Generate a private key file (serverCA.key) for the Server CA using the command below. You will be required to enter a pass phrase to be associated with the serverCA.key file.
Tip |

Make note of the passthis pass phrase for the Server CA private key file (serverCA.key) as it will be used again whilst creating the certificate hierarchy. |

openssl genrsa -des3 -out ca/server/serverCA.key 2048 |
Generate a Certificate Signing Request (CSR) for the server CA using the command below. This command generates a new CSR named "serverCA.csr’ using the RSA private key "serverCA.key" and you will be required to enter the pass phrase for the serverCA.key file created in the previous step.

There are a number of fields associated with the creation of the certificate. The required fields are: Country Name (2 letter code) []: State or Province Name (full name) []: Locality Name (eg, city) []: Organization Name (eg, company) []: Organizational Unit Name (eg, section) []: We set this as Server CA Common Name (eg, fully qualified host name) []: We set this as the FQDN of the Chariot server Email Address []: Extra attributes to be sent with the certificate request are: A challenge password []: Any alpha-numeric phrase |
Sign the Server CA with the Root CA using the command below. This command will sign the CSR "serverCA.csr" with the Root CA certificate ‘ca.crt’ and RSA private key ‘ca.key’, creating a new X.509 certificate named ‘serverCA.crt’ valid for 3650 days (10 years). A "serverCA.srl" file will also be created containing the signed certificate's unique serial number. You will be required to enter the pass phrase associated with the Root CA private key file "ca.key".
