Which of the following can be used with John the Ripper to crack passwords?

John the Ripper natively supports wordlist-based dictionary attacks by hashing each entry in a provided wordlist and comparing the result against the target password hash. Wordlists can be combined with mangling rules to extend coverage beyond plain dictionary entries. This is one of the most efficient and widely used cracking modes the tool supports.

Nmap is a network scanning and host enumeration tool used to discover open ports and services, and has no role in password cracking or compatibility with John the Ripper.

Meterpreter is a post-exploitation interactive shell payload within the Metasploit Framework, used after initial compromise, and is unrelated to John the Ripper's hash cracking functionality.

PowerSploit is a PowerShell-based post-exploitation framework designed for Windows privilege escalation and lateral movement, not a wordlist or input source compatible with John the Ripper.
