🖥️ HSM Simulator

A fully interactive Thales payShield 10K simulator with:

• 111 console commands implemented — the same commands you'd run on a real HSM
• Physical key simulation — turn keys to switch between Online, Offline, and Maintenance modes
• Smart Card reader — 4 card slots, insert/remove cards, load LMK sets
• Real response codes — authentic payShield error codes and behavior
• Host commands — Easy and Real mode for learning and production simulation

Perfect for learning, training, development, and testing — without needing access to a real $50,000+ HSM.

🔒 Security

• All cryptography runs client-side — your keys and data never leave your machine
• Content Security Policy (CSP) enforced
• Context isolation and sandboxed renderer
• Secure credential storage via OS keychain (safeStorage)
• No telemetry, no tracking, no data collection
• Auto-updates via GitHub Releases (signed)
