## JWTトークンの取り扱い

インストールした複数のモジュールをインポートします。

JWTトークンの署名に使用されるランダムな秘密鍵を生成します。

安全なランダム秘密鍵を生成するには、次のコマンドを使用します：

	// Verify if we can employ autotune without running out of capacity,
	// if we do run out of capacity, make sure to turn-off autotuning
	// in such situations.
	if autotune {
		newConcurrent := concurrent + (concurrent+1)/2
		autoTunedCapacityNeeded := uint64(newConcurrent * size)
		if capacity < autoTunedCapacityNeeded {
			// Turn-off auto-tuning if next possible concurrency would reach beyond disk capacity.
			return true, false, ""

        }
      }
    }
  }

    why we're doing this and how to upgrade.

    The OkHttp 3.12.x branch will be our long-term branch for Android 2.3+ (API level 9+) and Java
    7+. These platforms lack support for TLS 1.2 and should not be used. But because upgrading is
    difficult we will backport critical fixes to the 3.12.x branch through December 31, 2021. (This
    commitment was originally through December 31, 2020; we have since extended it.)
