What is encTitleKeys.bin?

encTitleKeys.bin is a database file used primarily by custom firmware (CFW) and homebrew applications on the Nintendo 3DS. Its main feature is to act as a lookup table for the encrypted title keys of games and applications.

1. Place enctitlekeys.bin in /gm9/out/ on your SD card.
2. Use GodMode9’s "Ticket Options" → "Import Encrypted Title Keys".
3. Reboot.

Here is how to do it:

How it Works (Technical Summary)

• Structure: The file typically consists of a header followed by a series of entries. Each entry usually contains the Title ID (identifying the game) and the Encrypted Title Key.
• Decryption Process: When a 3DS with Custom Firmware (CFW) runs a game, the system takes the Encrypted Title Key from the ticket (or generated via this bin file), decrypts it using the console's common key, and uses the resulting Decrypted Title Key to unlock the game content (NCCH format).

: The 3DS uses AES-128 encryption. The Title Keys themselves are encrypted using "Common Keys" stored in the 3DS's SoC (System on Chip). The Database enctitlekeysbin 3ds top
