```

## Options
```shell
-d / --decrypt          Decrypt hca files
-k / --key <key>        Decrypt key
-w / --awbKey <awbKey>  Decrypt key In Awb File (Default: 0)
-t / --type <type>      Hca Encrypt Type (1 / 0) (Default: 1)
-o / --output <output>  Output Directory / File
-v / --volume <volume>  Wav Volume (Default: 1.0)
-m / --mode <mode>      Wav Bit Mode (Default: 16)

```

## Features

acb2hcas - Extract acb file to hca files (with/without decrypt)

acb2wavs - Extract acb file and convert hca files To wav files

acb_mix - Experimental. Convert acb file (and awb files) to mixed wav files

awb2hcas - Extract awb file to hca files (with/without decrypt)

awb2wavs - Extract awb file and convert hca files To wav files

hca2wav - Convert hca file To wav file

view_utf - Export data in utf format file to json file (acb/acf file)

decrypt_acb - Decrypt acb file (and awb files) (Warning: will overwrite orignal file)

decrypt_awb - Decrypt awb file (Warning: will overwrite orignal file)

decrypt_hca - Decrypt hca file (Warning: will overwrite orignal file)

extract_cpk - Extract cpk file

## Tips

Drop acb/awb/hca files to win_*.bat is easy to use in Windows.

"CriAtomViewer" In "CRI ADX2 LE" can play acb/awb/hca files with encrypt type 1 (encrypt type 0 / 56 is not supported).

Some awb files in pc/web game is encrypted and not supported.
