Soenneker.Managers.HashChecking

Compares BLAKE3 hashes for a file or directory against a hash stored in a repository checkout.

Install

dotnet add package Soenneker.Managers.HashChecking

Usage

using Microsoft.Extensions.DependencyInjection;
using Soenneker.Managers.HashChecking.Abstract;
using Soenneker.Managers.HashChecking.Registrars;

services.AddHashCheckingManagerAsSingleton();

IHashCheckingManager hashes =
    serviceProvider.GetRequiredService<IHashCheckingManager>();

(bool needsUpdate, string newHash) = await hashes.CheckForHashDifferences(
    gitDirectory: repositoryPath,
    filePath: downloadedBinaryPath,
    hashFileName: "hash.txt",
    cancellationToken);

if (needsUpdate)
{
    // Validate and publish the new artifact, then persist newHash.
}

The methods only compare hashes. They do not write the hash file or update Git.

What you get

IHashCheckingManager — Handles hashing and verification of binaries.
HashCheckingManagerRegistrar — Handles hashing and verification of binaries.

API at a glance

API	What it does	Result / important behavior
`IHashCheckingManager.CheckForHashDifferences(gitDirectory, filePath, hashFileName, cancellationToken)`	Checks whether the specified file's hash differs from the stored hash in the given Git directory and determines if an update is required.	A value task that returns a tuple containing a boolean indicating whether an update is needed, and the new hash value if a difference is detected.
`IHashCheckingManager.CheckForHashDifferencesOfDirectory(gitDirectory, inputDirectory, hashFileName, cancellationToken)`	Compares the hash of the specified input directory with the hash stored in the given Git directory to determine if an update is required.	A tuple containing a Boolean value indicating whether the input directory needs to be updated (`true` if an update is required; otherwise, `false`), and a string representing the newly computed hash of the input directory.
`HashCheckingManagerRegistrar.AddHashCheckingManagerAsSingleton(services)`	Adds `IHashCheckingManager` as a singleton service.	The same service collection, so additional registrations can be chained.
`HashCheckingManagerRegistrar.AddHashCheckingManagerAsScoped(services)`	Adds `IHashCheckingManager` as a scoped service.	The same service collection, so additional registrations can be chained.

Important behavior

A missing or unreadable stored hash returns needsUpdate: true with the newly calculated hash.
Stored leading/trailing whitespace is ignored during comparison.
hashFileName may be a relative path inside gitDirectory; paths that escape the checkout are rejected.
Directory comparisons use IBlake3Util.HashDirectoryToAggregateString. Use the returned aggregate string as the next stored value.

Practical notes

Hashing large files or directories can be expensive; pass cancellation through from the owning runner.
