Access to a computer, several mailboxes, a cloud drive with personal photos, a profile on a social network … Our data is almost everywhere. How to protect them from unauthorized access? The first barrier to use is a strong password. The only problem is that a burglar-proof password is usually associated with an incomprehensible, completely random string of characters that cannot be remembered. But if we create it correctly, only those from whom we want to protect our data will experience problems. It will be completely clear and simple for us. How do you create a password that is strong and hard to crack? This will be discussed in today’s article.
Take as a basis the phrase you know.
If a social network account contains complex and long combinations, then it will be reliable. A competitive intelligence expert gave some tips for creating a password that cannot be cracked. He noted that for reliable protection, it is necessary to create a password that contains numbers and letters. However, there is a problem – the user can forget it himself. To avoid such a case, you need to create a password using known phrases. For example, you can use a part of the phrase from the cartoon “where are we going with Piglet, a big-big secret”, while the number 0 replace the letters “o”, and the letters “a” by @.
In most cases (with the exception of a payment card PIN), when setting a password, we can use the four most important categories of symbols:
- small letters;
- special characters available on a standard keyboard.
Characters from these categories must be included in the password. Why? Again, this greatly increases the complexity of the password and hence its strength and security. The phrase is much easier to remember than random nonsense, since it carries a specific meaning that evokes certain associations.
As a child, you had a goldfish named Mister Bubble. Mr1Pozyr736 is a great password.
Or the sentence “I lived in Germany for two years” can be transformed into “YazhvG2gda” (iliGf2yrs). Even starting with a capital letter, with numbers and random letters in it, it is still vulnerable to brute-force attacks. The same sentence spelled out as the password for “YazhilvGermanyfor2yrs” (ilivedinGermanyfor2yrs) can no longer be cracked. The difference in password length has a large impact on security.
Also, the best password will be expressions of famous people, as well as quotes and aphorisms from films or television series. Model an acronym from a block of easy-to-remember information. For example, use a phrase that symbolizes your child’s birthday on December 12, 2004. From such a sentence, the password will be, for example, Dnms12 / Gr, 4. Change letters or text to numbers, signs and spelling errors in an easy-to-remember phrase. For example, a child’s birthday on December 12, 2004 can be transformed into DNR0zhM0eg0Sun @ 12124 (you cannot use spaces in passwords).
Associate a password with a hobby or favorite sport. For example, I prefer to play badminton can transform into Any # 8B @ dm1nt () n.
If we organize a password consisting only of numbers, we will have only 10 characters (from 0 to 9). Thus, the number of combinations required to crack it is relatively small, especially if the password is of limited length, such as the aforementioned PIN codes for payment cards. For them, the maximum number of combinations is 10,000 attempts. Will this password be strong? Absolutely not.
- Letters but case insensitive passwords are already more secure, but still not secure. To create it, we can use 26 different characters (we take into account the characters available on standard keyboards), the possible combinations in this case are 2 * 1011.
- Passwords, which are still only letters but case sensitive, now contain 52 characters. The number of possible combinations is 5 * 1013. Will this be a strong password? Not yet. He will no longer be weak, but his strength will be average at best.
- Passwords consisting of uppercase and lowercase letters and numbers will be slightly safer, allowing up to sixty-two characters and increasing the number of possible combinations to 2 * 1014. In theory, most of these passwords will be considered strong passwords, but we will soon prove that they do not always have to be strong passwords.
- Passwords consisting of uppercase and lowercase letters, numbers, and special characters (33 characters are available on most standard keyboards) will be much more secure. The 95 different signs we have at our disposal represent as many as 7 * 1015 possible combinations, so we can achieve a really high level of security.
Therefore, it is easy to guess which of the above options should be used. Yes, if we want to create a strong password, it must consist of characters from all available categories.
Try a simple encryption or encoding method
Code and cipher are different concepts: in each code there is a word that is replaced by another, while in the cipher it completely replaces all symbols. There are several types of ciphers that are used to create passwords. Here is some of them:
- ROT1… This is the most popular type of encryption that even children are familiar with. The key is quite simple: each letter changes to the next one in alphabetical order.
- Transpose cipher… The letters in it are arranged according to a certain principle. For example, you can write a word in English and then rewrite it backwards. Another example is swapping all letters. In addition, a columnar cipher can be used, where each character is painted horizontally, and the cipher is created vertically.
- Caesar’s cipher… This is not one, but as many as 26 ciphers, which are applied according to the same principle. The user only needs to remind which step is used for encryption: if ROT2, then A is replaced by B, etc.
An overview of useful life hacks will enable the user to reliably hide their personal data from hacker attacks and fraudsters. A securely generated password guarantees protection against hacking and guessing the key, and the proposed options can be combined at your own discretion. It is enough to just think over the options and use them without fear.
