Generate New Key Wpa From Passphrase 3,6/5 9771 reviews
The data used to generate the passwords is derived from Linux's /dev/urandom secure data source, and is carefully masked to prevent biasing or truncation. Unless this form is accessed via a secure session (ie HTTPS or a tunnel), the password will be susceptible to being sniffed as it is being transmitted. Use the appropriate precautions. Click again to generate a totally new passphrase. The + Word or + Symbol buttons will enhance the strength of the existing passphrase. For extra security you can manually roll physical dice (two or five die rolls for each symbol or word respectively) and enter the results to add a word to your passphrase. What if I don't need a passphrase at all? I only want to generate the key and save it somewhere. Or is the solution generating a pass phrase using my generatekey, parse it to a key and then use aes encryption? – Yaron Apr 8 '14 at 8:18. Yes, it is possible to deterministically generate public/private RSA key pairs from passphrases. For even passable security, the passphrase must be processed by a key-stretching function, such as Scrypt (or the better known but less recommendable PBKDF2), and salt (at least, user id) must enter the key-stretching function; the output can then be used as the seed material for the RSA key. Weakness in Passphrase Choice in WPA Interface Anyone with knowledge of the PSK can determine any PTK in the ESS through passive sniffing of the wireless network, listening for those all-important key exchange data frames.
Especially, considering it is the equivalent of buying about 2000 BioWare points. All while getting 10X the worth in value. Mass effect 3 pc dlc. It is also much more economical. It is also quite a rip off considering the cost and the left over.Now it these add-ons in a single, separate bundle which users can buy with real money directly. Factoring in the age of these games, the prices for these DLC packs are still substantial.

xv920 join:2002-08-27 San Jose, CA | 2004-Jun-19 7:57 pm generate WEP key from passphraseI'm looking for a wep key generator that can generate a wep key from a passphrase - the same one - everytime as long as the passphrase remains the same. I tried Ben Braly's generator but it changes the key everytime despite of using the same passphrase. I just bought a laptop computer with an embedded G device for which you must enter the wep key yourself, instead of entering a passphrase and let it generate one for you. I have been successfully using a wireless network with one access point and two clients for last two years now and all devices are configured with a passphrase thus the key is automatically generated. The thing is you can not see the generated key digits anywhere. They are all masked by *. Now I have to enter these digits directly. I know the passphrase. All I need is a key generator. Thanks. | |

2004-Jun-21 1:44 am I saw it while I was searching, and tried. If you give the passphrase in the Custom WEP Key section, it only gives you back a hexadecimal representation of whatever you have just typed. For example, if you type 'abced', then it gives you '6162636465'. This is not how it works. Are you kidding? I need something that takes any-length character string as an input passphrase and then generates 13 bytes of information that you can use as a 128(104)-bit WEP key. | ||
Shootist Premium Member join:2003-02-10 Decatur, GA | 2004-Jun-21 6:14 am 2 simple facts 1. Don't use a passphrase, just make up a key, write it down, and type it in by hand. 2. There is NO embedded wireless G device, in any notebook from any manufacturer of any model. All internal wireless cards are in the MiniPCI slot and can be removed/replaced. | |
jpg366 join:2004-04-09 Humble, TX | 2004-Jun-21 9:55 pm Why don't you write a small program that will xor your passphrase with a key (you pick it and embed it in your program) and clip the highest 13 bytes from the result, and display it as hex? You're after encoding, not randomness. The commercial programs do something similar but add a pseudrandom part, probably based on the system clock value. | |
| 1 edit | 2004-Jun-22 12:27 pm I don't want to change anything in existing, working equipment. There are two wireless clients and a wireless router up and running happily for two years and I don't want to ruin that. A few days ago I bought a laptop computer with a built-in wireless interface and I just wanted to use it in my existing wireless network. For that, why would you need to do anything in any existing equipment? You would configure the new laptop the same way everybody else is working, wouldn't you? I just wanted to see this new laptop can access Internet. Two wireless venders are mixed in this network and all 3 equipments let the user enter a passphrase and then generate the WEP key from it. There should be a 'standard' way to do that. I mean, to generate a WEP key from a passphrase. I would like to write such a program myself. Can you help me? | |
Foxbat121 join:2001-04-25 Herndon, VA | 2004-Jun-22 2:44 pm Some company (I believe it is InterSil) holds the license or patent for passphrase generation. Almost all the new wireless products stop offering passphrase generation capability now to avoid paying license fee. | |

