I used fcrackzip.

$ fcrackzip -D -p pass.txt -u

-D - dictionary mode, In this mode, fcrackzip will read passwords from a file, which must contain one password per line and should be alphabetically sorted (e.g. using sort(1)).

-p - Set initial (starting) password for brute-force searching to string, or use the file with the name string to supply passwords for dictionary searching.

pass.txt - file containing all passwords

-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. - the zip file on which you want to crack the password
