## Gesamtübersicht

Sehen wir uns zunächst kurz die Teile an, die sich gegenüber den Beispielen im Haupt-**Tutorial – Benutzerhandbuch** für [OAuth2 mit Password (und Hashing), Bearer mit JWT-Tokens](../../tutorial/security/oauth2-jwt.md){.internal-link target=_blank} ändern. Diesmal verwenden wir OAuth2-Scopes:

  public static final MediaType ANY_APPLICATION_TYPE = createConstant(APPLICATION_TYPE, WILDCARD);

  public static final MediaType ANY_FONT_TYPE = createConstant(FONT_TYPE, WILDCARD);

  /* text types */

/// tip

The IP `0.0.0.0` is commonly used to mean that the program listens on all the IPs available in that machine/server.

///

The docs UI would also need the OpenAPI schema to declare that this API `server` is located at `/api/v1` (behind the proxy). For example:

```JSON hl_lines="4-8"
{
    "openapi": "3.1.0",

## 패스워드 해싱

"해싱(Hashing)"은 어떤 내용(여기서는 패스워드)을 해석할 수 없는 일련의 바이트 집합(단순 문자열)으로 변환하는 것을 의미합니다.

동일한 내용(똑같은 패스워드)을 해싱하면 동일한 문자열을 얻습니다.

하지만 그 문자열을 다시 패스워드로 되돌릴 수는 없습니다.

### 패스워드를 해싱하는 이유

데이터베이스를 탈취당하더라도, 침입자는 사용자의 평문 패스워드 대신 해시 값만 얻을 수 있습니다.
