The Yuzu emulator was engineered as a high-level emulator (HLE). It simulated the Switch's hardware environment and re-implemented the functions of Horizon OS in C++. However, Yuzu did not contain Nintendo's proprietary decryption algorithms or the actual cryptographic keys within its source code. Including these keys would have constituted a direct copyright violation from the inception of the project. yuzu prod keys

(short for Product Keys ) are a specific set of cryptographic keys unique to the Nintendo Switch's hardware and firmware. They are stored deep within the console's internal memory (specifically in the TSEC and Secure Monitor). When the Switch boots a game, it uses these keys to decrypt the executable code in real time.
