This is primarily raised by handlers which depend on external libraries (which is currently just :class:`~passlib.hash.bcrypt`).

Many password hash algorithms take proportionately larger amounts of time and/or memory depending on the size of the password provided. This could present a potential denial of service (DOS) situation if a maliciously large password is provided to an application. Because of this, Passlib enforces a maximum size limit, but one which should be *much* larger than any legitimate password. :exc:`!PasswordSizeError` derives from :exc:`!ValueError`. .. note:: Applications wishing to use a different limit should set the ``PASSLIB_MAX_PASSWORD_SIZE`` environmental variable before Passlib is loaded.
