feat(crypto): Complete Phase 2 - Configuration-driven crypto architecture with 100% compliance
## Summary
This commit completes Phase 2 of the configuration-driven crypto architecture, achieving
100% crypto compliance by eliminating all hardcoded cryptographic implementations.
## Key Changes
### Phase 1: Plugin Loader Infrastructure
- **Plugin Discovery System**: Created StellaOps.Cryptography.PluginLoader with manifest-based loading
- **Configuration Model**: Added CryptoPluginConfiguration with regional profiles support
- **Dependency Injection**: Extended DI to support plugin-based crypto provider registration
- **Regional Configs**: Created appsettings.crypto.{international,russia,eu,china}.yaml
- **CI Workflow**: Added .gitea/workflows/crypto-compliance.yml for audit enforcement
### Phase 2: Code Refactoring
- **API Extension**: Added ICryptoProvider.CreateEphemeralVerifier for verification-only scenarios
- **Plugin Implementation**: Created OfflineVerificationCryptoProvider with ephemeral verifier support
- Supports ES256/384/512, RS256/384/512, PS256/384/512
- SubjectPublicKeyInfo (SPKI) public key format
- **100% Compliance**: Refactored DsseVerifier to remove all BouncyCastle cryptographic usage
- **Unit Tests**: Created OfflineVerificationProviderTests with 39 passing tests
- **Documentation**: Created comprehensive security guide at docs/security/offline-verification-crypto-provider.md
- **Audit Infrastructure**: Created scripts/audit-crypto-usage.ps1 for static analysis
### Testing Infrastructure (TestKit)
- **Determinism Gate**: Created DeterminismGate for reproducibility validation
- **Test Fixtures**: Added PostgresFixture and ValkeyFixture using Testcontainers
- **Traits System**: Implemented test lane attributes for parallel CI execution
- **JSON Assertions**: Added CanonicalJsonAssert for deterministic JSON comparisons
- **Test Lanes**: Created test-lanes.yml workflow for parallel test execution
### Documentation
- **Architecture**: Created CRYPTO_CONFIGURATION_DRIVEN_ARCHITECTURE.md master plan
- **Sprint Tracking**: Created SPRINT_1000_0007_0002_crypto_refactoring.md (COMPLETE)
- **API Documentation**: Updated docs2/cli/crypto-plugins.md and crypto.md
- **Testing Strategy**: Created testing strategy documents in docs/implplan/SPRINT_5100_0007_*
## Compliance & Testing
- ✅ Zero direct System.Security.Cryptography usage in production code
- ✅ All crypto operations go through ICryptoProvider abstraction
- ✅ 39/39 unit tests passing for OfflineVerificationCryptoProvider
- ✅ Build successful (AirGap, Crypto plugin, DI infrastructure)
- ✅ Audit script validates crypto boundaries
## Files Modified
**Core Crypto Infrastructure:**
- src/__Libraries/StellaOps.Cryptography/CryptoProvider.cs (API extension)
- src/__Libraries/StellaOps.Cryptography/CryptoSigningKey.cs (verification-only constructor)
- src/__Libraries/StellaOps.Cryptography/EcdsaSigner.cs (fixed ephemeral verifier)
**Plugin Implementation:**
- src/__Libraries/StellaOps.Cryptography.Plugin.OfflineVerification/ (new)
- src/__Libraries/StellaOps.Cryptography.PluginLoader/ (new)
**Production Code Refactoring:**
- src/AirGap/StellaOps.AirGap.Importer/Validation/DsseVerifier.cs (100% compliant)
**Tests:**
- src/__Libraries/__Tests/StellaOps.Cryptography.Plugin.OfflineVerification.Tests/ (new, 39 tests)
- src/__Libraries/__Tests/StellaOps.Cryptography.PluginLoader.Tests/ (new)
**Configuration:**
- etc/crypto-plugins-manifest.json (plugin registry)
- etc/appsettings.crypto.*.yaml (regional profiles)
**Documentation:**
- docs/security/offline-verification-crypto-provider.md (600+ lines)
- docs/implplan/CRYPTO_CONFIGURATION_DRIVEN_ARCHITECTURE.md (master plan)
- docs/implplan/SPRINT_1000_0007_0002_crypto_refactoring.md (Phase 2 complete)
## Next Steps
Phase 3: Docker & CI/CD Integration
- Create multi-stage Dockerfiles with all plugins
- Build regional Docker Compose files
- Implement runtime configuration selection
- Add deployment validation scripts

# StellaOps.Cryptography.Plugin.OfflineVerification
|
||||
|
||||
Cryptographic provider for offline/air-gapped environments using .NET BCL cryptography.
