Abstract: Method for repeatable creation of random file enables to create and recreate random files at different places, different times and on different devices. Random files are based on aliases, which can contain any text, including specific information, such as serial number, start date, expiry date, etc. Random files can be used for generations of strong and unique passwords. The strength of the password doesn't depend on alias, so any alias will result in equally strong and unique password. Browser, using the method, would be able to register the user to any resource, by generating a password, using resource's URL as alias, and afterwards automatically log user in using same URL for generating the password again. Users can communicate securely by sending alias in plaintext together with ciphertext encrypted with password. IoT devices can establish master, slave, partner, alien relationship and communicate securely without human introduction.
