Masterly.Hash.Integrity.Blake3

Masterly.Hash: password hashing you can't get wrong.

Adds BLAKE3 to Masterly.Hash.Integrity in two modes: plain (blake3:<hex>) and keyed (blake3-keyed:<keyId>:<hex>). You can use it anywhere that package accepts a ContentHashAlgorithm: content hashes, Merkle trees, hash chains and directory manifests.

The hashing comes from the fully managed, SIMD-accelerated Blake3 package (BSD-2-Clause). Targets net8.0.

Install

dotnet add package Masterly.Hash.Integrity.Blake3

Quickstart

using Masterly.Hash.Integrity;
using Masterly.Hash.Integrity.Blake3;

Blake3Algorithms.Register();   // once at startup, so "blake3:..." strings parse

ContentHash hash = await ContentHasher.ComputeFileAsync("big.iso", Blake3Algorithms.Blake3);
bool ok = await ContentHasher.VerifyFileAsync("big.iso", ContentHash.Parse(hash.ToString()));

var mac = Blake3Algorithms.Keyed("k1", key32Bytes);
DirectoryManifest manifest = await DirectoryManifest.CreateAsync("/srv/app", mac);

Security notes

  • Plain BLAKE3 detects changes but anyone can recompute it. If an attacker may also rewrite the stored hashes, use Keyed with a key kept outside the data store.
  • Keys must be exactly 32 bytes and should be random (for example HashPrimitives.RandomBytes(32)). The key is copied when the algorithm is created. The hasher state is cleared when each digest is disposed.
  • Merkle trees built with BLAKE3 use the RFC 9162 structure, but they are not interoperable with Certificate Transparency, which requires SHA-256.
