Ok, i wasn't active for a bunch of years, but really cant watch You guys struggling. So i'll do some math for You.
Taking into account that the password is only alphanumerical characters of various cases (which we know is not but we'll get to that later), that gives us 62 letters/numbers to work on.
If we assume that the password is only 8 letters (again, which we dont know but we assume it's longer but to that calculation 8 letter password is enough to bring my point to the light). That gives us 218 trillion combinations. Yes, Two hundred eighteen trillion combinations. Don't know what trillion is ? Check google.
Assuming we have one of most powerfull standalone machines in the world (because password crackers that we know of cant work on clustered environment, and unless we write our own it's pointless to search for one) we can afford "class C" bruteforce attack. We would crack the password in just 7 years. Yupieee !
But, if we take into account that it's chinese language that we are working with, we would have 8 quadrillion (again, google it) operations with just 4 letter password. Giving us an unnamed number of combinations with 8 letter. A supercomputer capable of few million operations per second would crack the password in 22000 years.
So yea, Mental, no offence. It's possible. Just not in this quantum state of technology. Not in our lives.
Either we know the password, or we can forget about the file
Cheers
