      temp_dir should not be used for security operations. From the docs:
      'The temporary directory may be shared among users, or between processes
      with different privileges; thus, the creation of any files or directories
      in the temporary directory must use a secure method to create a uniquely
      named file. Creating a file or directory with a fixed or predictable name
      may result in “insecure temporary file” security vulnerabilities.'
