is there a tool to fix nca signature header invalid?

[QuickWick]

Is there some sort of tool to fix an nca header signature issue. I was playing around with SAK and converting files around between different formats (XCZ, NSP, NSZ). On some conversions, I get "nca header signature verification failed with status <<invalid>>" when checking it with NXViewer. Maybe something that allows you to edit it manually to become proper or allows you to repair it?

Hash shows valid for all files.

No. If the data itself is valid, these 'header signature' gives absolutely 0 issues. Forget about them. You don't need to do anything.

No because this requires Nintendo private keys that never leaked.

Thanks for the answer. Just what I was looking for. So confirmed it cannot be done.

Is there possibly something that converts xci to nsp and to nsz's while keeping signature in tact?

XCI and NSP require different signatures, so no.

You can convert nsp to nsz and xci to xcz without breaking signatures

Amazing answer. Bravo. Thank you sir.

i doubt this. afaik, the process to convert from nsp to nsz is
decrypt-compress-reencrypt
because compression works best for unencrypted data.
Therefore the contents are modified and the signature is broken.
Same for xci-xcz.
