The issue @KJIsaacson is how strong was your Master Password in your LastPass vault - was it high entropy (i.e. random to some degree - the more the better) and long...? If not then there is a fair chance your particular vault may get cracked eventually - whether that's already happened or might happen in 3, 9, 19 months is hard to say... BUT that is only if yours is one of the ones lost - it might not be and you may have nothing to worry about.
Check out the table below - this assumes reasonable entropy (randomness) - so if you used very common words or people's names, etc, it will be quicker to crack. You should aim to be "in the green" with your password (it's easier to do this with passphrases than passwords).
Also, regardless of the length or complexity of your password, if someone else on the planet just happened to choose it as well, and it just happened made it into a password breach list, then time to crack drops to near-zero.
Most of these factors affect what is called entropy which has not been mentioned. There are sites which will calculate the entropy of a password for brute force cracking versus dictionary, rainbow table, or user profile. (Despite the disclaimer that what you enter doesn't go anywhere:
A good analogue way to generate passwords yourself physically is to use The Diceware Passphrase Home Page and 1 or more normal 6-sided die/dice. So very tactile. Basically make 5 dice rolls in succession so you generate a 5-digit number (like 34523) and then look it up in the full list of words (there are some alternate lists on the site too). You do this 4, 5 or 6 times to get your words in sequence (depending how long you want your passphrase to be) and then just put a (different) random number or symbol (or otherwise a dash) between each one to complete a contiguous string. This will give you as good a random high entropy (but memorable) passphrase as you can get. Obviously you'd normally just do this for the few key things (like your 1PW Master Password/Passphrase), but you could do it to generate all your passwords...
For the Omni calculator, also take a read of the 'Password entropy is NOT all that matters' section. A password/passphrase could have high entropy, but could also appear in leaked/online dictionaries - which would effectively make the entropy zero!
A password that is already known has zero bits of entropy. A password that requires at most 2 guesses to find has 1 bit of entropy. A password with n bits of entropy would require 2^n guesses to guarantee that password will be found. For some context, it's realistic that a normal person with a single graphics card on their computer can guess about 2^49 passwords per day. Someone with a data mining system might be able to get 2^55 passwords or possibly more, depending on their hardware. (Note: these numbers are based on GPU hash breaking and require a data dump of password hashes. Web based brute forcing would be much slower.)
and entropy must always increase, a system within the universe would always be at a temperature lower than its surroundings and hence could experience heat transfer which would mitigate the absolute zero condition.
The most common nouns and verbs were only counted if they appeared in the top 1,000 nouns and top 1,000 verbs used in everyday English. Otherwise the lists would have been full of nouns like password and verbs like love.
The 1Password Secret Key may not be the most user-friendly aspect of our human-centered design, but it means that we can say with full confidence that your secrets will remain safe in the event of a breach.
This comic says that a password such as "Tr0ub4dor&3" is bad because it is easy for password cracking software and hard for humans to remember, leading to insecure practices like writing the password down on a post-it attached to the monitor. On the other hand, a password such as "correct horse battery staple" is hard for computers to guess due to having more entropy but quite easy for humans to remember.
xkcd's password generation scheme requires the user to have a list of 2048 common words (log2(2048) = 11). For any attack we must assume that the attacker knows our password generation algorithm, but not the exact password. In this case the attacker knows the 2048 words, and knows that we selected 4 words, but not which words. The number of combinations of 4 words from this list of words is (211)4 = 244, i.e. 44 bits. For comparison, the entropy offered by Diceware's 7776 word list is 13 bits per word. If the attacker doesn't know the algorithm used, and only knows that lowercase letters are selected, the "common words" password would take even longer to crack than depicted. 25 random lowercase characters would have 117 bits of entropy, vs 44 bits for the common words list.
Sometimes this is not possible. (I'm looking at you, local banks with 8-12 character passwords and PayPal) If I can, I use a full sentence. A compound sentence for the important stuff. This adds the capitalization, punctuation and possibly the use of numbers while it's even easier to remember then Randall's scheme. I think it might help against the keyloggers too, if your browser/application autofills the username filed, because you password doesn't stand out from the feed with being gibberish. 188.8.131.52 09:01, 30 August 2013 (UTC)
And that's why it is stupid to explain this kind of joke : it depends on many (MANY) parameters such as brute-force method and encryption/hash algorithm. Giving this kind of (wrong) explanations about "pass cracking" (as if it was always the same way to process ...) is ridiculous. And they talk about entropy .......... Holy shit, go back to school and stop screwing cryptography up. zM_
Originally I logged in to report a local xkcd related phenomenon, and ask if anyone else had experienced it. The destiny, seemingly inescapable, that at once became my own upon seeing that last panel; the effect of the self-fullfilling combination of the very specific look of inquiry -- one I recognize immediately and associate with the words "interesting, Captain" -- and the insidiously performative "You've already memorized it." At first I doubted this was actually the case, but soon I could no longer, since not only did the phrase readily come to the mind and out the mouth, it also came up often. The "correct" soon replaced the word "right" in everyday conversation, then "right you are" and "yes" and so forth, then its opposite (with a "no" in front), then replacing the direction, the verb involving pen and paper (the most recent development was merely a quick under the breath aside of an acronym of the remaining words). All followed by the rest of the absurdly perfect password. Now here's the kicker: I logged on to tell you all this for some reason, only to find, I had memorized "correct horse staple battery" instead of "correct horse battery staple."A female faust (talk) 03:58, 31 July 2016 (UTC)
There is one aspect which has been left out the whole time. I do not question things like wordlist length, entropy, or substitutions. However, doing shoulder surfing will either reveal a full password or in parts. A full password should not be topic of discussion. In the case of partial success, it is in the proposed method far easier to guess the rest of the password than in the traditional one. CommingFromTheSide (talk) 15:16, 5 November 2019 (UTC)
An adversary has to be within range of both the client being attacked (meaning the smartphone or laptop) and the network itself.This means an adversary on the other side of the world cannot attack you remotely.However, the attacker can still be relatively far way.That's because special antenna can be used to carry out the attack from two miles to up to eight miles in ideal conditions.Additionally, the attacker is not competing with the signal strength of the real Wi-Fi network, but instead uses so-called Channel Switch Announcements to manipulate and attack the client.As a result, it is possible to successfully carry out attacks even when far away from the victim.
Users share a lot of personal information on websites such as match.com. So this example highlights all the sensitive information an attacker can obtain, and hopefully with this example people also better realize the potential (personal) impact. We also hope this example makes people aware of all the information these dating websites may be collecting.
Now, this might look a bit complex and, indeed, the mathematics does take a lot of computer power given the large size of the numbers; since p and q may be 100 digits (decimal) or more, d and e will be about the same size and n may be over 200 digits. Nevertheless, a simple example may help. In this example, the values for p, q, e, and d are purposely chosen to be very small and the reader will see exactly how badly these values perform, but hopefully the algorithm will be adequately demonstrated:
Figure 13 shows a PGP encrypted message (PGP compresses the file, where practical, prior to encryption because encrypted files have a high degree of randomness and, therefore, cannot be efficiently compressed). In this example, public key methods are used to exchange the session key for the actual message encryption that employs secret-key cryptography. In this case, the receiver's e-mail address is the pointer to the public key in the sender's keyring; in fact, the same message can be sent to multiple recipients and the message will not be significantly longer since all that needs to be added is the session key encrypted by each receiver's public key. When the message is received, the recipient will use their private key to extract the session secret key to successfully decrypt the message (Figure 14). 2b1af7f3a8
