PostQuantum.FileEncryption.Extensions.DependencyInjection

Microsoft.Extensions.DependencyInjection integration for PostQuantum.FileEncryption and PostQuantum.FileEncryption.Hybrid. One call registers the encryptor and decryptor services in any host that uses the standard .NET service container — ASP.NET Core, Worker Services, console hosts with Microsoft.Extensions.Hosting.

dotnet add package PostQuantum.FileEncryption.Extensions.DependencyInjection

Usage

Passphrase encryption only (registers PqFileEncryptor + PqFileDecryptor):

builder.Services.AddPqFileEncryption();

Passphrase and X25519 + ML-KEM-768 hybrid recipient encryption (additionally registers PqHybridEncryptor + PqHybridDecryptor):

builder.Services.AddPqHybridFileEncryption();

Detached Ed25519 + ML-DSA-65 signing and verification (registers PqSigner + PqVerifier; key material stays in your own key storage and is passed per call):

builder.Services.AddPqSigning();

Then inject and use:

public sealed class ArchiveService(PqFileEncryptor encryptor, PqFileDecryptor decryptor)
{
    public Task ProtectAsync(string path, string passphrase, CancellationToken ct) =>
        encryptor.EncryptFileAsync(path, path + ".pqfe", passphrase, cancellationToken: ct);
}

Options

Pass a PqEncryptionOptions to tune encryption (KDF choice, work factors, chunk size). Omitting it gives you the library's secure defaults:

builder.Services.AddPqFileEncryption(PqEncryptionOptions.Argon2id);

Options never affect decryption — the decryptor reads every parameter from the authenticated container header, so a service registered with one set of options decrypts files produced with any other.

Behavior

Singletons. The encryptor/decryptor types are thread-safe and hold no per-operation state; one instance serves the whole host.
TryAdd semantics. If your application already registered its own instance of any of these types, your registration wins.
Lockstep versioning. This package always pins PostQuantum.FileEncryption, PostQuantum.FileEncryption.Hybrid, and PostQuantum.FileEncryption.Signing at its own version.

1.4.1 — tracks PostQuantum.FileEncryption 1.4.1 in lockstep. Documentation and packaging patch only: corrects the package README install snippets and version references that still cited 1.3.0. No API changes. No change to the .pqfe v2 container format, which remains FROZEN for the 1.x line. See CHANGELOG.md.
