Using a wordlist

❗ The wordlist MUST BE SORTED: sort(1)

cat /usr/share/wordlists/rockyou.txt | sort > rockyou-sorted.txt

WL=rockyou-sorted.txt
ZIPFILE=file.zip

fcrackzip -u -D -p $WL $ZIPFILE

Using generated password

-u: try to decompress the first file by calling unzip with the guessed password.
 This weeds out false positives when not enough files have been given.
-c: lets you select the character set, "1" means password also be numeric.
-p: lets you select an initial string to start brute-force attack.

fcrackzip -u -c <your password character type> -p <total digits> <zip file path>

ZIPFILE=/root/Downloads/file.zip

Lowercase, 6-character passwords

fcrackzip -c a -p aaaaaa $ZIPFILE

lowercase, uppercase, digits, special chars, length 1 to 8 characters

fcrackzip -b -c aA1! -l 1-8 -u $ZIPFILE
