"다른 무언가를 기다리는 것"은 일반적으로 비교적 "느린" (프로세서와 RAM 메모리 속도에 비해) <abbr title="Input and Output">I/O</abbr> 작업을 의미합니다. 예를 들면 다음의 것들을 기다리는 것입니다:

* 네트워크를 통해 클라이언트로부터 전송되는 데이터
* 네트워크를 통해 클라이언트가 수신할, 당신의 프로그램으로부터 전송되는 데이터
* 시스템이 읽고 프로그램에 전달할 디스크 내의 파일 내용
* 당신의 프로그램이 시스템에 전달하는, 디스크에 작성될 내용
* 원격 API 작업
* 완료될 데이터베이스 작업
* 결과를 반환하는 데이터베이스 쿼리
* 기타

수행 시간의 대부분이 <abbr title="Input and Output">I/O</abbr> 작업을 기다리는데에 소요되기 때문에, "I/O에 묶인" 작업이라고 불립니다.

And copy the output to the variable `SECRET_KEY` (don't use the one in the example).

Create a variable `ALGORITHM` with the algorithm used to sign the JWT token and set it to `"HS256"`.

Create a variable for the expiration of the token.

In case of a S3 multi-part operation each part is en/decrypted with the scheme shown in Figure 1. However, for each part a unique secret key is derived from the OEK and the part number using a PRF. So in case of multi-part not the OEK but the output of `PRF(OEK, part_id)` is used as secret key.
