7z2hashcat
#25
The original 7-zip file (*.7z) is not needed to recover the password.
But the entire output of 7z2hashcat is needed (the whole hash).

Yes, as mentioned here: https://github.com/philsmd/7z2hashcat#se...ta-warning some hashes generated by 7z2hashcat could in theory contain (encrypted and sometimes compressed) sensitive data.
Unfortunately, this is how the algorithm used by 7-Zip works, it needs to create a crc32 checksum of the data. In general, it's only the checksum of 1 file (in general "the first" file).

7z2hashcat tries to output the smallest amount of bytes possible (i.e. only those bytes that are really needed). The output of 7z2hashcat does not contain any extra bytes or data that could also be skipped/ignored (everything within the hash is needed for hashcat).
