How to set a perfect password Apr 12, 2018

Humans invented the computer and invented the Internet. In fact, it has already announced the death penalty for the perfect password.


A recent study shows that 1% of passwords can be guessed within 4 times. How can it be? simple! Try the 4 most common passwords. Password, 123456, 12345678, and qwerty, which opened the door to 1%.


Well, you are one of those 99%, but do you understand the capabilities of hacking software? Take the free hacking software John X (anonymous) as an example. It can help you test millions of passwords every second. Take a more professional anonymous business software dedicated to the criminal investigation field, claiming to test 2.8 billion passwords per second...


Our password ran in the face of hacking software. It was just a matter of time.


In the beginning, cracking the software would exhaust some of the popular password tables, followed by the entire dictionary, including all common names, nicknames, and pet names. Now, most netizens have learned to add numbers, punctuation, and capitalization to our passwords. This is called "mangling." In theory, this can make passwords harder to guess, but the effect is far from good. You think of the "failsafe" approach. Others and hackers can also think of it. Moreover, the reality is not like this:


The website requires that there must be a number in the password, and the frequency at which the password becomes either password1 or password123 will definitely make it hard for you to look at it. And requiring you to capitalize the password that appears at the same time will produce Password or PaSsWoRd. There must be special symbols for password! and p@ssword.


Forced reorganization seems to be responsible, but you cannot prevent this from happening. Do not be stupid enough to do that stupid thing? It's a pity to tell you that even if it were a "complex" point, it was streaking in the face of hacking software. It was only a couple of frames longer than other people streaking.


Can't remember what is the safest?


Perhaps it is, at least to the extent that it is necessary to “write it down” with a pen and look at the law again and again. Although this will be despised, you don't have to worry about it, because sooner or later these people will taste bitter fruit.


Or the phrase you most do not want to listen to and whisper: You can't remember, don't prove that others can't remember, cannot crack it.


What kind of password is safe?


It's simple: a string of completely random characters. Relying on your own brain is impossible to achieve a perfect random, you do not have to torture it, maybe you think of a good, will regret in two minutes: you can think of other people can think of. Can not rely on the human brain, find a computer ah!


Many websites and applications can now provide you with a completely random password with environmental noise data. Too high you do not have to know, baidu search "password generator", tools abound. Of course if you want to try a random password of 1024 bits or more, I'll give you a link: http://www.sexauth.com


Keep this in mind: Random characters are the safest gold standard you can use today. Even if everyone in the world chooses this solution, it is still safe and reliable.


To make a calculation, there is a combination of uppercase and lowercase letters and numbers. There are 62 different characters (no special symbols, as some sites do not allow it). This means that an 8-bit random password needs to be guessed 62^8 times to ensure a hit, which is to guess 22 trillion times, and this is enough to let you resist the attack, test the patience of the hackers, even if they have the above said Pieces of criminal investigators that can test 2.8 billion passwords per second can guess that the results will take 22 hours. The real hacker encounters this kind of situation, most will directly choose to give up and look for the next goal.


Tip 1: (Reverse) Phrase Method

The most practical and effective technique in common techniques is to turn a phrase or sentence into a password. Pick a word, a phrase, or a lyric, using their initials as a password. Chinese and English are a principle, for example, take the above "fish and bear's paw can not have both", yhxzbnjd, random enough, not good? Add a number, capitalization, reverse the order?


In fact, the above is just an example. The "phrase" here should be the more random sentence. For example, the dialogues that have touched your movie and the sentences on the Internet that express petty bourgeois feelings. Rest assured, even if it is not unique, it is less than ordinary.


An ideal password scheme will not fail even if everyone is in use, but the problem is that once it is popular, it will enter the password dictionary and even the common password list. So don't expect to have a perfect and ideal password program forever. What we can do is try to get close to it.


But the password itself is not so unique, it is not so sure. The acronyms for different sentences may also be the same, yielding the same abbreviated password. Some letters are easier to be the first letter of a word, and hacking software can use this feature.


Tip 2: Protect important accounts with strong passwords


Given the importance of passwords in our lives, it is still worthwhile to remember a random string. Can you remember your ID number, cell phone number, parents' and girlfriend's birthday, and why not remember a stronger password that is related to your privacy or even your property?


However, problems have arisen, various websites, various bank cards, and various types of accounts. Everyone knows the "one-time password" principle, but who can guarantee to put so many random strings into the brain, unless you are also talented.


At this time, you must give up something, just like life. So, decisively give strong passwords to accounts that are important to you. As far as the others do not matter, go with them, but be sure to remember that you can't relate to your strong passwords. Of course, if you are interested, you should sort out your account as soon as possible and classify them.


Tip 3: Beware of "Get Password"


There are also some thieves who will skip over the input password and they will directly answer the security question “Retrieve password”. If you happen to be "masked" by them, the consequences will be clear to you.


In response, there has been a recent report touting a coping strategy: useless answers. For example, you use irrelevant phrases to answer questions, or answer all questions with the same nonsense answer. This method may be temporarily effective, but if one day many people use this method, then it may also fail - your choice of "irrelevant" is likely to be related to other issues.


The last question is even more obvious: weak passwords, which means that your answer is too simple. Do you know what this situation is like? It's like you have opened a back door for your account.


In addition, the most commonly used "recover password" method is an e-mail, and you will find that the vast majority of account registrations now use the e-mail address directly as the ID, and it is not practical for each account to correspond to an e-mail address. , so the e-mail password security level is also obvious, this time decisively show your strong password.


Tip Four: Stop using weak passwords


You may have already guessed what I'm going to list: birthday, ID number, credit card number... These numbers are usually in your wallet. Of course, the bank card is also listed. So once, if, in case, I’m If you say that your wallet is lost on some day, it is estimated that you would like to die.


If you guessed it, most of the time you used to use or are still using these passwords. There are no regrets drugs in the world, 110 to find the police uncle? Oh, if you want to.


I know that many of my friends will complain about too much nonsense, but I want to say is that maybe you are not in this queue, but you do not believe that until now, there are many people in the world knowing that they are using weak passwords. "Too lazy to modify". This is human inertia.