efflandt 1 editjoin:2002-01-25 Elgin, IL | 2004-Jun-22 7:02 pm Some methods generate different keys from password/passphrase than others. For example a Linux utility generates same hex key as my Linksys WAP11 v2.2 for 64(40) bit keys, but for 128(104) bit keys they differ. I think that is because Linksys generates a hex key sequence that can alternately be used for 64 or 128 bit WEP. So if you have different hardware, it is best to use actual hex keys instead of password/passphrase/ascii string. But even when I generated hex key from passphrase for Linksys WET11, it only generated the first key. I had to fill in the blanks for the other 3 alternate keys. Also sometimes the numbering of the keys varies. In Linux wlan-ng labels them 0-3 and Linksys labels them 1-4, so to use the second key would be key 1 for Linux and key 2 for Linksys. | |

sirozha join:2001-11-18 Kennesaw, GA | 2004-Sep-17 7:08 pm The WEP key you are talking about is a static key. Your access point or your other laptop doesn't generate the same new Hex key every time you connect. It is the same exact key that you initially entered. You could have entered it directly in Hex characters or as a passphrase. So, just access your router or your other laptop and copy the Hex key to your new laptop. I don't understand why you need a program that generates the same Hex key every time. If there's such a program, than it would be even easier to break your WEP key (not that it is very difficult now. It takes only about 20 min to break it). But if you use this kind of program to generate the WEP key, than one could use a dictionary attack method to guess it. | |

If you want randomness then use the random generation buttons. If you want repeatable output based on repeatable input, then you are getting exactly what you are asking for. I know it may not be easy to understand, but there is no difference in security given any function f that accepts input x and returns y (y=f(x)). If the function instead doubled the ascii value, modded 255, then displayed the hex representation you likely would never know the difference, yet it achieves the exact same thing as just returning the character itself. quote: I need something that takes any-length character stringYou got that at the link above. But, to re-iterate what someone else said - why do you want something reproducable? If this is that important the link above is indeed what you want. To be honest, though, using reproducable keys is not the best practice. Why not use a random generator to give you the correct size key then apply that key to all your devices at the same time? Then you don't need to remember the key or how it was derived. In fact it is good practice to change keys on a regular basis anyway. | |
Windows xp pro sp3 product key generator. 2004-Sep-23 8:46 am said by xv920:There are two wireless clients and a wireless quote: For that, why would you need to do anything in anyIf you've had multiple devices all using the same 128-bit key for two years (never changed) then you might as well not use encryption at all (in all honesty). If someone were interested in your network they'd have broken in long ago. The simplest method (by all means) is use a random generator to create the key you want and apply it to all the devices together. Oh - did you actually *try* to use the hex output from the link above in your device that only accepts hex? Enter the known passphrase then copy the hex. If you have multiple vendors that each accepts a passphrase and they all work together then it is very possible they are doing nothing more than this page. At worst it simply won't work and will have cost you 2 minutes time. | ||

claudeo join:2000-02-23 Redmond, WA | 2004-Sep-23 7:43 pm If you are mixing brands it is most likely that the hex key that is generated from the same passphrase will be different. I have never found two to match (but then I stopped looking pretty fast after realizing it was a waste of time). Just make up a hex key and use that. For WEP 128bit, you need 13 hex values, each of which is a pair of characters from the set 0123456789ABCDEF, or exactly 26 characters. You can even make it sort of mnemonic, but don't use something like 11223344. The hex values, or some of them, might correspond to letters or numbers, or not; it does not matter. Even better, make a list of several such keys and rotate them regularly. | |
zodiackiller @dsl.lsan03.pacbell.n | 2004-Oct-2 5:32 am Thanks. I've been searching for something like this. | |
stemeyda join:2004-01-18 Oviedo, FL | 2004-Nov-2 4:18 pm This tool ROCKS!!!! This tool will take an ascii passphrase of ANY length and generate a good 10 digit hex for 40 / 64 bit and will generate a 26 digit hex for 104 / 128 bit codes. This tool may not work on every router as the algorithm is not a standard but I have tried it now on 3 different routers and it hasn't failed me yet. If you are a traveler it is an absolute necessity to have this tool! |
