The key.jceks needs to be created like this:

keytool -genkey -alias AliasChallengeResponse -keystore key2.jceks -keypass "PassWord" -storepass "PassWord" -storetype JCEKS

Value of CHALLENGE_RESPONSE_SECRET=AliasChallengeResponse

Value of CHALLENGE_RESPONSE_SECRET at CryptoUtil.java is hard coded.
