Find Graphics in TextEdit .rtfd Files

Want to find the graphics in a TextEdit document in the .rtfd format? The document is actually a package - a special kind of folder that looks like a file. To see and extract just the graphics, Control-click the document and choose Show Package Contents. A new window opens showing you just the embedded images, along with a TXT.RTF file that contains the text of the file.

 
 

WPA Weakness Discovered, but Easily Solved

Send Article to a Friend

WPA Weakness Discovered, but Easily Solved -- Following last week's article about the implementation of WPA (Wi-Fi Protected Access) in AirPort Extreme cards and base stations (see "AirPort 3.2 Update Adds New Security Options" in TidBITS-704), a security expert alerted me to a weakness in choosing keys for the WPA system. The weakness applies to the AirPort 3.2 update as well as to all other consumer WPA-enabled Wi-Fi systems. Basically, choosing a key comprised entirely of real words that are 20 characters or fewer leaves you open to that key being broken rather easily. The solution? Choose a longer key or invent 20 characters of gibberish. If you're particularly security-conscious, use the option Apple provides to enter 256 bits of encryption, which is 32 hexadecimal bytes or 64 hexadecimal digits! That's overkill, however. In last week's article, it wasn't clear why Apple even offers the hexadecimal option when other devices from Buffalo and Linksys don't; now it appears that Apple provides all of the options for entering WPA keys, where the other manufacturers don't. I've written more about this issue and posted my colleague's paper on the subject at Wi-Fi Networking News. [GF]
