PHP implements encryption and decryption method based on openssl

The example of this article describes the encryption and decryption method based on openssl in PHP. Share it with everyone for your reference, the details are as follows:

Encryption and decryption method through openssl

1. openssl encryption method:

function encrypt($id){
  $id=serialize($id);
  $key="1112121212121212121212";
  $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;
}

2. openssl decryption method:

function decrypt($encrypt)
{
  $key = '1112121212121212121212';//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;
  }
}
