How long wpa passphrase

You can do this in a couple of ways:. These last two options are a lot friendlier to people who need to use your Wi-Fi network.

My current network password is a character random ASCII string and my friends have complained bitterly. While picking an impossible-to-type passphrase will mean that your network is more secure since nobody can use it , most people wish to actually use their computer systems, so it's important to balance security and usability.

This is probably the most important thing to remember about security in general. Sign up to join this community. The best answers are voted up and rise to the top.

Stop thinking of randomized long passwords, and start thinking of pass phrases. Choosing 6 random words out of a dictionary and combining them is A.

Faster to type B. Add a comment. A good number of Wi-Fi access points are protected with passwords consisting of exactly 8 digits. While this attack takes longer than trying the list of local phone numbers, it may be worth running depending on your computational resources. A single video card will crunch through these all-digit passwords in under three minutes, making it worth a try. Wi-Fi passwords are meant to be shared and used by a number of people.

More often than not, these passwords are made to be easy to memorize and easy to type, especially on mobile devices. As a result, many passwords are based on combinations of one to three dictionary words, some numbers, and very few special characters.

In other words, we recommend using automatically adjusted dictionary attacks when auditing Wi-Fi passwords. If a wireless network can withstand a GPU-assisted dictionary attack with mutations during a given timeframe, one can consider the network to be secure. Every year, millions of user accounts are compromised, and millions of passwords are leaked.

We strongly recommend obtaining the list of the most commonly used passwords such as the Top 10, passwords or Top 10 million passwords, and run a simple, straightforward attack through the dictionary of leaked passwords. The dictionaries of the most common passwords can be obtained from GitHub.

Wi-Fi passwords frequently contain one or more words in natural language. You can often recover such passwords by running a dictionary attack. A dictionary attack against a Wi-Fi password requires one or several dictionaries; a dictionary of English words is a good starting point, but dictionaries of local languages should not be forgotten. Sometimes, the among of modifications is just enough to pass the enforced security policy.

He has been able to connect with this on a number of computers, but when stepping him through it with Ubuntu we found that Network Manager imposes a strict limit of 8 or more characters. Before I fire off a bug report, I would like to know: is that 8 or more character limit a hard, technical limit and the guy on the phone just crazy , or is it indeed possible to have a WPA key with 7 characters?

The limit of 63 comes from the desire to distinguish between a pass-phrase and a PSK displayed as 64 hexadecimal characters.
