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}.

Loading failed

A release for hosts on the Orleans execution model. A durable timer now answers its tick while its handler runs, so a
long handler leaves no reminder error in the silo's log, and a timer that fails is logged by the framework with its
owner and purpose. A commit no longer constructs every registered projection to learn which store readers to wake. No
API change, no schema change and no migration.

### Changed

- **A commit no longer constructs every projection.** On the Orleans execution model, every command that committed
 facts constructed each registered projection, with its dependencies, only to learn the names of the store readers to
 wake. The names are now worked out once per silo, and the wait for a projection, the rebuild and the full replay's
 checkpoint reset use the same list. A rebuild of a name that is not registered is refused before any reader is
 paused, with the same message as before.

### Fixed

- **A durable timer answers its tick while its handler runs.** On the Orleans execution model, a durable timer's
 reminder call stayed open until its handler returned, so a handler longer than the runtime's response timeout made
 Orleans log `Could not deliver reminder tick` at Error for every tick it outlasted. The tick is now answered at once
 and the handler runs in a call that carries no response timeout. The timer still fires once per due time, a tick
 during its handler still does nothing, and a handler stopped with its silo still fires again on the next one.
- **A failing timer is logged.** A durable timer whose handler threw — or whose owner check or unregistration
 failed — was visible only as Orleans' reminder error line. It is now logged as `117_137` `TimerFiringFailed` (Error)
 with the owner, the purpose and the exception, and the timer fires again after its retry period as before.