|
||||
|
||||
## Overview
|
||||
|
||||
The `OfflineVerificationCryptoProvider` wraps `System.Security.Cryptography` in the `ICryptoProvider` abstraction, enabling configuration-driven crypto while maintaining offline verification capabilities without external dependencies.
|
||||
|
||||
## Supported Algorithms
|
||||
|
||||
### Signing & Verification
|
||||
- **ECDSA**: ES256 (P-256/SHA-256), ES384 (P-384/SHA-384), ES512 (P-521/SHA-512)
|
||||
- **RSA PKCS1**: RS256, RS384, RS512
|
||||
- **RSA-PSS**: PS256, PS384, PS512
|
||||
|
||||
### Content Hashing
|
||||
- **SHA-2**: SHA-256, SHA-384, SHA-512 (supports both `SHA-256` and `SHA256` formats)
|
||||
|
||||
## When to Use
|
||||
|
||||
Use `OfflineVerificationCryptoProvider` when:
|
||||
|
||||
1. **Offline/Air-Gapped Environments**: Systems without network access or external cryptographic services
|
||||
2. **Default Cryptography**: Standard NIST-approved algorithms without regional compliance requirements
|
||||
3. **Container Scanning**: AirGap module, Scanner module, and other components that need deterministic signing
|
||||
4. **Testing**: Local development and testing without hardware security modules
|
||||
|
||||
**Do NOT use when:**
|
||||
- Regional compliance required (eIDAS, GOST R 34.10, SM2) - use specialized plugins instead
|
||||
- FIPS 140-2 Level 3+ hardware security required - use HSM plugins
|
||||
- Key management by external providers - use cloud KMS plugins (AWS KMS, Azure Key Vault, etc.)
|
||||
|
||||
## Usage
|
||||
|
||||
### Basic Hashing
|
||||
|
||||
```csharp
|
||||
using StellaOps.Cryptography;
|
||||
using StellaOps.Cryptography.Plugin.OfflineVerification;
|
||||
|
||||
var provider = new OfflineVerificationCryptoProvider();
|
||||
var hasher = provider.GetHasher("SHA-256");
|
||||
var hash = hasher.ComputeHash(data);
|
||||
```
|
||||
|
||||
### Signing with Stored Keys
|
||||
|
||||
```csharp
|
||||
var provider = new OfflineVerificationCryptoProvider();
|
||||
|
||||
// Add key to provider
|
||||
var signingKey = new CryptoSigningKey(
|
||||
reference: new CryptoKeyReference("my-key"),
|
||||
algorithmId: "ES256",
|
||||
privateParameters: ecParameters,
|
||||
createdAt: DateTimeOffset.UtcNow);
|
||||
|
||||
provider.UpsertSigningKey(signingKey);
|
||||
|
||||
// Get signer and sign data
|
||||
var signer = provider.GetSigner("ES256", new CryptoKeyReference("my-key"));
|
||||
var signature = await signer.SignAsync(data);
|
||||
```
|
||||
|
||||
### Ephemeral Verification (New in 1.0)
|
||||
|
||||
For scenarios where you only have a public key (e.g., DSSE verification, JWT verification):
|
||||
|
||||
```csharp
|
||||
var provider = new OfflineVerificationCryptoProvider();
|
||||
|
||||
// Public key in SubjectPublicKeyInfo (DER-encoded) format
|
||||
byte[] publicKeyBytes = ...; // From certificate, JWKS, or inline
|
||||
|
||||
// Create ephemeral verifier
|
||||
var verifier = provider.CreateEphemeralVerifier("PS256", publicKeyBytes);
|
||||
|
||||
// Verify signature
|
||||
var isValid = await verifier.VerifyAsync(message, signature);
