Data layer block(s) failed hash validation error when extracting NCA3 Meta files

I'm getting an error that says [pie::hac::HierarchicalIntegrityStream ERROR] Data layer block(s) failed hash validation
when extracting files of the following type:
[NCA Header]
Format Type: NCA3
Dist. Type: Download
Content Type: Meta
Key Generation: 11
Sig. Generation: 0
Kaek Index: Application (0)
Size: 0xdfe00
ProgID: 0x010096f00ff22000
Content Index: 0
SdkAddon Ver.: 9.6.0 (v151388160)

icon_AmericanEnglish.dat
icon_BritishEnglish.dat
icon_CanadianFrench.dat
icon_French.dat
icon_German.dat
icon_Italian.dat
icon_Japanese.dat
icon_LatinAmericanSpanish.dat
icon_Spanish.dat
Inspecting the files, they all look correct aside from the last one - icon_Spanish.dat
in this case. It's an icon of the game/Title ID but part of it is cut off. The other icons render fine when opened up in an image editor. So it looks like for whatever reason, the length of the last file is calculated wrong when extracted. I'm not sure if it's related to the error message I received above but my guess is that it is.
FYI - I tried extracting other files of this type and same thing - the last icon in the set is cut off.
Let me know if you need me to upload any files. This is the command I used to extract:
./nstool -k prod.keys -x ./nacp/ 010096f00ff22000.bin
Interesting, it looks like NSTool isn't parsing the file system properly. Thank you for reporting this. If you're offering to upload sample data, that would help.
- You can email it to jakcron.dev@gmail.com
- Or reach out to me on discord jakcron#5805
I am getting the same error on a different file (the content type is Control) but it happens after extracting a few files
@jakcron here is 2 samples
Thank you all, the issue was identified by @sagumamugas. There was an issue where reading a partial end block resulted in uninitialised data being included in hash generation.
This should be fixed in the next release.
@relm @Heath123 @martinlindhe Thank you for your patience.
Please try NSTool v1.7.0 (https://github.com/jakcron/nstool/releases/tag/v1.7.0-r2)
