Can I create a new one if I loose the android (APK) keystore file? I know all data e.g. first name, last name, organization,password,expiration etc. Can I create the same keystore using these data or I should protect the main keystore file in a safe place? 

Is there something like timestamp or hashed or automatically generated data inside the keystore or those data fields that I wrote manually, make the keystore unique and identifiable?
