# HashMAC

A flexible [HMAC implementation](https://learn.microsoft.com/en-us/dotnet/api/system.security.cryptography.hmac), allowing to specify any `HashAlgorithm` as input.  

Available as a [![NuGet](https://img.shields.io/nuget/v/HashMAC.svg?style=flat-square)](https://www.nuget.org/packages/HashMAC) package.

# How to use it

## `HashMAC` itself

Short answer: as a [standard HMAC](https://learn.microsoft.com/en-us/dotnet/api/system.security.cryptography.hmac) 😉  

The `HMAC` base class derives itself from `HashAlgorithm`, so except the constructor which takes a secret key, the usage is the same.

## Using it with other hashes

### SHA3

NuGet packages:

- [SHA3](https://www.nuget.org/packages/SHA3): not not maintained anymore

- [SHA3.net](https://www.nuget.org/packages/SHA3.Net): embeds code from Bouncy Castle

Hashes block sizes (required by `HashMAC.Create()`):

| SHA3 size (bits) | Block size (bits) | Block size (bytes) |

|-|-|-|

| 224 | 1152 | 144 |

| 256 | 1088 | 136 |

| 384 | 832 | 104 |

| 512 | 576 | 72 |
