If you have doubt that the password has a upper case alphabet than replace ‘a’ with capital ‘A’. If you think that your password has both upper and lower case than you can write ‘Aa’. Just like this if you doubt your password has lower case (a), Upper case (A), numeric (1). You have to write there ‘Aa1’.Syntax – fcrackzip –u –D –p Ex – fcrackzip –u –D –p ‘/root/Desktop/dic’ ‘/root/Desktop/Test.zipSo finally we have an all-encompassing command for cracking the password-protected file which should look like this fcrackzip -b -c ‘aA1!’ -l 1-10 -u filename.zip.
