From c8f3120174212e70ad217c339e8920dde04a5c76 Mon Sep 17 00:00:00 2001 From: StellaOps Bot Date: Fri, 26 Dec 2025 15:17:15 +0200 Subject: [PATCH] Add property-based tests for SBOM/VEX document ordering and Unicode normalization determinism - Implement `SbomVexOrderingDeterminismProperties` for testing component list and vulnerability metadata hash consistency. - Create `UnicodeNormalizationDeterminismProperties` to validate NFC normalization and Unicode string handling. - Add project file for `StellaOps.Testing.Determinism.Properties` with necessary dependencies. - Introduce CI/CD template validation tests including YAML syntax checks and documentation content verification. - Create validation script for CI/CD templates ensuring all required files and structures are present. --- .../workflows/cross-platform-determinism.yml | 206 +++ .gitea/workflows/deploy-keyless-verify.yml | 204 +++ .gitea/workflows/release-keyless-sign.yml | 399 ++++++

Why Determinism Matters + +StellaOps is built on **proof-of-state**: every verdict, attestation, and replay must be reproducible. Non-determinism breaks: + +- **Signature verification:** Different serialization β†’ different digest β†’ invalid signature. +- **Replay guarantees:** Feed snapshots that produce different hashes cannot be replayed. +- **Audit trails:** Compliance teams require bit-exact reproduction of historical scans. +- **Cross-platform compatibility:** Windows/Linux/macOS must produce identical outputs. + +--- + +## 2. RFC 8785 JSON Canonicalization Scheme (JCS) + +All JSON that participates in digest computation **must** use RFC 8785 JCS. This includes: + +- Attestation payloads (DSSE) +- Verdict JSON +- Policy evaluation results +- Feed snapshot manifests +- Proof bundles + +### 2.1 The Rfc8785JsonCanonicalizer + +Use the `Rfc8785JsonCanonicalizer` class for all canonical JSON operations: + +```csharp +using StellaOps.Attestor.ProofChain.Json; + +// Create canonicalizer (optionally with NFC normalization) +var canonicalizer = new Rfc8785JsonCanonicalizer(enableNfcNormalization: true); + +// Canonicalize JSON +string canonical = canonicalizer.Canonicalize(jsonString); + +// Or from JsonElement +string canonical = canonicalizer.Canonicalize(jsonElement); +``` + +### 2.2 JCS Rules Summary + +RFC 8785 requires: + +1. **No whitespace** between tokens. +2. **Lexicographic key ordering** within objects. +3. **Number serialization:** No leading zeros, no trailing zeros after decimal, integers without decimal point. +4. **String escaping:** Minimal escaping (only `"`, `\`, and control chars). +5. **UTF-8 encoding** without BOM. + +### 2.3 Common Mistakes + +❌ **Wrong:** Using `JsonSerializer.Serialize()` directly for digest input. + +```csharp +// WRONG - non-deterministic ordering +var json = JsonSerializer.Serialize(obj); +var hash = SHA256.HashData(Encoding.UTF8.GetBytes(json)); +``` + +βœ… **Correct:** Canonicalize before hashing. + +```csharp +// CORRECT - deterministic +var canonicalizer = new Rfc8785JsonCanonicalizer(); +var canonical = canonicalizer.Canonicalize(obj); +var hash = SHA256.HashData(Encoding.UTF8.GetBytes(canonical)); +``` + +--- + +## 3. Unicode NFC Normalization + +Different platforms may store the same string in different Unicode normalization forms. Enable NFC normalization when: + +- Processing user-supplied strings +- Aggregating data from multiple sources +- Working with file paths or identifiers from different systems + +```csharp +// Enable NFC for cross-platform string stability +var canonicalizer = new Rfc8785JsonCanonicalizer(enableNfcNormalization: true); +``` + +When NFC is enabled, all strings are normalized via `string.Normalize(NormalizationForm.FormC)` before serialization. + +--- + +## 4. Resolver Boundary Pattern + +**Key principle:** All data entering or leaving a "resolver" (a service that produces verdicts, attestations, or replayable state) must be canonicalized. + +### 4.1 What Is a Resolver Boundary? + +A resolver boundary is any point where: + +- Data is **serialized** for storage, transmission, or signing +- Data is **hashed** to produce a digest +- Data is **compared** for equality in replay validation + +### 4.2 Boundary Enforcement + +At resolver boundaries: + +1. **Canonicalize** all JSON payloads using `Rfc8785JsonCanonicalizer`. +2. **Sort** collections deterministically (alphabetically by key or ID). +3. **Normalize** timestamps to ISO 8601 UTC with `Z` suffix. +4. **Freeze** dictionaries using `FrozenDictionary` for stable iteration order. + +### 4.3 Example: Feed Snapshot Coordinator + +```csharp +public sealed class FeedSnapshotCoordinatorService : IFeedSnapshotCoordinator +{ + private readonly FrozenDictionary _providers; + + public FeedSnapshotCoordinatorService(IEnumerable providers, ...) + { + // Sort providers alphabetically for deterministic digest computation + _providers = providers + .OrderBy(p => p.SourceId, StringComparer.Ordinal) + .ToFrozenDictionary(p => p.SourceId, p => p, StringComparer.OrdinalIgnoreCase); + } + + private string ComputeCompositeDigest(IReadOnlyList sources) + { + // Sources are already sorted by SourceId (alphabetically) + using var sha256 = SHA256.Create(); + foreach (var source in sources.OrderBy(s => s.SourceId, StringComparer.Ordinal)) + { + // Append each source digest to the hash computation + var digestBytes = Encoding.UTF8.GetBytes(source.Digest); + sha256.TransformBlock(digestBytes, 0, digestBytes.Length, null, 0); + } + sha256.TransformFinalBlock([], 0, 0); + return $"sha256:{Convert.ToHexString(sha256.Hash!).ToLowerInvariant()}"; + } +} +``` + +--- + +## 5. Timestamp Handling + +### 5.1 Rules + +1. **Always use UTC** - never local time. +2. **ISO 8601 format** with `Z` suffix: `2025-12-27T14:30:00Z` +3. **Consistent precision** - truncate to seconds unless milliseconds are required. +4. **Use TimeProvider** for testability. + +### 5.2 Example + +```csharp +// CORRECT - UTC with Z suffix +var timestamp = timeProvider.GetUtcNow().ToString("yyyy-MM-ddTHH:mm:ssZ"); + +// WRONG - local time +var wrong = DateTime.Now.ToString("o"); + +// WRONG - inconsistent format +var wrong2 = DateTimeOffset.UtcNow.ToString(); +``` + +--- + +## 6. Numeric Stability + +### 6.1 Avoid Floating Point for Determinism + +Floating-point arithmetic can produce different results on different platforms. For deterministic values: + +- Use `decimal` for scores, percentages, and monetary values. +- Use `int` or `long` for counts and identifiers. +- If floating-point is unavoidable, document the acceptable epsilon and rounding rules. + +### 6.2 Number Serialization + +RFC 8785 requires specific number formatting: + +- Integers: no decimal point (`42`, not `42.0`) +- Decimals: no trailing zeros (`3.14`, not `3.140`) +- No leading zeros (`0.5`, not `00.5`) + +The `Rfc8785JsonCanonicalizer` handles this automatically. + +--- + +## 7. Collection Ordering + +### 7.1 Rule + +All collections that participate in digest computation must have **deterministic order**. + +### 7.2 Implementation + +```csharp +// CORRECT - use FrozenDictionary for stable iteration +var orderedDict = items + .OrderBy(x => x.Key, StringComparer.Ordinal) + .ToFrozenDictionary(x => x.Key, x => x.Value); + +// CORRECT - sort before iteration +foreach (var item in items.OrderBy(x => x.Id, StringComparer.Ordinal)) +{ + // ... +} + +// WRONG - iteration order is undefined +foreach (var item in dictionary) +{ + // Order may vary between runs +} +``` + +--- + +## 8. Audit Hash Logging + +For debugging determinism issues, use the `AuditHashLogger`: + +```csharp +using StellaOps.Attestor.ProofChain.Audit; + +var auditLogger = new AuditHashLogger(logger); + +// Log both raw and canonical hashes +auditLogger.LogHashAudit( + rawContent, + canonicalContent, + "sha256:abc...", + "verdict", + "scan-123", + metadata); +``` + +This enables post-mortem analysis of canonicalization issues. + +--- + +## 9. Testing Determinism + +### 9.1 Required Tests + +Every component that produces digests must have tests verifying: + +1. **Idempotency:** Same input β†’ same digest (multiple calls). +2. **Permutation invariance:** Reordering input collections β†’ same