If the encryption is anyway half decent, your PC won't have the processing grunt to do it any-time soon.

Have you thought to do a search for decryption software, lots of hits, but you need to exercise care as there are lots of hits that are considered suspect by WOT and I would imagine Fynian (or whatever it is called now) would also through up sites with dubious rep, etc. The reason I mention this is that rogue software/malware would be targeting this type of search; so only visit known sites or from the major download sites, etc..

our professor has encrypted some data and in a zip file and he is offering extra credits for anyone who can give him the key.so i was wondering if any one here knew / have used any password recovery software.

I've seen such programs for Linux.
