Request assistance in decrypting files

The npk files in APK can be used https://github.com/zhouhang95/neox_tools/ and nxpk_v0.4.3 can be unpacked
The unpacked file is not a normal engine file, it should be encrypted data
The data below is also an encrypted file

APK里面的npk文件可以使用https://github.com/zhouhang95/neox_tools/和nxpk_v0.4.3进行解包，
解包后的文件不是普通的引擎文件，应该是加密数据，
下面的数据也是加密文件

Your files are compressed by zstd, they can be decompressed, and most of them are texture files of .ktx after decompression. At present, nxpk_v0.4.3.bms should not have written the logic to decompress zstd, so what you get is compressed files and a bunch of messy files. I have little understanding of .bms scripts. The decompression process I completed is using my own python script. In order to perfectly extract, I suggest that they update nxpk_v0.4.3.bms.

zstd is now supported in v0.4.4