digest. +3. **Cross-platform:** Windows/Linux/macOS produce identical outputs. + +### 9.2 Example Test + +```csharp +[Fact] +public async Task CreateSnapshot_ProducesDeterministicDigest() +{ + // Arrange + var sources = CreateTestSources(); + + // Act - create multiple snapshots with same data + var bundle1 = await coordinator.CreateSnapshotAsync(); + var bundle2 = await coordinator.CreateSnapshotAsync(); + + // Assert - digests must be identical + Assert.Equal(bundle1.CompositeDigest, bundle2.CompositeDigest); +} + +[Fact] +public async Task CreateSnapshot_OrderIndependent() +{ + // Arrange - sources in different orders + var sourcesAscending = sources.OrderBy(s => s.Id); + var sourcesDescending = sources.OrderByDescending(s => s.Id); + + // Act + var bundle1 = await CreateWithSources(sourcesAscending); + var bundle2 = await CreateWithSources(sourcesDescending); + + // Assert - digest must be identical regardless of input order + Assert.Equal(bundle1.CompositeDigest, bundle2.CompositeDigest); +} +``` + +--- + +## 10. Determinism Manifest Schema + +All replayable artifacts must include a determinism manifest conforming to the JSON Schema at: + +`docs/testing/schemas/determinism-manifest.schema.json` + +Key fields: +- `schemaVersion`: Must be `"1.0"`. +- `artifactType`: One of `verdict`, `attestation`, `snapshot`, `proof`, `sbom`, `vex`. +- `hashAlgorithm`: One of `sha256`, `sha384`, `sha512`. +- `ordering`: One of `alphabetical`, `timestamp`, `insertion`, `canonical`. +- `determinismGuarantee`: One of `strict`, `relaxed`, `best_effort`. + +--- + +## 11.

Each CI platform has its own issuer: + +| Platform | Issuer URL | +|----------|------------| +| GitHub Actions | `https://token.actions.githubusercontent.com` | +| GitLab CI (SaaS) | `https://gitlab.com` | +| GitLab CI (Self-hosted) | `https://your-gitlab-instance.com` | +| Gitea | `https://your-gitea-instance.com` | + +### Verification Flow + +``` +β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β” +β”‚ Verification Process β”‚ +β”œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€ +β”‚ β”‚ +β”‚ 1.

"https://git.stella-ops.org" +``` + +## Best Practices + +### Security Recommendations + +1. **Always Constrain to Repository** + + Never accept wildcards that could match any repository: + + ```bash + # BAD - accepts any repository + --certificate-identity "repo:.*" + + # GOOD - specific repository + --certificate-identity "repo:stellaops/scanner:.*" + ``` + +2. **Prefer Branch/Tag Constraints for Production** + + ```bash + # Better - only main branch + --certificate-identity "repo:stellaops/scanner:ref:refs/heads/main" + + # Even better - only signed tags + --certificate-identity "repo:stellaops/scanner:ref:refs/tags/v.*" + ``` + +3. **Use Environment Constraints When Available** + + ```bash + # Most specific - production environment only + --certificate-identity "repo:stellaops/scanner:environment:production" + ``` + +4. **Always Require Rekor Proofs** + + ```bash + # Always include --require-rekor for production + stella attest verify \ + --artifact sha256:... \ + --certificate-identity "..." \ + --certificate-oidc-issuer "..." \ + --require-rekor + ``` + +5. **Pin Trusted Issuers** + + Only trust expected OIDC issuers. Never accept `.*` for issuer. + +### Common Patterns + +#### Multi-Environment Trust + +```yaml +# GitHub Actions - Different constraints per environment +staging: + identity: "repo:myorg/myrepo:ref:refs/heads/.*" + +production: + identity: "repo:myorg/myrepo:ref:refs/(heads/main|tags/v.*)" +``` + +#### Cross-Repository Trust + +```bash +# Trust signatures from multiple repositories +stella attest verify \ + --artifact sha256:... \ + --certificate-identity "repo:myorg/(repo1|repo2|repo3):ref:refs/heads/main" \ + --certificate-oidc-issuer "https://token.actions.githubusercontent.com" +``` + +#### Organization-Wide Trust + +```bash +# Trust any repository in organization (use with caution) +stella attest verify \ + --artifact sha256:... \ + --certificate-identity "repo:myorg/.