How To Install eSignature in CMS

hi and welcome to this video my name is Jaime Valencia I'm with the Cisco PDA technical advisors and in this video I'm going to show you how to sign certificates with that internal microsoft CA I hope you enjoy it in this video I'm going to show you how to sign the certificate if you have an internal CA in this case I have my CA on a Microsoft Windows 2012 server and the first thing that we need to do is to go to our C UCM admin page and we need to go to the always administration page once we're in we go to security certificate management and we click find as you can see the certificates that are self signed by the system are going to help this in the description in this case I'm going to use the Tomcat certificate for this scenario I'm going to show you how to do a couple of certificates and then you can do the same with the other certificates if you want we're going to click on the Tomcat certificate that is going to trigger a separate window and we need to click on download dot PE a.m. file and we're going to download this as a PE m file we click on save and we have our file here what we need to do is to change this dot p.m. into a dot CER file I'm going to hit f2 on my keyboard and I'm going to change that de M into dot CER you're going to get a warning that it might become unusable you just need to click on yes and once you do that you can open this file why do we need to do this well because we need to verify some settings that the certificate from CU CM has and you need to emulate those certificates in the new one we go into details and the things that we need to notice are the signature algorithm the signature cash algorithm you need to know the length of the public key in this case it's 2048 bits you need to know the key usage and the enhanced key usage in here we can see that the Tomcat certificate has server authentication and client authentication and for the key usage we have the digital signature can see ferment date and sacrament and certificate sagnik we can close this window and this'll window once you have downloaded the certificate and you have noticed the key usage the enhance key usage then you need to generate a certificate signing request you need to click on generate CSR this will trigger a new window you need to choose the right certificate from this drop-down menu in this case we are going to be doing the Tomcat certificate in the distribution drop-down you can decide if it's going to be just for this server or if it's going to be a multi server you need to make sure...
