示例1: switch
/**
* Creates the key schedule
*
* @see Crypt_DES::_setupKey()
* @see Crypt_Base::_setupKey()
* @access private
*/
function _setupKey()
{
switch (true) {
// if $key <= 64bits we configure our internal pure-php cipher engine
// to act as regular [1]DES, not as 3DES. mcrypt.so::tripledes does the same.
case strlen($this->key) <= 8:
$this->des_rounds = 1;
break;
// otherwise, if $key > 64bits, we configure our engine to work as 3DES.
// otherwise, if $key > 64bits, we configure our engine to work as 3DES.
default:
$this->des_rounds = 3;
// (only) if 3CBC is used we have, of course, to setup the $des[0-2] keys also separately.
if ($this->mode_3cbc) {
$this->des[0]->_setupKey();
$this->des[1]->_setupKey();
$this->des[2]->_setupKey();
// because $des[0-2] will, now, do all the work we can return here
// not need unnecessary stress parent::_setupKey() with our, now unused, $key.
return;
}
}
// setup our key
parent::_setupKey();
