The commands use openssl and keytool from the command line. Install the OpenSSL command line tool and add the OpenSSL PATH in the Windows environment variables if necessary. Keytool is part of the standard java distribution and is located in the bin sub-directory of your jdk installation directory. Chariot will always include a java distribution under the <chariot_install_dir>/lib/runtime/jdk11.0.12_7/bin. Add the keytool PATH in the Windows environment variables if necessary. You will need to restart your command window to pick up this configuration change. |

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.

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). You will be required to enter the pass phrase associated with the Root CA private key file "ca.key".