*:ref:refs/heads/main" \ + --certificate-oidc-issuer "https://token.actions.githubusercontent.com" +``` + +## Troubleshooting + +### Common Errors + +| Error | Cause | Solution | +|-------|-------|----------| +| `identity mismatch` | Pattern doesn't match certificate subject | Check ref format (refs/heads/ vs branch name) | +| `issuer mismatch` | Wrong OIDC issuer URL | Use correct issuer for platform | +| `certificate expired` | Signing cert expired, no Rekor proof | Ensure `--require-rekor` and Rekor was used at signing | +| `no attestations found` | Attestation not attached to artifact | Verify attestation was pushed to registry | + +### Debugging Identity Patterns + +```bash +# Inspect certificate to see actual identity +stella attest inspect \ + --artifact sha256:... \ + --show-cert + +# Expected output: +# Certificate Subject: repo:stellaops/scanner:ref:refs/heads/main +# Certificate Issuer: https://token.actions.githubusercontent.com +# Certificate SAN: https://github.com/stellaops/scanner/.github/workflows/release.yml@refs/heads/main +``` + +### Testing Patterns + +```bash +# Test pattern matching locally +echo "repo:myorg/myrepo:ref:refs/heads/main" | \ + grep -E "repo:myorg/myrepo:ref:refs/heads/(main|develop)" +``` + +## Related Documentation + +- [Keyless Signing Guide](../modules/signer/guides/keyless-signing.md) +- [GitHub Actions Templates](../../.github/workflows/examples/) +- [GitLab CI Templates](../../deploy/gitlab/examples/) +- [Sigstore Documentation](https://docs.sigstore.dev/) diff --git a/docs/guides/keyless-signing-quickstart.md b/docs/guides/keyless-signing-quickstart.md new file mode 100644 index 000000000..811e43542 --- /dev/null +++ b/docs/guides/keyless-signing-quickstart.md @@ -0,0 +1,247 @@ +# Keyless Signing Quick Start + +Get keyless signing working in your CI/CD pipeline in under 5 minutes. + +## Overview + +Keyless signing uses your CI platform's OIDC identity to sign artifacts without managing private keys.

Sprint complete. | Implementer | ## Decisions & Risks -- Decision needed: ASM version for Java extractor (9.x recommended for Java 21 support). -- Decision needed: Babel parser plugins for TypeScript/JSX support. -- Decision needed: Python version support (3.8+ recommended). -- Risk: Dynamic dispatch in Java/Python limits static call graph accuracy. Mitigation: conservative over-approximation, flag unknowns. -- Risk: Node.js dynamic requires are hard to resolve. Mitigation: mark as unknown, runtime evidence can supplement. -- Risk: Large codebases may cause memory issues. Mitigation: streaming/chunked processing, configurable depth limits. +- βœ… Decision made: Java extractor uses pure .NET bytecode parsing (no external ASM dependency needed). +- βœ… Decision made: Node.js extractor uses Babel via `stella-callgraph-node` external tool with JSON output. +- βœ… Decision made: Python extractor uses regex-based AST parsing for 3.8+ compatibility. +- βœ… Decision made: Go extractor uses external `stella-callgraph-go` tool with static fallback analysis. +- Risk mitigated: Dynamic dispatch in Java/Python - conservative over-approximation implemented, unknowns flagged. +- Risk mitigated: Node.js dynamic requires - marked as unknown, runtime evidence can supplement. +- Risk mitigated: Memory for large codebases -

Skipped archival tasks (DOC-DET-08/09) as source files already in appropriate archive locations. | Implementer | ## Decisions & Risks - Decision: Keep "Hybrid Binary and Call-Graph Analysis" separate (different focus). Recommend: Yes, it's about analysis methods not determinism. - Decision: Archive location. Recommend: `archived/2025-12-26-determinism-advisories/` with README explaining consolidation. +- Decision: **Archival skipped** β€” source advisories already reside in `archived/2025-12-25-foundation-advisories/` and `archived/2025-12-26-foundation-advisories/`. Moving them again would break existing cross-references. Added "supersedes" notes in consolidated document instead. - Risk: Broken cross-references after archival. Mitigation: grep all docs for advisory filenames before archiving. - Risk: Loss of nuance from individual advisories.
