cabhPsDev802dot11SecPassPhraseToWEPKey

The Password used for PS to derive WEP encryption keys. 
After a successful set, the values of
dot11WEPDefaultKeyValue are populated as described below:
              
For wep64: 
  If cabhPsDev802dot11SecOperMode wep64 bit is set to '1'
  This object value (x) is used as a generator of a 4 octet
  seed.
              
  seed[i%4] = XOR(seed[i%4],x[i]); i from 1 to len(x) -1
              
The values of the four dot11WEPDefaultKeyValue are
calculated as indicated below : 
  loop j 1..4
  loop k 0..4
  seed = seed * (((26*8+1)*256-1)*4+1) + 2531011
  The value is always truncated at 32 bits.
  OCTETk = (seed >> 16 )& 0xFF  -lowest octet-
  end loop
  dot11WEPDefaultKeyValue(j) = OCTET0,OCTET1, ... OCTET4
  end loop
              
  Note that seed value is constantly re-computed when
  calculating each octet of each default WEP key.
              
For wep128:
  If cabhPsDev802dot11SecOperMode wep128 bit is set to '1'
  This object value (x) fills a 64 octet buffer y :
  y = x,x,x...up to 64 octets.
  Calculate the 128-bit MD5 digest of y
  the values of all dot11WEPDefaultKeyValue (1..4)
  are calculated by truncating the first first 13 octets
  of MD5y.
              
dot11WEPDefaultKeyValue = MD5y0,MD5y1, .. MD5y12 
              
  This object value is normally read by issuing SNMP
  request PDUs. This object can be cleared with an SNMP
  SET to an empty string Value and the PS MUST not update
  the type of keys being set to '1' in
  cabhPsDev802dot11SecOperMode.
              
If cabhPsDev802dot11SecUsePassPhraseToKeyAlg is set to 
false(2), the behavior of a SET to this object depends 
on the bits set for cabhPsDev802dot11SecOperMode as 
follows:
              
              
  If cabhPsDev802dot11SecOperMode bit wep64 is set to '1'
  and this object value length is 5 octets, the MIB object
  dot11WEPDefaultKeyValue.1 (WEP key 0) is populated with
  this object value, otherwise an error 'inconsistentValue'
  is reported.
              
  If cabhPsDev802dot11SecOperMode bit wep128 is set to '1'
  and this object value length is 13 octets, the MIB object
  dot11WEPDefaultKeyValue.1 (WEP key 0) is populated with
  this object value, otherwise an error 'inconsistentValue'
  is reported.
              
Vector examples for wep64 and wep128 key derivation:
              
  Note:
  % refers to the module operation (reminder of the
  quotient of i and 4); XOR is the OR exclusive boolean
  operation.
