[Mcrypt-users] about the keystream...

[Kostas P. <kp...@gm...>]

Hi, I'm doing a research on cryptanalysis and I'm using libmcrypt. I
had problems compiling my c++ programs  with gcc(gcc version 3.4.4
(Gentoo 3.4.4-r1, ssp-3.4.4-1.0, pie-8.7.8) if it helps, even the ones
from the manual of the library. Anyway I use it from php without a
hinch. I would like to ask you about the keystream. I'm using cast128
and I would like to know how exactly do you convert the key from ascii
form to bitstream. You could help me with just one example eg what is
the binary representation of the key:"1234567812345678"???

Thanks in advance
