Prod.keys Direct

Nintendo uses a hierarchical key system. At the top are master keys (often called "prod keys," short for product keys ). These are the master decryption codes for the console. The prod.keys file is a plain text file that contains a list of cryptographic keys specific to a retail Nintendo Switch console ("prod" stands for "production" or "retail," as opposed to dev.keys for development units).

By following this rule, you stay on the right side of the law, avoid malware, and respect the work of developers (both Nintendo's engineers and the emulator creators who refuse to facilitate piracy). Emulation is about preservation and playing your legally purchased games on better hardware. Treat prod.keys as the sensitive, private key it truly is. prod.keys

This is why official emulator projects like Ryujinx (which shut down after a settlement with Nintendo) and the now-defunct Yuzu included prod.keys with their downloads. They also could not provide links to get it. The emulator software itself is legal (reverse engineering for compatibility is often protected). But distributing decryption keys is not.
