Extract the release zip, then compile it:

python setup.py build_ext --inplace

On windows you may need to install the Python native development tools from visual studio first.

Then, install the package:

python setup.py install

• As a courtesy to other fans, please refrain from spoiling unreleased story contents if any are found after decrypting.

• An android device with root access (such as an emulator) is required to use this tool.

• Create a new folder at /caches/<platform>/ in the current working directory where <platform> is the localization to decrypt.

(i.e for the japanese release: /caches/jp/.)

• Move the encrypted cache file octocacheevai to the new folder. It can be found at:

\data\data\com.square_enix.android_googleplay.nierspjp\files\octo\pdb\201\<numbers>\octocacheevai

• Create another new folder at /resources/<platform>/ using the same localization as before for <platform>.

Move ALL of the encrypted resources there. They can be found at:

\data\data\com.square_enix.android_googleplay.nierspjp\files\v1\201\.

(In particular, only the ones with 32 character filenames such as c2e196279db8b6a49db81e1a64cd344a are necessary.)

The tool is now ready to be used.

• Example: Decrypting all english resources

reinkuro --localization english --decrypt all

• When run with no arguments, the default behavior is to decrypt the japanese cache and export the differences to json.

optional arguments:
  -h, --help            show this help message and exit
  -d {cache_only,new,all}, --decrypt {cache_only,new,all}
                        Which assets to decrypt. Defaults to cache_only, which will only export differences to json.
  -l {en,jp,encbt,jpcbt}, --localization {en,jp,encbt,jpcbt}
                        Which localization to target. Defaults to jp. Also supports cache files from the closed beta releases.
  -r , --revision       The target cache revision to read during parsing for new assets. Defaults to None.
  -k , --key            Manually specifcy a new key. Hint: Magic alphanumeric numbers.
  -iv , --iv            Manually specify a new iv. Hint: Magic base64-ish numbers.
