請幫助。我如何製作一個加密和解密數組?DES加密和解密在PHP
<?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);
您的代碼有什麼問題?這是否工作?它不起作用嗎?你有沒有看到任何錯誤?你有什麼需要幫助的? –
