    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.)

## 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：

  float result_data[4] = {0};
  memcpy(&result_data[0], TF_TensorData(result_tensor),
         TF_TensorByteSize(result_tensor));

  // Build expected result & verify.
  float e_vals[] = {6.0f, 8.0f, 10.0f, 12.0f};

  int data_len = 4;  // length of e_vals
  for (int i = 0; i < data_len; i++) {
    EXPECT_EQ(result_data[i], e_vals[i]);
  }

  TF_DeleteTensor(result_tensor);
  TF_DeleteAbstractTensor(result);

  // capacity is the value reported by the CSI driver in its GetCapacityResponse
  // for a GetCapacityRequest with topology and parameters that match the
  // previous fields.
  //
  // The semantic is currently (CSI spec 1.2) defined as:
  // The available capacity, in bytes, of the storage that can be used
  // to provision volumes. If not set, that information is currently
  // unavailable.
  //
  // +optional

    if (bytes != null && bytes.length == 16) {
      for (int i = 0; i < 10; i++) {
        if (bytes[i] != 0) {
          return false;
        }
      }
      for (int i = 10; i < 12; i++) {
        if (bytes[i] != (byte) 0xff) {
          return false;
        }
      }
      return true;
    }
    return false;
  }
