A .NET implementation of the Ascon cipher suite, which includes Ascon-128, Ascon-128a, Ascon-80pq, Ascon-Hash, Ascon-Xof, Ascon-Hasha, Ascon-Xofa, Ascon-Prf, Ascon-Mac, Ascon-Prfa, Ascon-Maca, and Ascon-PrfShort.
Even more functionality is possible with Ascon, but the number of variants gets a bit silly.
