"""Collection of the ISO 7064 algorithms.

This package provides a number of modules for calculation and verification
of numbers using one of the ISO 7064 algorithms.

Note that these functions were not implemented using the ISO text itself
because the text is not available for free. These functions were
implemented based on information on the algorithms found online and some
reverse engineering. If anyone can provide a legal copy of the ISO/IEC
7064 standard these functions can be validated and perhaps improved.
