1. Generate a private key file (ca.key) for the Root CA using the command below. You will be required to enter a pass phrase to be associated with the ca.key file.

   Tip
   Make note of this pass phrase as it will be used multiple times whilst creating the certificate hierarchy.

   
   

   Code Block
   language text
   openssl genrsa -des3 -out ca/ca.key 2048

   
   

2. Generate a self-signed certificate (ca.crt) for the Root CA using the command below. This command generates a new self-signed X.509 certificate named "ca.crt" valid for 3650 days (10 years) using the RSA private key "ca.key". A "ca.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 private key file "ca.key". 

   Code Block
   language text
   openssl req -new -x509 -key ca/ca.key -days 3650 -out ca/ca.crt

   
   

   Note

   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 to CA Common Name (eg, fully qualified host name) [] We set this to the FQDN of the Chariot server Email Address []:
