C# How to encrypt file with Threefish algorithm in CBC mode?

Question

C++ / C#

Does anyone have implementations of file encryption algorithm Threefish?
I found only this on the Internet www.scriptscoop.net/t/a49455995a7a/threefish-block ...
https://ru.wikipedia.org/wiki/Threefish
https://github.com/nitrocaster/SkeinFish
file by bytes and encrypt?
and a decoder is desirable.

Answer 1

Look, Bruce Schneier has a list of implementations of this algorithm on his site.
The link at the very bottom.
Here is one such implementation.
There is a Threefish class that inherits from System.Security.Cryptography.SymmetricAlgorithm,
so using it will look pretty much the same as using other descendants of this class.

Answer 2

You can read, encrypt, and decrypt. But it is unlikely that someone will write the corresponding code especially for you.
