hawk007 Posted October 14, 2015 Share Posted October 14, 2015 Sorry, no way man. Bruteforce attack is the last resort. But, depending on the key length, it might take even million of years.But...if you have used commonly used word as the "passphrase" then Dictionary Attack may helpful to recover this in short time. Elcomsoft have few tools to do that. Please search the forum for this. Link to comment Share on other sites More sharing options...
A.lemane Posted October 14, 2015 Share Posted October 14, 2015 a super computer would door at least a pc with insanely strong GPU because some Bruteforce softs use GPU to compute aloooooot faster Link to comment Share on other sites More sharing options...
andy2004 Posted October 14, 2015 Share Posted October 14, 2015 If its a file you downloaded. try googling the filename, look in your browser history you may still find the link for the download. Link to comment Share on other sites More sharing options...

dcs18 Posted October 14, 2015 Share Posted October 14, 2015 You can try uploading the file to some download host and share the link, here — people could then try cracking the file, for you. :think: Link to comment Share on other sites More sharing options...
