stocker4all/luhn-mod-n
======================

luhn-mod-n is a very simple solution to generate and verify luhn mod n checksums. Possible bases (value for n) are between 2 and 36. Luhn mod 10 is well known from the credit card number checksum. But also in different bases it can be useful to have this checksum functionality.

`luhn-mod-n` is a very simple solution to generate and verify luhn mod n checksums. Possible bases (value for n) are between 2 and 36. Luhn mod 10 is well known from the credit card number checksum. But also in different bases it can be useful to have this checksum functionality.
