SecureLink

Extension

Browser extension client with installation proof (Chrome, Firefox, Edge).

pnpm add @securelink/extension

Production defaults

  • Storage: browser.storage / chrome.storage (session preferred) — not page localStorage
  • Installation keypair: Ed25519; public key only registered with the server
  • Per-request proof binding (safe under concurrent calls)
  • Manifest needs the storage permission

    },
  },
});
