I have .rar file that is password protected, but I accidentally have forgotten the password. The file extremely important to me.

How can I get my file back? In windows, there was many programs that could remove the password of such a file. Is there one for Ubuntu?

I would say find some of those programs and run them under Wine. I'm not sure if you've ever tried this process before, but it takes a VERY long time to complete. I wish you luck in recovering those files! I know that pain...It's almost tragic :(

frcackzip is also one of the password cracker. It can do bruteforce attack also. sudo apt-get install fcrackzip

can install that.

usage: fcrackzip -u -c aA1 -l 4-6 secret.zip

  • The -c option lets you select the characterset, 'a' here means lower-case alphabets(small letters).
  • The -p option lets you select an initial string to start brute-force attack.
  • If you run fcrackzip without the -u option then it will throw a lot of possible passwords. When used with -u, it will try to decompress the file with those possible passwords, thus letting you know the exact one.

  • aA1 are indicating that smallcase, uppercase & numbers will include in search.

  • If you'd lile to include sepcial char also then you can go for ! .I mean it will be now aA1!
  • -l stands for length , 4-6 letters.

cRARk has a linux client - I've never had the patience to run it, but you might have some luck.
