-alias ${THE_ALIAS} -keyalg RSA -keysize 2048 
-dname "CN=${THE_CN}" -storepass ${THE_PASSWORD}
 
#### Create a Certificate Signing Request
keytool -certreq -keystore keystore.p12 -storetype PKCS12 
-alias ${THE_ALIAS} -sigalg SHA256withRSA -storepass ${THE_PASSWORD}
 
#### Install the downloaded certificate.chain.pem to the keystore
keytool -import -keystore keystore.p12 -alias ${THE_ALIAS} 
-trustcacerts -file the.chain.pem -storepass ${THE_PASSWORD}
 
##### Extract private key
openssl pkcs12 -nocerts -in keystore.p12 -out the_private.key -nodes
 
##### Convert the pem to PKCS12 Keystore
openssl pkcs12 -export -in the.chain.pem -out keystore.p12

Concepts

alias

• unique string to identify the key entry

trustStore vs keyStore

• Keystore is used by a server to store private keys, and truststore is used by third party client to store public keys provided by server to access.
