This is developer tool, hash calculator for hex/dec conversion of various FNV flavours.
It similar to ModdingToolbox (Fogity / formerly known as Hasher).
ModdingToolbox is not opensource project and it has not GitHub repository, and itís not maintained.
MTS_ArtUrlWWW_FNVHasher is opensource, you can use it or as ready-to-use hasher, or as DLL library for using in your projects.
I faced with question of customizing of the https://github.com/KhArtNJava/TS4-STBL-Editor for my needs, so, I was interested in custom C# library and calculator.
I wrote this calculator for my self, but I hope, that it can be useful for another developers. Source code of this program is here - https://github.com/KhArtNJava/FNVHasherDLL .
You will need .NET 4.5 for running of this program.
Thanks for creators of the ModdingToolbox-v1.0.0-win!
