Long hash from a large file

[Snoopy]

yeah for sure, thats the preferred way after all (attacking hundreds or thousands of hashes simultaneously would be otherwise impossible), all you need is to get rid of the extra JtR infos like filename etc, see https://hashcat.net/wiki/doku.php?id=example_hashes on what is really needed for a particular hash

but be aware, zips or rars nowadays could produce hashes which are way to long for cracking

can you provide the link to that thread? i dont think this is possible (splitting file)
