1. A method for generating secrets with a vehicle, the method comprising:
receiving, by a processor of the vehicle, a user selection of at least one action to be used to generate at least one secret;
reading, by the processor of the vehicle, input data, wherein the input data includes action data generated by the vehicle after the at least one action is performed, wherein the at least one action includes performing at least one specified maneuver with the vehicle or inputting a person's control action into a control device of the vehicle;
determining, by the processor of the vehicle, that the action data of the input data indicates that the at least one action was performed; and
generating, by the processor based on rules and responsive to the determination that the at least one action was performed, the at least one secret using the input data by
calculating a unique pseudorandom byte sequence from the action data using the rules; and
using the unique pseudorandom byte sequence as the at least one secret or further processing the unique pseudorandom byte sequence by a function to derive the at least one secret.
