## Gerenciadores de contexto

### O que são gerenciadores de contexto

"Gerenciadores de Contexto" são qualquer um dos objetos Python que podem ser utilizados com a declaração `with`.

			w.Reset()
			buf := NewWriterSize(w, bs)
			context := fmt.Sprintf("nwrite=%d bufsize=%d", nwrite, bs)
			n, e1 := buf.Write(data[0:nwrite])

				t.Errorf("%s: buf.Write %d = %d, %v", context, nwrite, n, e1)
				continue
			}
			if e := buf.Flush(); e != nil {
				t.Errorf("%s: buf.Flush = %v", context, e)
			}

			written := w.Bytes()
			if len(written) != nwrite {

## パスワードのハッシュ化と検証

必要なツールを `passlib`からインポートします。

PassLib の「context」を作成します。これは、パスワードのハッシュ化と検証に使用されるものです。

/// tip | "豆知識"

PassLibのcontextには、検証だけが許された非推奨の古いハッシュアルゴリズムを含む、様々なハッシュアルゴリズムを使用した検証機能もあります。

例えば、この機能を使用して、別のシステム（Djangoなど）によって生成されたパスワードを読み取って検証し、Bcryptなどの別のアルゴリズムを使用して新しいパスワードをハッシュするといったことができます。
