PostQuantum.Hybrid.AspNetCore

ASP.NET Core dependency-injection extensions for PostQuantum.Hybrid.

Lets you load hybrid KEM and signature keys from configuration and inject them into your controllers and services without writing boilerplate.

Install

dotnet add package PostQuantum.Hybrid.AspNetCore

Quick start

using PostQuantum.Hybrid.AspNetCore;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddPostQuantumHybrid(builder.Configuration.GetSection("Crypto"));

var app = builder.Build();

app.MapGet("/sign", (IHybridSignatureKeyProvider keys, string message) =>
{
    var bytes = System.Text.Encoding.UTF8.GetBytes(message);
    var sig = PostQuantum.Hybrid.HybridSignature.Sign(keys.PrivateKey, bytes);
    return Convert.ToBase64String(sig);
});

app.Run();

appsettings.json

{
  "Crypto": {
    // KEM key pair — both halves required.
    "KemPublicKeyPath":  "/run/secrets/hybrid-kem.pub.pem",
    "KemPrivateKeyPath": "/run/secrets/hybrid-kem.priv.pem",

    // Signature key pair — both halves required.
    "SignaturePublicKeyPath":  "/run/secrets/hybrid-sig.pub.pem",
    "SignaturePrivateKeyPath": "/run/secrets/hybrid-sig.priv.pem"
  }
}

Each key half accepts either inline PEM (*KeyPem) or a file path (*KeyPath); if both are supplied, the inline PEM wins.

You can omit a family entirely if your app doesn't need it (e.g. only-sign apps don't need KEM keys); the corresponding provider will throw on first use rather than at startup.

What you get

Service Purpose
IHybridKemKeyProvider Long-lived recipient KEM key for decapsulation.
IHybridSignatureKeyProvider Long-lived signing key + public key.
HybridCryptoOptions Strongly-typed configuration.

Both providers are registered as singletons. The underlying private keys are disposed when the host shuts down.

Security guidance

  • Never commit KemPrivateKeyPem / SignaturePrivateKeyPem to source control. Use KemPrivateKeyPath / SignaturePrivateKeyPath pointing at a secret-managed file, or load from a real secret store (Azure Key Vault, AWS Secrets Manager, HashiCorp Vault).
  • Use file permissions on the key file (chmod 600 on Linux; a restricted NTFS ACL on Windows).
  • Rotate keys. Loading the key is one-shot; rotation requires restarting the host. For zero-downtime rotation, implement a custom IHybridKeyProvider that watches its source.
