### Tipos simples

Você pode declarar todos os tipos padrão de Python, não apenas `str`.

Você pode usar, por exemplo:

* `int`
* `float`
* `bool`
* `bytes`

```Python hl_lines="1"
{!../../docs_src/python_types/tutorial005.py!}
```

### Tipos genéricos com parâmetros de tipo

import jcifs.smb1.UniAddress;
import jcifs.smb1.util.Hexdump;

public final class NtlmChallenge implements Serializable {

    public byte[] challenge;
    public UniAddress dc;

    NtlmChallenge( byte[] challenge, UniAddress dc ) {
        this.challenge = challenge;
        this.dc = dc;
    }

    public String toString() {
        return "NtlmChallenge[challenge=0x" +

## Passwort-Hashing

„Hashing“ bedeutet: Konvertieren eines Inhalts (in diesem Fall eines Passworts) in eine Folge von Bytes (ein schlichter String), die wie Kauderwelsch aussieht.

Immer wenn Sie genau den gleichen Inhalt (genau das gleiche Passwort) übergeben, erhalten Sie genau den gleichen Kauderwelsch.

### সিম্পল টাইপ

আপনি `str` ছাড়াও সমস্ত স্ট্যান্ডার্ড পাইথন টাইপ ঘোষণা করতে পারেন।

উদাহরণস্বরূপ, আপনি এগুলো  ব্যবহার করতে পারেন:

* `int`
* `float`
* `bool`
* `bytes`
