NSZ 4.3.0

Hotfix 07.07.2023: If you downloaded nsz_v4.3.0_win64_portable.zip in the first 24 hours after the release please redownload. This fixes #133 (nsz 4.3.0 nsz_v4.3.0_win64_portable won't open).

• Bit-identical PFS0 recreation to comply with the no-intro standard
  • The hash of the original NSP before compression and the hash of the NSP resulting from decompressing the NSZ will match as they are bit-identical.
  • Use the newly introduced --remove-padding option to make existing NSP/NSZ files nxdumptool/no-intro compliant.
  • Use the newly introduced --keep-delta option to keep all useless delta fragments (NDV0) during compression so the NSP (PFS0) can be recreated bit-identical during decompression.
  • PFS0 hash verification is now part of the --verify process. --verify now requires --keep-delta when used during compression or it will detect removed NDV0 fragments as errors. Use --quick-verify to skip the PFS0 hash verification. --quick-verify only verifies NCA hashes and so does not require --keep-delta when used during compression. For compatibility reasons --quick-verify will be automatically used instead when specifying --verify without --keep-delta to match the command line argument and verification behavior of previous NSZ versions.
  • This fixes #98, fixes #101 and fixes #116
• Added console output warning about missing and invalid keys
• Added support for pyinstaller as discussed in #119 (pyinstaller builds for macOS)
• Added crc32 hash of master_key_0f. Thanks to @drizzt for adding it!
