The keystore.jks and truststore.jks files are created by using the following commands (note that this is an example):

1) Create a CA certificate and a private key:

openssl genrsa -des3 -out CA-key.pem 2048
openssl req -new -key CA-key.pem -x509 -days 1000 -out CA-cert.pem

2) Create a keystore with a private key entry that is signed by the CA:

keytool -genkeypair -alias policy_agent -keyalg RSA -keysize 2048 -keystore keystore.jks -validity 3650 -storepass policy_agent
keytool -certreq -alias policy_agent -file request.csr -keystore keystore.jks -ext san=dns:your.domain.com -storepass policy_agent
openssl x509 -req -days 365 -in request.csr -CA CA-cert.pem -CAkey CA-key.pem -CAcreateserial -out ca_signed-cert.pem
keytool -importcert -alias ca_cert -file CA-cert.pem -keystore keystore.jks -trustcacerts -storepass policy_agent
keytool -importcert -alias policy_agent -file ca_signed-cert.pem -keystore keystore.jks -trustcacerts -storepass policy_agent


3) Create a trust store containing the CA cert (to trust all certs signed by the CA):

keytool -genkeypair -alias not_used -keyalg RSA -keysize 2048 -keystore truststore.jks -validity 3650 -storepass policy_agent
keytool -importcert -alias ca_cert -file CA-cert.pem -keystore truststore.jks -trustcacerts -storepass policy_agent


4) Command for listing of the contents of jks files, examples:
keytool -list -v -keystore keystore.jks -storepass policy_agent
keytool -list -v -keystore truststore.jks -storepass policy_agent
