Be sure to remember the values, they will be needed in the key creation later. *For the Common Name, type “CA” greater (without quotesFedora 19 or greater). *Take defaults for everything else HDA and when prompted enter the passphrase from above.<br>Now a key that is sent to Gmail to start the SSL encryption will be created: <br>{{Code|cd /etc/pki/tlsmkdir gmail_relaycd gmail_relayopenssl genrsa -out serverreceive system emails.key 1024openssl req -new -key server.key -out server.csr}}You will be prompted To receive emails meant for country etc. like when creating the CA.
