Claims that white‑box cryptography can keep keys hidden even when attackers control the device, and demonstrates a concrete product: Zkeybox produces a compiled package that implements an RSA unwrap feeding an AES decrypt without exposing the static RSA key or dynamic runtime key in cleartext. Library supports key generation, agreement and derivation, offers C++/Java/JavaScript bindings, runs purely in software, and asserts it resists DSA/DCA/DFA style side‑channel and memory scanning attacks.
