Just a simple and fast CRC32C Wrapper with hardware acceleration.
The library overall is licensed under LGPLv3, so you can use it in a propriatary project, as long as you do not change the library itsef!
Software-fallback is taken from: here and Licensed under MIT License and improved by a tiny bit.
The netstandard2.0 variation for .netFramework uses p/invoke for the ANSI-C compatible JustCRC32C.Native library to archive hardware acceleration.
