Functionality from this chapter is used for generating passwords and other secrets. All generated output uses strong and safe cryptography, employing a system source of randomness via os.urandom(). Data is always returned as a string suitable for use in URLs.
Passwords are by default 192-bit strong. Other secrets are by default 256-bit strong.
