This is a [balloon hash](https://crypto.stanford.edu/balloon/) implementation. It is taylored for organism's needs.
The [paper](https://eprint.iacr.org/2016/027.pdf) can be read for more information about the memory hardness properties.
Balloon is provably sequentially sound and is a better alternative to pbkdf2.
It is used as a key derivation function and in places where at a cost to performance one desires memory hardness properties
as a defense mechanism.
