As others have pointed out, you can't reverse the hash(), but hackers have started using something called rainbow tables, which are huge indexes of stored hash values, to compare hashed values against as a shortcut in the process. By searching the rainbow tables, you can find possible matches to your hashed value and so find what the original string might be.
Having said that, the way I understand it, a hash is 32-bit, so there are finite number of possible hash values. I believe the end result is that it is possible for a single hash to represent more than one string. So you might find your hash in the rainbow tables, but the original string still might not match. >is there any possiblity to reverse the hash() > >I have a value 1xc231vx231cx2v1x2cv132xc1v23 thats hash, how can I >revert back into the normal text. > >Thanks > >-- >Regards, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Find out how CFTicket can increase your company's customer support efficiency by 100% http://www.houseoffusion.com/banners/view.cfm?bannerid=49 Message: http://www.houseoffusion.com/lists.cfm/link=i:4:206007 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