|
||||
```
|
||||
|
||||
**Supported Algorithms for Ephemeral Verification:**
|
||||
- ECDSA: ES256, ES384, ES512
|
||||
- RSA PKCS1: RS256, RS384, RS512
|
||||
- RSA-PSS: PS256, PS384, PS512
|
||||
|
||||
**Key Format:**
|
||||
- Public keys must be in **SubjectPublicKeyInfo** (SPKI) format (DER-encoded)
|
||||
- This is the standard format used in X.509 certificates, JWKs, and TLS
|
||||
|
||||
### Dependency Injection
|
||||
|
||||
```csharp
|
||||
services.AddStellaOpsCryptoFromConfiguration(configuration);
|
||||
```
|
||||
|
||||

||||
|
||||
### ICryptoProvider.CreateEphemeralVerifier
|
||||
|
||||
```csharp
|
||||
ICryptoSigner CreateEphemeralVerifier(string algorithmId, ReadOnlySpan<byte> publicKeyBytes)
|
||||
```
|
||||
|
||||
Creates a verification-only signer from raw public key bytes. Useful for:
|
||||

|
||||
- JWT/JWS verification without key persistence
|
||||
- Ad-hoc signature verification in offline scenarios
|
||||

||||
**Parameters:**
|
||||
- `algorithmId`: Algorithm identifier (ES256, RS256, PS256, etc.)
|
||||
- `publicKeyBytes`: Public key in SubjectPublicKeyInfo format (DER-encoded)
|
||||
|
||||
**Returns:**
|
||||
- `ICryptoSigner` instance with `VerifyAsync` support only
|
||||
- `SignAsync` throws `NotSupportedException`
|
||||
- `KeyId` returns `"ephemeral"`
|
||||
- `AlgorithmId` returns the specified algorithm
|
||||
|
||||
**Throws:**
|
||||
- `NotSupportedException`: If algorithm not supported or public key format invalid
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### Internal Architecture

|
||||
```
|
||||
|
||||
### Plugin Boundaries
|
||||
|
||||
**Allowed** within this plugin:
|
||||
- Direct usage of `System.Security.Cryptography` (internal implementation)
|
||||
- Creation of `ECDsa`, `RSA`, `SHA256`, `SHA384`, `SHA512` instances
|
||||
- Key import/export operations
|
||||
|
||||
**Not allowed** outside this plugin:
|
||||
- Direct crypto library usage in production code
|
||||
- All consumers must use `ICryptoProvider` abstraction
|
||||
|
||||
This boundary is enforced by:
|
||||
- `scripts/audit-crypto-usage.ps1` - Static analysis
|
||||
- `.gitea/workflows/crypto-compliance.yml` - CI validation
|
||||
|
||||
## Testing
|
||||
|
||||
Run unit tests:
|
||||
|
||||
```bash
|
||||
dotnet test src/__Libraries/__Tests/StellaOps.Cryptography.Plugin.OfflineVerification.Tests
|
||||
```
|
||||
|
||||
**Test Coverage:**
|
||||
- 39 unit tests covering all algorithms and scenarios
|
||||
- Provider capability matrix validation
|
||||
- Known-answer tests for SHA-256/384/512
|
||||
- ECDSA and RSA signing/verification roundtrips
|
||||
- Ephemeral verifier creation and usage
|
||||
- Error handling (unsupported algorithms, tampered data)
|
||||
|
||||
## Performance
|
||||
|
||||
The abstraction layer is designed to be zero-cost:
|
||||
- No heap allocations in hot paths
|
||||
- Direct delegation to .NET BCL primitives
|
||||
- `ReadOnlySpan<byte>` for memory efficiency
|
||||
|
||||
Benchmark results should match direct `System.Security.Cryptography` usage within measurement error.
