php实现基于openssl的加密解密方法
<?php
class openssl{
private $key = ‘key‘;
public $id = ‘‘;
function encrypt($id){
$id=serialize($id);
$this->id = $id;
$key= $this->key;
$data[‘iv‘]=base64_encode(substr(‘fdakinel;injajdji‘,0,16));
$data[‘value‘]=openssl_encrypt($id, ‘AES-256-CBC‘,$key,0,base64_decode($data[‘iv‘]));
$encrypt=base64_encode(json_encode($data));
return $encrypt;
}
function decrypt($encrypt){
$key = $this->key;//解密钥匙
$encrypt = json_decode(base64_decode($encrypt), true);
$iv = base64_decode($encrypt[‘iv‘]);
$decrypt = openssl_decrypt($encrypt[‘value‘], ‘AES-256-CBC‘, $key, 0, $iv);
$id = unserialize($decrypt);
if($id){
return $id;
}else{
return 0;
}
}
}
$obj = new openssl();
$encrypt = $obj->encrypt(‘1‘);
echo $obj->decrypt($encrypt);
