fcrackzip Command Examples in Linux

by Deepika

“fcrackzip” is a command-line tool in Linux-based systems that allows a user to crack the password of a ZIP archive file. This means that it can be used to recover the password of a password-protected ZIP file if the user has forgotten the password or if the password is not known.

fcrackzip uses a brute-force method to try different password combinations until it finds the correct one. It can also use a dictionary attack, which is a method of trying all the words in a dictionary as passwords. It also supports incremental mode that allows to specify a charset and a minimal and maximal length for the password.

fcrackzip Command Examples

1. Brute-force a password with a length of 4 to 8 characters, and contains only alphanumeric characters (order matters):

# fcrackzip --brute-force --length 4-8 --charset aA1 archive

2. Brute-force a password in verbose mode with a length of 3 characters that only contains lowercase characters, `$` and `%`:

# fcrackzip -v --brute-force --length 3 --charset a:$% archive

3. Brute-force a password that contains only lowercase and special characters:

# fcrackzip --brute-force --length 4 --charset a! archive

4. Brute-force a password containing only digits, starting from the password `12345`:

# fcrackzip --brute-force --length 5 --charset 1 --init-password 12345 archive

5. Crack a password using a wordlist:

# fcrackzip --use-unzip --dictionary --init-password wordlist archive

6. Benchmark cracking performance:

# fcrackzip --benchmark
