This seems like a basic programming issue, not a Mac networking issue, but I'll bite...

The code you posted appears to take a UTF-8 C string, convert it to a CFString, convert the CFString to ASCII, and then store the ASCII text in a CFData object. The net result would be the same bytes you started with.

Are you just asking how one might convert a hex string to a number? I would think strtol() would do that quite handily.

Please Help me,

How can I convert  a HEX WEP  a CFString to CFData ???

example::

 CFStringRef WepKey = CFSTR("AAFCE8A294"); //as HEX -> AAFCE8A294

 void*   keys[1];
 void*   values[1];
 UInt8 Buffer[21];
 memset(Buffer,0,sizeof(Buffer));

WepKey = CFStringCreateWithCString(kCFAllocatorDefault, cWepKey, kCFStringEncodingUTF8);
CFRange range = CFRangeMake(0, CFStringGetLength(WepKey));
CFIndex usedBufLen = 0;
CFIndex iBytes = CFStringGetBytes( WepKey, range, kCFStringEncodingASCII, 0 , false, Buffer, CFStringGetLength (WepKey), &usedBufLen );


CFDataRef Password = CFDataCreate(kCFAllocatorDefault, Buffer, iBytes);

 keys[0] = (void*) CFSTR("WEPKEY");;
 values[0]  = (void*) Password;

 .......



Result:
   "WEPKEY" CFDATA  <41414643 45384132 3934>


this is the Rigth encoded Result: "WEPKEY" CFDATA <abdacee5 0544abd8 cee1053a abdace96 053babaf>

PLEASEEEEEE HELP MEEEEEEEEEEEEEE ! ! !
