md5 with 500-character long passwords

[pdo]

With hashcat? You don't. Hashcat kernels are largely constrained by what you can efficiently compute on a GPU, and the plaintext limit on the "pure" MD5 kernel is 256 bytes (the optimized kernel is 31 bytes).

Google "mdxfind" for a possible solution to your problem.

i have a wordlist containing possible 500-character long passwords.

yes it is really needed for this challenge.

it seems that

    generatelongpwds | ./hashcat.bin -m 0 hashes.txt

produces no result, even if i test with a long password whose md5 hash is really in hashes.txt

how to work with long passwords and md5 (-m 0)?