|
||||
|
||||
## Security Considerations
|
||||
|
||||
1. **Key Storage**: This provider stores keys in-memory only. For persistent key storage, integrate with a key management system.
|
||||
|
||||
2. **Ephemeral Verification**: Public keys for ephemeral verification are not cached or validated against a trust store. Callers must perform their own trust validation.
|
||||
|
||||
3. **Algorithm Hardening**:
|
||||
- RSA key sizes: 2048-bit minimum recommended
|
||||
- ECDSA curves: Only NIST P-256/384/521 supported
|
||||
- Hash algorithms: SHA-2 family only (SHA-1 explicitly NOT supported)
|
||||
|
||||
4. **Offline Trust**: In offline scenarios, establish trust through:
|
||||
- Pre-distributed public key fingerprints
|
||||
- Certificate chains embedded in airgap bundles
|
||||
- Out-of-band key verification
|
||||
|
||||
## Compliance
|
||||
|
||||
- **NIST FIPS 186-4**: ECDSA with approved curves (P-256, P-384, P-521)
|
||||
- **NIST FIPS 180-4**: SHA-256, SHA-384, SHA-512
|
||||
- **RFC 8017**: RSA PKCS#1 v2.2 (RSASSA-PKCS1-v1_5 and RSASSA-PSS)
|
||||
- **RFC 6979**: Deterministic ECDSA (when used with BouncyCastle fallback)
|
||||
|
||||
**Not compliant with:**

||||
|
||||
Test infrastructure and fixtures for StellaOps projects. Provides deterministic time/random, canonical JSON assertions, snapshot testing, database fixtures, and OpenTelemetry capture.
|
||||
|
||||
## Features
|
||||
|
||||
### Deterministic Time
|
||||
```csharp
|
||||
using StellaOps.TestKit.Time;
|
||||
|
||||
// Create a clock at a fixed time
|
||||
var clock = new DeterministicClock();
|
||||
var now = clock.UtcNow; // 2025-01-01T00:00:00Z
|
||||
|
||||
// Advance time
|
||||
clock.Advance(TimeSpan.FromMinutes(5));
|
||||
|
||||
// Or use helpers
|
||||
var clock2 = DeterministicClockExtensions.AtTestEpoch();
|
||||
var clock3 = DeterministicClockExtensions.At("2025-06-15T10:30:00Z");
|
||||
```
|
||||
|
||||
### Deterministic Random
|
||||
```csharp
|
||||
using StellaOps.TestKit.Random;
|
||||
|
||||
// Create deterministic RNG with standard test seed (42)
|
||||
var rng = DeterministicRandomExtensions.WithTestSeed();
|
||||
|
||||
// Generate reproducible values
|
||||
var number = rng.Next(1, 100);
|
||||
var text = rng.NextString(10);
|
||||
var item = rng.PickOne(new[] { "a", "b", "c" });
|
||||
```
|
||||
|
||||
### Canonical JSON Assertions
|
||||
```csharp
|
||||
using StellaOps.TestKit.Json;
|
||||
|
||||
// Assert JSON equality (ignores formatting)
|
||||
CanonicalJsonAssert.Equal(expectedJson, actualJson);
|
||||
|
||||
// Assert object equivalence
|
||||
CanonicalJsonAssert.EquivalentObjects(expectedObj, actualObj);
|
||||
|
||||
// Hash-based regression testing
|
||||
var hash = CanonicalJsonAssert.ComputeHash(json);
|
||||
CanonicalJsonAssert.MatchesHash("abc123...", json);
|
||||
```
|
||||
|
||||
### Snapshot Testing
|
||||
```csharp
|
||||
using StellaOps.TestKit.Snapshots;
|
||||
|
||||
public class MyTests
|
||||
{
|
||||
[Fact]
|
||||
public void TestOutput()
|
||||
{
|
||||
var output = GenerateSomeOutput();
|
||||
|
||||
// Compare against __snapshots__/test_output.txt
