WiFi WPA Pre-Shared Key standard

Please can you provide a pointer to an authorative definition of the
standard for the content of a WPA PSK string?

Certainly, www.google.com .

Yes, I can. However, I'm not sure I want to do so. Is there a
problem with using Google *FIRST* and then asking if you don't find
something? I assume you're trying to crack WPA.

Start here:

Nope.

I'm trying to understand why certain WPA keys don't work between a
particular router and WiFi card combination. I'm looking for the
definitive stuff that *should* have guided manufacturers and O/S and
driver coders into producing a common standard.

Doesn't quite do the biz, does it?

If you have anything useful to contribute, please cough up
otherwise...

You're welcome.

WPA was inscribed by the Wi-Fi Alliance and is a subset of IEEE
802.11i. The 802.11i standard is at:
http://standards.ieee.org/getieee802...2.11i-2004.pdf
You may also need some of these others to decode the references to
802.11b/g.
http://standards.ieee.org/getieee802/802.11.html

You might also want to check if your router and card have been tested
and certified for WPA and/or WPA2 compliance.

This might explain some of your compatibility issues if you're using
some of the new authentication modes in WPA2:

If your card is running on a Windoze XP platform, you might wanna
enable WZC debugging and see what it complains about:

Jeff,

Thanks for responding to my rantin' in good spirit. And thanks for
the pointers that look both authoritative and impenetrable for my
purposes :-) I've done my bit trying to decode IEEE, ISO and ECMA
standard yonks ago.

Let metry asking again from the sharp-end:
I'm configuing a wireless network.
I create a text file on a flash disk drive.
I ripple my fingers across the keyboard to generate a random PSK
string.
I copy that string to the setup screen for the wireless router do
the required accept/restart ritual.

Cient PC spots the new network and I ask to connect.
- copy the PSK string from the flash drive file and paste it
twice as requested
- client PC uummms and aaars but cannot connect

Subsequent deduction reveals that one particular character f*cks it
up. So what are the allowed values?

Good spirits? Directing you to the IEEE 802.11[a-z] specs is favored
method of retaliation.

I guess I have to read 802.11i. That usually turns my brain to mush,
but that's already the case after preparing my income taxes.

H.4 Suggested pass-phrase-to-PSK mapping (Page 166), proclaims:

- A pass-phrase is a sequence of between 8 and 63 ASCII-encoded
characters. The limit of 63 comes from the desire to distinguish
between a pass-phrase and a PSK displayed as 64 hexadecimal
characters.

- Each character in the pass-phrase must have an encoding in
the range of 32 to 126 (decimal), inclusive.

So, there you have it. Stay between ASCII codes 32 and 126 and you're
safe. Here's a handy table:
| http://www.asciitable.com
I guess backspace, bell characters, control characters, and graphic
symbols are not acceptable.


Incidentally, here's the rules for the SSID. See:
| http://www.cisco.com/warp/public/779...t-security.htm
Note: In this text field, the following six characters are not
allowed: ?, ", $, [, \, ], and +. In addition, the following three
characters cannot be the first character: !, #, and ;.
