Topic: How long would take to break a 13 character password - page 2. (Read 4866 times)

Nobody should trust these websites because if their database or something else gets hacked then your password can be leaked.

OP I think that you and everybody else should not worry about the length of the 13+ chars password because can't be bruteforced as it will take so much time.

But we should be worried about our security because for a keylogger the password length doesn't matter to log.

Latest news on TOR browser security advise websites says that MITM attacks were responsible for some hacking of some users but that flaw that permitted this attack was patched within 1 day (24 hour) from TOR browser developers.

I am sure I have not any keylogger on my machine yet. That is because no one gives a damn who am I but my question is just in case I need to be safe a 65 characters password which no one has a clue , how safe it is.

How safe it is if someone starts from 0 point trying to hack it, let's suppose he only have the RAR file and nothing else, doesn't know the source nor he does know what this file contains ? I think I am far ahead of the game now but need a confirmation from someone who has dealt with security day to day, someone who has worked at this field.

Hah yeaah If they have a keylogger the whole thing happens to be a hella more easier

Just remember these passwords do not need to be brute forced with a massive database, if the hacker can manage to successfully apply

a Keylogger or even a "Man-in-the-middle" attack.    .... The effort in doing that, is a lot less than having to brute force a massive

password. In any way, no password being used on several different sites are bullet proof against attacks... It just makes it easier for a

hacker to find exploits on ANY of those sites, to get to your password. Use different passwords for different sites, and you will be a bit

more secure.  

Wifi has the weakest protocol to brute force it. If a single person with a Kali Linux installed within your reach it would take this program included there called aircrack ng about 24 hours for 2 characters to brute force so 4 days to a 8 character password.

However I am talking about one of the most secure encryption methods today which is .RAR or .7zip.

How come not a single cracker on this forum yet ?

it would depend on the way of cracking the password. my friend and I were interested how long it wouldtake for a programm to crack our wifi pass using brute force... It took it almost 5 days, password was 8 characters long.

10 numbers and 5 signs and 50 letters, total of 65 characters. Algorithm used is of 7zip or Rar from the Ubuntu Linux which is one of the hardest to crack if you start from zero, especially if they don't know nothing about your password.

Now I have created a password with 2 sentences that makes sense only to me and have put numbers and signs that makes sense only to me. I guess this is the safest as it can be.

It is hard to say as it depends on how many numbers and signs it have

Ok thanks everone for your help. Based on what I have read here I think I have understood what I have to do now. These 2 words together makes sense only to me and no one else in the face of earth (101% sure about this). What if I repeat this password 5 times and make it a 65 character long password and I change these 2 words and number sequences 3 times in the password and 2 times I keep it like that ?

How much would take to crack a 65 character long password made with .RAR Linux Ubuntu algorithm ?

13 characters password is not that easy to hack. It may take a day or more if the password have numbers on it. Using bruteforce on it will take some time to crack the words that you put in your password but it will take a longer time on the number since it is not that easy to crack the sequence of the number. Since bruteforce trying all the common passwords that is in it's program it will be hard to crack the two words that you've put in you passwords since the other one is not in english.

first of all that link you posted is from a question that was asked 3 years ago and although there is not much changed but still it is kind of old.

also as it is also said there it depends on the algorithm used to create the the password hashes (in case it is used) so it may take a lot longer than that.

Length is really the one factor that matters regarding password strength so using more character would be take more time to crack it.

As per this link, with speed of 1,000,000,000 Passwords/sec, cracking a 8 character password composed using 96 characters takes 83.5 days

1,000,000,000 Passwords/sec => Typical for medium to large scale distributed computing, Supercomputers.

Just make sure that you're using 96 charaters password with 13 char, I'm sure even with Super Computer , it still need many years to crack it up

It will take so many time you really have to be lucky to do it,that's the only hope.Computers are really powerful,however a 13 character password provides many possible combinations

As I already posted, it would be (52¹⁰ * 1,259,712) divided by the number of password attempts per second. That can further be decreased by getting more hints about your password. For example, knowing if you only uppercase or lowercase letters would decrease the possible combinations by a factor of 1,024.

Depends on which character is used in the password (small or big alphabets, number, special character, etc), speed of your computer, which encryption is used and hints for the password as well.
But, usually it took very long time if you don't know hints for the password.

The government where I live in is not allowed to put you a gun to your head to find your password. I am talking about a normal government which if they can't hack your password cannot put you into jail.

So what is the approximate time if they have these AMD GPU-s you are talking about ? That's my main concern of this whole thread, an approximate with the latest equipment of a state (It's a good thing for me my state is not so well developed in this category)

Suppose the Russian government wants your password. Cracking your password is not necessary. They put a bug in your computer, your house or put a gun to your head. You can't stop a state.

I tried those websites with a different 14 character passwords as I don't want to put mine online even if they say the password is not registered to their servers and the answers were pretty good.

First website answer:

It would take 1 computer to crack it a quadrillion years

Second website

Your password is strong and secure and it would take 1328957638 years to crack it

Any approximate time needed to crack this password let's say from state sponsorship with 5000 cluster computers ? (cluster PC are with a tons of GPU-s each for cracking)

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.





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