True-License的示範用例

首先要用KeyTool工具來產生私匙庫：

keytool -genkey -alias privatekey -keystore privateKeys.store
然後把私匙庫內的公匙匯出到一個檔案當中：

keytool -export -alias privatekey -file certfile.cer -keystore privateKeys.store
然後再把這個認證檔案匯入到公匙庫：

keytool -import -alias publiccert -file certfile.cer -keystore publicCerts.store
