PHP使用openssl扩展实现加解密方法示例

<?php

class DesUtil
{
  /
    Des 加密
   
    @param $str
    @param $secretKey
    @param string $iv
    @return string
   /
  public static function encrypt($str, $secretKey, $iv = '')
  {
    return base64_encode(openssl_encrypt($str, 'des-cbc', $secretKey, OPENSSL_RAW_DATA, $iv));
  }

  /
    Des 解密
   
    @param $str
    @param $secretKey
    @param string $iv
    @return string
   /
  public static function decrypt($str, $secretKey, $iv = '')
  {
    return openssl_decrypt(base64_decode($str), 'des-cbc', $secretKey, OPENSSL_RAW_DATA, $iv);
  }
}
