Skein (in Managed C++ .NET) v1.3 based on SHA3 Competition Submission to US NIST. https://www.schneier.com/academic/skein/

Uses the Threefish encryption algorithm as a primitive in a chained block configuration to build a cryptographically sound hash function (see the original creator’s page for the white paper and related proofs).

This code base was developed over a number of years and originally lived in CodePlex before Microsoft decided to shutter the doors. http://skeinlibmanaged.codeplex.com/ and http://skeinlib.codeplex.com/ LINKS FOR ARCHIVE PURPOSES ONLY! There are some painful lessons in speed and security over the life of this code.

This uses Managed C++ for efficiency and a level of code reliability but is not necessarily optimized for maximum speed. Having said that, when compiled as x64 Release mode, the throughput is adequately speedy for most applications. The resulting DLL can be linked or MSIL merged into .NET code.
