A versatile PC utility available on GitHub used to patch, split, merge, and convert Switch game files (e.g., converting XCI to NSP or decompressing NSZ).
To perform almost all of these functions, . Without a valid prod.keys file placed in its root folder, SAK cannot decrypt, compress, or convert your game files. Understanding keys.dat, prod.keys, and title.keys
This file pairs with specific games to authorize and decrypt individual titles. sak are the keysdat prodkeys correct 2021
In 2021, several major software vendors—including Magix (owners of Vegas Pro) and Adobe—migrated to and hardware ID (HWID) binding . This rendered static .keysdat -based cracks obsolete. Previously, a single "prodkey" could activate offline copies; after 2021, vendors implemented:

Keys are backward compatible. A 2021 key file will perfectly decrypt games released in 2017, 2018, 2019, and 2020. Understanding keys

In legitimate software, .keysdat files are rarely used. However, in the world of software cracking, .keysdat files became known through tools (like UKeygen or Enigma -based generators) that store precomputed product keys or cryptographic salts. The keysdat file acts as a local database that a crack or loader reads to trick a program into thinking it has a valid license.
: In many instances, this is simply a renamed or alternate format of the standard keys.txt or prod.keys required by certain custom firmware variations and applications. Why 2021 Keys Are No Longer Correct
