These tools require the python cryptography module, installed with pip install cryptography

• three_ds/aesengine.py
  • 3DS AES engine implementation - includes the keyscrambler as well as methods to get the needed keys from boot9/OTP.
• three_ds/nand.py
  • NAND backup manipulation classes - for NAND image, NCSD header, MBRs.. etc
  • Also handles all crypto required via AESEngine.
• three_ds/crypto_wrappers.py
  • Just wrappers around cryptography.
• nand.py
  • Can list NCSD partitions, extract partitions (twln/twlp, ctrnand, firm0/1, agbsave) and create a NAND backup given those partitions.
  • Requires OTP and NAND CID.
• otp.py
  • Tool for OTP encryption and decryption.
• content.py
  • Tool for working with SD&NAND contents. Generally requires a full path for all the files.
  • Requires either full movable.sed or just the keyY (obtainable via seedminer?)

If no arguments are passed, these tools will look in either %appdata%\3DS\ on Windows or $HOME/.3ds/ on macOS/Linux for the files required.
