This repository contains all files from https://openwall.info/wiki/john/sample-non-hashes unpacked and somewhat cleaned up.

Normally, the password to crack a sample is included in the file name (e.g. zip1_testpassword#.zip has a password of testpassword#) or in a file near it, such as password.txt which can be used directly as a wordlist.

If all else fails, try really simple passwords including openwall and hashcat. Or if you're lucky, the latest John Jumbo has the sample as a test vector. To dump all such test vectors' passwords to a wordlist, try this:

./john --format=cpu --list=format-tests | cut -f4 | ./unique all_tests.lst
