Not exactly. WEP does come in two flavours, with the underlying
encryption mechanism being 64-bit RC4 and 128-bit RC4 respectively.
However in each case 24 bits of the RC4 key are used for the IV.
Hence the actual settable WEP key is only 40 bits and 104 bits
respectively. In Linux these can be set either as a hex number of the
appropriate size, or as a string of length 5 or 13 respectively.

Of course card vendors still market it as 128 bit WEP.