|
||||
var snapshotPath = SnapshotHelper.GetSnapshotPath("test_output");
|
||||
SnapshotHelper.VerifySnapshot(output, snapshotPath);
|
||||
}
|
||||
|
||||
[Fact]
|
||||
public void TestJsonOutput()
|
||||
{
|
||||
var obj = new { Name = "test", Value = 42 };
|
||||
|
||||
// Compare JSON serialization
|
||||
var snapshotPath = SnapshotHelper.GetSnapshotPath("test_json", ".json");
|
||||
SnapshotHelper.VerifyJsonSnapshot(obj, snapshotPath);
|
||||
}
|
||||
}
|
||||
|
||||
// Update snapshots: set environment variable UPDATE_SNAPSHOTS=1
|
||||
```
|
||||
|
||||
### PostgreSQL Fixture
|
||||
```csharp
|
||||
using StellaOps.TestKit.Fixtures;
|
||||
using Xunit;
|
||||
|
||||
[Collection("Postgres")]
|
||||
public class DatabaseTests
|
||||
{
|
||||
private readonly PostgresFixture _postgres;
|
||||
|
||||
public DatabaseTests(PostgresFixture postgres)
|
||||
{
|
||||
_postgres = postgres;
|
||||
}
|
||||
|
||||
[Fact]
|
||||
public async Task TestQuery()
|
||||
{
|
||||
// Use connection string
|
||||
await using var conn = new Npgsql.NpgsqlConnection(_postgres.ConnectionString);
|
||||
await conn.OpenAsync();
|
||||
|
||||
// Execute SQL
|
||||
await _postgres.ExecuteSqlAsync("CREATE TABLE test (id INT)");
|
||||
|
||||
// Create additional databases
|
||||
await _postgres.CreateDatabaseAsync("otherdb");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Valkey/Redis Fixture
|
||||
```csharp
|
||||
using StellaOps.TestKit.Fixtures;
|
||||
using Xunit;
|
||||
|
||||
[Collection("Valkey")]
|
||||
public class CacheTests
|
||||
{
|
||||
private readonly ValkeyFixture _valkey;
|
||||
|
||||
public CacheTests(ValkeyFixture valkey)
|
||||
{
|
||||
_valkey = valkey;
|
||||
}
|
||||
|
||||
[Fact]
|
||||
public void TestCache()
|
||||
{
|
||||
var connectionString = _valkey.ConnectionString;
|
||||
// Use with your Redis/Valkey client
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### OpenTelemetry Capture
|
||||
```csharp
|
||||
using StellaOps.TestKit.Telemetry;
|
||||
|
||||
[Fact]
|
||||
public void TestTracing()
|
||||
{
|
||||
using var otel = new OTelCapture("my-service");
|
||||
|
||||
// Code that emits traces
|
||||
using (var activity = otel.ActivitySource.StartActivity("operation"))
|
||||
{
|
||||
activity?.SetTag("key", "value");
|
||||
}
|
||||
|
||||
// Assert traces
|
||||
otel.AssertActivityExists("operation");
|
||||
otel.AssertActivityHasTag("operation", "key", "value");
|
||||
|
||||
// Get summary for debugging
|
||||
Console.WriteLine(otel.GetTraceSummary());
|
||||
}
|
||||
```
|
||||
|
||||
## Usage in Tests
|
||||
|
||||
Add to your test project:
|
||||
```xml
|
||||
<ItemGroup>
|
||||
<ProjectReference Include="..\..\__Libraries\StellaOps.TestKit\StellaOps.TestKit.csproj" />
|
||||
</ItemGroup>
|
||||
```
|
||||
|
||||
## Design Principles
|
||||
|
||||
- **Determinism**: All utilities produce reproducible results
|
||||
- **Offline-first**: No network dependencies (uses Testcontainers for local infrastructure)
|
||||
- **Minimal dependencies**: Only essential packages
|
||||
- **xUnit-friendly**: Works seamlessly with xUnit fixtures and collections
