GOAL


This article explains how to create both Keystore and truststore SSL certificates using Java keytool utility.
JDK must be installed on the system.  The keytool utility is available in JAVA_HOME\bin directory

Three are the steps needed to generate the needed assets to use in our Mule app to have trusted
communications:

.
├── keystore.jks
├── localhost.cer
└── truststore.jks


 

Pasos

 

1. Create the Keystore certificate:

     Keystore is a server-side asset that stores the private keys and the certificates with their public and private keys
  
keytool -v -genkeypair -keyalg RSA -dname "cn=MuleSoft, ou=MuleSoft, o=MuleSoft,L=San Francisco, st=CA, c=US" -ext SAN="DNS:localhost,IP:127.0.0.1" -validity 1825 -alias mykeyalias -keystore keystore.jks -keypass mule123 -storepass mule123
 

2. Export the Certificate to add it into Truststore:  

    Export the certificate so that we can use it in the Truststore.
  
keytool -export -alias mykeyalias -file localhost.cer -keystore keystore.jks
 

3. Create a Trustore certificate:

    Truststore is a client-side asset that serves as a repository of certificates (CA or simple) that the client should trust.
  
keytool -import -v -trustcacerts -alias mykeyalias -file localhost.cer -keystore truststore.jks
