License: FSL-1.1-MIT (Functional Source License — source-available; converts to MIT after 2 years). Not OSI-approved OSS.

Dependency-light key store and envelope encryption for Stratara. Provides a production IKeyStore with KEK-wrapped, versioned per-scope data-encryption keys (rotation, revoke, and crypto-shred), a file-backed master-key provider, and an AES-GCM blob encryptor — referencing only Stratara.Abstractions + BCL crypto. No EF Core, RabbitMQ, Redis, or cloud SDKs in the graph.

Quick start

// appsettings / secrets:
// "Stratara": { "KeyStore": { "MasterKeyBase64": "<openssl rand -base64 32>", "StorePath": "/var/run/secrets/keystore.json" } }

builder.Services.AddStrataraFileKeyStore(builder.Configuration);

// Encrypt a blob bound to a tenant scope + purpose:
var scope = new KeyScope(DataSensitivityLevel.TenantScoped, tenantId: "acme-corp");
await using var encrypted = await encryptor.EncryptAsync(plainStream, scope, purpose: "attachment");
await using var plain = await encryptor.DecryptAsync(encrypted, scope);

What's inside

  • EnvelopeFileKeyStore (IKeyStore) — random 32-byte DEK per scope/version, KEK-wrapped with AES-256-GCM (wrap AAD bound to the key id, so a wrapped DEK can't be moved to another scope). The store file holds only wrapped DEKs + metadata, never plaintext. RotateAsync adds a version; RevokeAsync makes one version undecryptable; EraseScopeAsync deletes all versions for a scope (GDPR Art. 17 crypto-shred). DEKs are zeroed after use; the store file is written 0600 on Unix.
  • FileMasterKeyProvider (IMasterKeyProvider) — KEK from MasterKeyBase64, validated to decode to exactly 32 bytes (AES-256) at startup. The custody seam: swap for an HSM / KMS / vault provider later without touching the stored data.
  • AesGcmSecureBlobEncryptor (ISecureBlobEncryptor) — AES-GCM stream encryption with a purpose-bound AAD ({tenant}||{purpose}) and a versioned, self-describing format (v2 leading byte). Reads legacy streams without the version byte; set Stratara:BlobEncryption:LegacyBlobsCarryPurpose to match the legacy layout.
  • DummyKeyStore — Development-only deterministic fallback (throws outside Development).

Key id schema

{level}:{tenant}:{user}:v{N} — e.g. TenantScoped:acme-corp::v1. GetOrCreateCurrentKeyAsync returns the highest non-revoked version (creating v1 if none); RotateAsync creates v{N+1}.

Stratara.Infrastructure

Infrastructure glue for the Stratara framework — authorization decorators, configuration providers, and DI composition helpers that wire Mediator, Outbox, Identity, and EF Core into a hosted app.
Stratara.Testing

Test doubles and assertion helpers for applications built on the Stratara framework — an in-memory IKeyStore, an in-memory IMessageBus, a preset ISessionContextProvider, deterministic tenant ids, and a given/when/then aggregate rehydration harness. Drop the Postgres/RabbitMQ testcontainers for unit tests.

### Added

- **New package `Stratara.Testing`** — test doubles and assertion helpers so consumers can
 unit-test Stratara-based code without Postgres or RabbitMQ testcontainers. Reference it from
 test projects only.
 - `AggregateTestHarness<T>` + `Aggregate.Rehydrate<T>(...)` — given/when/then rehydration of an
   aggregate from events using the same reflection-based `Apply(...)` dispatch as the production
   aggregation service. It throws on an event with no matching `Apply` overload so a forgotten or
   mistyped overload fails the test; opt back into the production-lenient skip with
   `IgnoringUnmappedEvents()`.
 - `InMemoryKeyStore` — an `IKeyStore` that mints random 256-bit DEKs per `KeyScope` and supports
   rotation / revocation / scope-erasure without a master KEK or key file.
 - `TestBlobEncryptor.CreateAesGcm()` — the real AES-GCM `ISecureBlobEncryptor` over an
   `InMemoryKeyStore`, so blob round-trips exercise production encryption.
 - `InMemoryMessageBus` — an `IMessageBus` with synchronous in-process dispatch and a `Published`
   list for assertions.
 - `TestSessionContext` / `TestSessionContextProvider` — preset Actor/Subject `SessionContext`
   values and an `ISessionContextProvider` double.
 - `TestTenants.Of("acme")` — stable, deterministic tenant/user ids from readable slugs.
   `TestSessionContext` sets both correlation and causation ids so the context can drive
   event-store writes.
 - `TestEvent.Create(payload, ...)` — wrap an event payload in `IEvent<T>` with realistic
   metadata; `ProjectionTester.HandleAsync(projection, event)` — invoke a projection's private
   `HandleAsync` handler directly to unit-test it against mocked repositories.
- **New package `Stratara.Testing.EntityFrameworkCore`** — spins up the **real** event-sourcing
 write stack (`IEventSource`, `IAggregationService`, snapshots, the EF Core write store) against a
 shared in-memory SQLite database in one call, so tests exercise production code paths without
 Postgres or Docker. Reference it from test projects only.
 - `EventStoreTestHost.Create(...)` — owns the SQLite connection + service provider; exposes
   `ExecuteAsync(IEventSource)`, `AggregateAsync<T>(streamId)`, the preset `Session`, and the
   recording `Outbox`.
 - `AddStrataraTestingEventStore<TWriteDbContext>(connection, tenantId)` — the lower-level DI
   extension; `StrataraTestWriteDbContext` — a ready-made concrete write context;
   `RecordingEventBundleOutboxDispatcher` — captures emitted bundles for assertions.
 - The lockstep family grows from 22 to 24 packable packages.
