    I've evaluated all of these against each other. One presentation is https://www.nvidia.com/en-us/on-demand/session/gtcspring22-s41620/ (sorry, you have to register - it's not my preference). The performance numbers there are based on code derived from https://github.com/ParRes/Kernels/tree/default/FORTRAN (the code differences are not interesting). Another comparison is found in https://github.com/jeffhammond/nwchem-tce-triples-kernels, which is more complicated in some ways.

    I think the most used is still John the ripper. I don't know how easy it's to use it for your case though, I only tried it many years ago.

    Ok, both John the ripper, hashcat and other tools seem to support extracting the hash, or directly trying to discover the password.

    With the root hash you can crack the root password using tools like John The Ripper[0]. More generally, I assume, this exploit can be used to read any arbitrary files on the system, bypassing regular access control, and plenty of other stuff you aren't supposed to be able to do as a non-privileged user.

    However, most credential brute forcing takes place offline against a leaked database from some site. A program like John the Ripper is used to try hashing each word in a dictionary until it matches the entries in the database. Because this all happens offline, there's no mechanism in place to delay the attempts or lock the user out.

    John the Ripper may also have this ability though IIRC it's not quite as powerful.

What are some alternatives?

When comparing Kernels and john you can also consider the following projects:

hashcat - World's fastest and most advanced password recovery utility

btcrecover - BTCRecover is an open source wallet password and seed recovery tool. For seed based recovery, this is primarily useful in situations where you have lost/forgotten parts of your mnemonic, or have made an error transcribing it. (So you are either seeing an empty wallet or gettign an error that your seed is invalid) For wallet password or passphrase recovery, it is primarily useful if you have a reasonable idea about what your password might be.

mimikatz - A little tool to play with Windows security

bitcracker - BitCracker is the first open source password cracking tool for memory units encrypted with BitLocker

JohnTheRipper - John the Ripper jumbo - advanced offline password cracker, which supports hundreds of hash and cipher types, and runs on many operating systems, CPUs, GPUs, and even some FPGAs [Moved to: https://github.com/openwall/john]

jwt-cracker - Simple HS256, HS384 & HS512 JWT token brute force cracker.

walletool - a tool for reading wallet.dat files

bruteforce-wallet - Try to find the password of an encrypted Peercoin (or Bitcoin, Litecoin, etc...) wallet file.

CrackMapExec - A swiss army knife for pentesting networks

SecLists - SecLists is the security tester's companion. It's a collection of multiple types of lists used during security assessments, collected in one place. List types include usernames, passwords, URLs, sensitive data patterns, fuzzing payloads, web shells, and many more.

Metasploit - Metasploit Framework

SQLMap - Automatic SQL injection and database takeover tool
