Lyo.KeyStore.Aws

AwsKeyStore (an IAmazonSecretsManager client + secret-name prefix) implements both Lyo.KeyStore.IKeyStore and Lyo.KeyStore.IKeyInventoryStore, so admin UIs and key-rotation jobs can both encrypt against it and enumerate available keyIds / versions.

The backing secret is stored as JSON ({ "<keyId>": "plaintext-or-derived-material", ... }) under a single secret per prefix. Logical version strings map onto AWS VersionId stages; unresolved version requests fall through to AWSCURRENT. String values run through key derivation so callers receive cryptographic-length KEK bytes usable by AesGcmEncryptionService and the other symmetric services in Lyo.Encryption.

AwsKeyStore API

  • IKeyStore — GetKey, GetCurrentKey, GetCurrentVersion, AddKey, UpdateKey, HasKey, metadata, salt-for-version (all sync + async variants).
  • IKeyInventoryStore — GetAvailableKeyIdsAsync(CancellationToken), GetAvailableVersionsAsync(string keyId, CancellationToken) so listings, rotation reports, and DEK migrations can pivot off the live store rather than a local index.

Options — AwsKeyStoreOptions

Property Default Notes
SectionName AwsKeyStore Default appsettings subsection.
AccessKeyId / SecretAccessKey unset Static credentials. When both are set they win over Profile. Omit to use Profile or the AWS default credential chain (IAM role, env vars, default profile).
Profile unset Named profile from ~/.aws/credentials / ~/.aws/config. Used when static keys are omitted. If set but missing, registration fails rather than falling back to default.
Region us-east-2 (when unspecified) Resolved via RegionEndpoint.GetBySystemName.
SecretNamePrefix lyo/kek fallback Logical secret prefix used to scope keys across environments (dev/MyApp/KeyStore, prod/MyApp/KeyStore, …).

Dependency injection

Extension Purpose
services.AddAwsKeyStore(Func<IServiceProvider,string> resolvePrefix) Resolve the prefix from DI (multi-tenant hosts), register AwsKeyStore as a singleton.
services.AddAwsKeyStoreFromConfiguration(IConfiguration, configSectionName = "AwsKeyStore") Bind AwsKeyStoreOptions + register IAmazonSecretsManager (when missing) + register AwsKeyStore and IKeyStore.
services.AddAmazonSecretsManagerFromConfiguration(IConfiguration, configSectionName = "AwsKeyStore") Standalone IAmazonSecretsManager registration (no keystore). Honours static keys, then Profile, then the default credential chain; also honours region.
services.AddTwoKeyEncryptionServiceKeyed(keyedServiceName, secretNamePrefix) / <TKeyStore> Register a full keyed ITwoKeyEncryptionService stack using AwsKeyStore + paired AesGcmEncryptionService for both DEK and KEK.
services.AddTwoKeyEncryptionServiceKeyed(keyedServiceName, secretNamePrefix, AwsKeyStoreOptions?) Same, but with explicit AWS options (region/credentials) rather than configuration binding.
services.AddTwoKeyEncryptionFromConfiguration(IConfiguration, keyedServiceName, configSectionName) / <TKeyStore> Bind AwsKeyStoreOptions from configuration and wire the keyed two-key stack in one call.

Note that AddAwsKeyStore(Func<...>) registers AwsKeyStore as a concrete singleton only (no IKeyStore indirection); AddAwsKeyStoreFromConfiguration and the two-key extensions also register IKeyStore so the rest of Lyo.Encryption can resolve it generically.
