#4 Please add the inverse functions of both algorithms to the library.

[Sebastian]

The description says that both algorithms should be completely invertible. Unfortunately both algorithms are not included in the library. This is a pity, because the algorithm can be used in both directions. Is it possible to add the inverse functions to the library, or is that legally not possible? I would find it a pity if this great algorithm is so acidic and nobody uses it, because only half of it is available.
