Thank you but let me tell you a bit more about it so you can give me a more accurate explanation (this one is accurate enough but I want to add a little info here)

My password consists of 2 words 1 is in English 1 is in another language there are 2 numbers and 1 special character in the end.

I have tried in a website which calculates how much is needed to crack it (the RAR) in that website. It says to me that even with 100.000 PC with 500.000 passwords per seconds it needs about 12.000 years and a bit more to crack. I think this is safe, as the computers there are cluster computers and not just 100.000 pc connected to each others.

A cluster computer have a tons of GPU to try to crack your passwords.

I know hackers cannot break it as the maximum they may have is 1,2 or about 20 clusters maximum but state has as many cluster as they want so regarding this is my question.

If this file goes in the hand of a national security agency how long it will take approximately to crack it ? If it is more than 1 month for me is OK, I will transfer my bitcoins to another wallet during this time without problems.

Edit: The English word cannot be found in any dictionary, it's a special word , people use it rarely and I checked a few dictionaries and couldn't find this word there.

There are 2 numbers and 1 special character at the end. You didn't specifically say how those 3 characters were ordered, so I would assume nothing regarding their arrangement. According to this page, I can assume there to be a subset of 98 special characters to choose from. Adding in the 10 digits of the decimal system, that would be a set of 108 characters. So the last 3 characters of your password, if taken separately, would result in a possible 1,259,712 (108 x 108 x 108) combinations.

Assuming that you are correct in your assertion that the 2 words which you used for your password cannot be found in any common word list, then we would be forced to use permutation of the 26 letters of the Latin alphabet instead. Using both uppercase and lowercase letters, the first 10 characters of your password would come from 52¹⁰ possible combinations.

With both parts, the password would have to be tested from a possible (52¹⁰ * 1,259,712) combinations of characters.

How long it would take to brute force through all those would depend on the hardware and software used. If you are wrong and the used words can be found in a word list though, then the time would be significantly decreased.

It's somewhat secure, but it becomes even less so the more hints that you give. Tongue

It is true, There is no safe password because there many tools for cracking algo. But a 13 characters is a very difficult password based on my experience and even a pro hacker without a clue about on your personal info will not gonna make it within a day.

Stop spamming your sig, Captain Obvious. The OP knows all that. That wasn't his question.
