Generate keystore file:

# Command to create self signed SSL Certificate JKS
keytool -genkey -v -keystore springboot-saml-keystore.jks -alias springboot-saml -keyalg RSA -keysize 2048 -validity 10000

• Password: secret

This enable HTTPS in a Spring Boot Application. This will be using SSL Connection. Add the certificate to Keychain access.
