HSM Fuzz Testing

Fuzz testing orchestration for HSM modules.

Usage

/hsm-fuzz <module-number> [iterations]

Default iterations: 1,000,000

What You Do

1. List Fuzz Targets:

``bash cd crates/<module> cargo fuzz list ``

1. Run Fuzz Tests:

For each target: ``bash cargo fuzz run <target> -- -runs=<iterations> ``

1. Monitor Progress:

Show real-time stats: - Runs completed / total - Crashes found - Hangs detected - Coverage achieved

1. Handle Crashes:

If crash found: ```bash # Minimize corpus cargo fuzz cmin <target>

# Minimize crash cargo fuzz tmin <target> crash-<hash> ```

1. Report Results:

`` Target: fuzzed25519verify Runs: 1,000,000 Status: PASS ✅ Crashes: 0 Coverage: 94% ``

Common Fuzz Targets

• Crypto Engine: sign/verify, encrypt/decrypt
• gRPC API: request parsing
• Audit: event serialization
• Storage: encryption/compression
