificate is self signed. Getting a spoke up to speed. Getting a spoke functional in terms of PKI will require two steps. But also some basic preparation: ntp server 1. PINGER ip domain- name cisco. Following this one should create a container for certificate - a trustpoint. CISCOenrollment terminalsubject- name CN=Pinger. OU=TACrevocation- check crl. Authentication. We need to specify which CA we can trust. We'll use certificate from CA I just created. First of you need to export it from CA itself. To do this you need to see the certificat associated with PKI server and export. CAconfig)#do sh run ? Private key, as opposed to public one, should remain hidden. If you need to transport the RSA keys over insecure medium make sure they are secured with password. Example: I'm securing my RSA keys associated with label . Verification. On PKI client.
