Supports standard formats like JPEG, PNG, and TIFF, and includes basic editing tools like cropping, rotating, and resizing during the loading process.
| Threat | Mitigation | |--------|------------| | | Use Ed25519 signatures that can only be created with the private CA key, which is stored offline in an HSM. | | Key sharing across machines | Bind per‑machine keys to a hardware fingerprint; enforce strict constant‑time comparison. | | Replay attacks | Include a nonce and timestamp; revocation server tracks usage patterns. | | Reverse‑engineering of the validation routine | Apply compiler‑level obfuscation (LLVM‑obfuscator), split verification across multiple functions, and employ anti‑debug checks. | | Man‑in‑the‑middle on activation | All server communication uses TLS 1.3 with certificate pinning; the client validates the server’s public key fingerprint at build time. | | Tampering with stored token | Store token in encrypted OS‑level vault; verify integrity on each read. | | Side‑channel leakage | All crypto operations are performed via libsodium’s constant‑time APIs; avoid branching on secret data. |
