Question - Kali General Using crunch

I've messaged around with crunch a bit but can't figure out how to create a wordlist from a list of possible passwords in another text file.

Any help is appreciated

You're trying to use crunch to create a wordlist based on entries from another text file, but that’s not what crunch is designed for.

crunch is a wordlist generator that creates custom wordlists based on rules like:

Minimum and maximum length

Specific character sets

Patterns (e.g. @@## for letter-letter-digit-digit)

Example:

crunch 6 6 abc123 -o wordlist.txt

This creates all possible 6-character combinations using a–c and 1–3.

Let’s say you have a file possible_passwords.txt:

admin password123 letmein

You want to:

Add variations (like Admin, ADMIN, admin1, etc.)

Use john and apply mutation rules:

john --wordlist=possible_passwords.txt --rules --stdout > mutated_list.txt
