It wraps .NET BCL cryptography (`System.Security.Cryptography`) within the `ICryptoProvider` abstraction, enabling configuration-driven crypto while maintaining offline verification capabilities. +The **OfflineVerificationCryptoProvider** is a cryptographic abstraction layer that wraps .NET BCL (`System.Security.Cryptography`) to enable **configuration-driven cryptography** in offline, air-gapped, and sovereignty-constrained environments. -This provider is particularly useful for: -- **Air-gapped deployments** where hardware security modules (HSMs) are unavailable -- **Offline bundle verification** in disconnected environments -- **Development and testing** environments -- **Fallback scenarios** when regional crypto providers are unavailable +### Purpose -## When to Use This Provider +- **Offline Operations**: Function without network access to external cryptographic services +- **Deterministic Behavior**: Reproducible signatures and hashes for compliance auditing +- **Zero External Dependencies**: No cloud KMS, HSMs, or online certificate authorities required +- **Regional Neutrality**: NIST-approved algorithms without regional compliance constraints -### ✅ Recommended Use Cases +### Key Features -1. **Air-Gapped Bundle Verification** - - Verifying DSSE-signed evidence bundles in disconnected environments - - Validating attestations without external connectivity - - Offline policy verification +- ECDSA (ES256/384/512) and RSA (RS256/384/512, PS256/384/512) signing/verification +- SHA-2 family hashing (SHA-256/384/512) +- Ephemeral verification for public-key-only scenarios (DSSE, JWT, JWS) +- Configuration-driven plugin architecture with priority-based selection +- Zero-cost abstraction over .NET BCL primitives -2. **Development & Testing** - - Local development without HSM dependencies - - CI/CD pipelines for automated testing - - Integration test environments +--- -3. **Fallback Provider** - - When regional providers (GOST, SM, eIDAS) are unavailable - - Default offline verification path +## Architecture -### ❌ NOT Recommended For +### Component Hierarchy -1. **Production Signing Operations** - Use HSM-backed providers instead -2. **Compliance-Critical Scenarios** - Use certified providers (FIPS, eIDAS, etc.) -3. **High-Value Key Storage** - Use hardware-backed key storage +```

Always Use TestCategories + +Tag every test with the appropriate category: + +```csharp +[Fact, Trait("Category", TestCategories.Unit)] +public void MyUnitTest() { } +``` + +This enables CI lane filtering and improves test discoverability. + +### 2. Prefer Deterministic Primitives + +Avoid `DateTime.UtcNow`, `Guid.NewGuid()`, `Random` in tests. Use TestKit alternatives: + +```csharp +// ❌ Flaky test (time-dependent) +var expiration = DateTime.UtcNow.AddHours(1); + +// ✅ Deterministic test +using var time = new DeterministicTime(DateTime.UtcNow); +var expiration = time.UtcNow.AddHours(1); +``` + +### 3. Use Snapshot Tests for Complex Outputs + +For large JSON outputs (SBOM, VEX, attestations), snapshot testing is more maintainable than manual assertions: + +```csharp +// ❌ Brittle manual assertions +Assert.Equal("SPDX-3.0.1", sbom.SpdxVersion); +Assert.Equal(42, sbom.Packages.Count); +// ...hundreds of assertions... + +// ✅ Snapshot testing +SnapshotAssert.MatchesSnapshot(sbom, "MySbomSnapshot"); +``` + +### 4. Isolate Integration Tests + +Use TestCategories to separate fast unit tests from slow integration tests: + +```csharp +[Fact, Trait("Category", TestCategories.Unit)] +public void FastTest() { /* no external dependencies */ } + +[Fact, Trait("Category", TestCategories.Integration)] +public async Task SlowTest() { /* uses PostgresFixture */ } +``` + +In CI, run Unit tests first for fast feedback, then Integration tests in parallel. + +### 5. Document Snapshot Baselines + +When updating snapshots (`UPDATE_SNAPSHOTS=1`), add a commit message explaining why: + +```bash +git commit -m "Update SBOM snapshot: added new package metadata fields" +``` + +This helps reviewers understand intentional vs. accidental changes. + +--- + +## Troubleshooting + +### Snapshot Mismatch + +**Error:** `Snapshot 'MySbomSnapshot' does not match expected.` + +**Solution:** +1.
