30D decryptor also works for 5D.

But where is that decryptor for 40D? I can't seem to find it (and this might also work for the EOS Mark III firmwares, they seem to have the same 288 byte header as the 40D firmware)...

Thanks! (No luck with the Mark IIIs though, so probably they changed the key again.)
