Question

请帮忙。如何在加密和解密中创建数组？

<?php
    class DES{

        function encrypt($plainText, $cipherKey){
            //plainText
            $result = $this->toBiner($plainText);
            $result = $this->InitialPermutation($result);
            //key
            $key = $this->toBiner($cipherKey);
            $key = $this->kompresBit($key);
            $arrLeftShift = $this->LeftShift($key);
            //final
            $result = $this->keyExpansion($result, $arrLeftShift);
            return $result;
        }

        function decrypt($encryptedText, $cipherKey){
            $key = $this->toBiner($cipherKey);
            $key = $this->kompresBit($key);
            $arrLeftShift = $this->LeftShift($key);

            $result = $this->reverseKeyExpansion($encryptedText, $arrLeftShift);
            $result = $this->revInitialPermutation($result);

我对加密知之甚少，但根据我的理解，DES不是推荐的加密标准：http://en.wikipedia.org/wiki/Data_Encryption_Standard
