name: crypto-testing
type: domain
description: "Tests cryptographic implementations against known attacks and edge cases using standard test vectors and timing analysis. Covers vector formats, result flags, and reading a failure. Use when auditing crypto code for correctness or timing leaks, checking a library against standard test vectors, or investigating why two implementations disagree on the same input."

# Cryptographic Testing

Cryptographic code requires specialized testing beyond standard security scanning.
Subtle bugs in crypto implementations can completely undermine security.

## Background

### Key Concepts

| Concept | Description |
|---------|-------------|
| Test vector | Input/output pair for validating crypto implementation |
| Timing attack | Exploiting execution time variations to extract secrets |
| Constant-time | Code that executes in same time regardless of secret values |

### Why This Matters

Cryptographic bugs can:
- Expose private keys
- Allow signature forgery
- Enable message decryption
- Leak secret values through side channels

## Quick Reference

| Scenario | Recommended Approach | Skill |
|----------|---------------------|-------|
| Validate crypto primitives | Wycheproof test vectors | **wycheproof** |
| Check for timing leaks | Constant-time analysis | **constant-time-testing** |
| Fuzz crypto parsers | Coverage-guided fuzzing | **libfuzzer** |
| Find edge cases | Property-based testing | **property-based-testing** |

## Testing Workflow

\```
Phase 1: Static Analysis      Phase 2: Test Vectors
┌─────────────────┐          ┌─────────────────┐
│ Identify crypto │    →     │ Run Wycheproof  │
│ Tool: semgrep   │          │ Tool: wycheproof│
└─────────────────┘          └─────────────────┘
         ↓                            ↓
Phase 4: Fuzzing              Phase 3: Timing Analysis
┌─────────────────┐          ┌─────────────────┐
│ Edge case bugs  │    ←     │ Side-channel    │
│ Tool: libfuzzer │          │ Tool: CT tools  │
└─────────────────┘          └─────────────────┘
\```

## Tools and Approaches

| Tool/Approach | Purpose | Complexity | Skill |
|---------------|---------|------------|-------|
| Wycheproof | Validate implementations | Low | **wycheproof** |
| Constant-time tools | Detect timing leaks | Medium | **constant-time-testing** |
| libFuzzer | Find edge case bugs | Medium | **libfuzzer** |

### Wycheproof Test Vectors

Test vectors cover ECDSA, RSA, AES-GCM, ECDH, and more.

> **Detailed Guidance:** See the **wycheproof** skill for setup and usage.

#### Quick Start for Crypto Testing

\```bash
git clone https://github.com/google/wycheproof
# See wycheproof skill for integration patterns
\```

### Constant-Time Analysis

Essential for code handling secrets.

> **Detailed Guidance:** See the **constant-time-testing** skill for tools and techniques.

## Common Vulnerabilities

| Vulnerability | Description | Detection | Severity |
|---------------|-------------|-----------|----------|
| Timing side-channel | Execution varies with secrets | constant-time-testing | HIGH |
| Signature malleability | Multiple valid signatures | wycheproof | MEDIUM |
| Invalid curve attack | ECDH with bad points | wycheproof | CRITICAL |
