mheyman/Isopoh.Cryptography.Blake2bv2.0.0
.NET3.1.NET 6.0.NET 7.0.NET Std2.0
Blake2 hash for sensitive data. Uses Isopoh.Cryptography.SecureArray to assure sensitive data gets wiped from RAM and, if the operating system allows, never gets written to disk.
Get Started
$ dotnet add package Isopoh.Cryptography.Blake2bReadme
BLAKE2B
Argon2 uses Blake2b as a cryptographic building block. This code uses the
C# implementation of Blake2 modified from https://github.com/BLAKE2.
The main modification is that the Blake2 here uses SecureArray<T>. The SecureArray takes a SecureArrayCall
to protect potentially sensitive data. Most other modifications are
strictly cosmetic.
As part of this Blake2b port, an effort was made to speed Blake2b by using techniques like unrolling and using raw buffers in unsafe code. It turns out the CLR optimizes plain code better than unrolled/unsafe code and the original always ran faster. At some point I may try a port to System.Numerics.Vector<T>...
API GENERATION
The API Documentation at https://mheyman.github.io/Isopoh.Cryptography.Argon2 gets generated automatically upon build. This happens via a dummy C# "Doc" project that uses the DocFx NuGet package to produce the API documentation.
