I'm not sure what the argument is here. He basically allows anyone to
use the code in any way they wish.

I do understand that in certain jurisdictions this may accidently incur
liability for certain mis-uses of the code, however, the code licence
allows downstream users to re-licence appropriately as they see fit, so
that's just an abstract debate...

    https://github.com/libtom/libtomcrypt/blob/master/LICENSE


However, I disagree that there is no concept of public domain software.
The author can disclaim their copyright (at least in some
juristictions).  See:

    http://en.wikipedia.org/wiki/Public_domain_software
    http://www.gnu.org/philosophy/categories.html#PublicDomainSoftware



Please don't lets argue this further.  Point is that there exists some
slug of code to compute hashes, that you can do with absolutely whatever
you wish.
