AES 256 암호화가 결과와 일치하지 않습니다.

Encrypted string에 말하는 문서가 using AES256있습니다. 두 가지 값을 가진 내 문서에 따르면 10002:1486703720424 AND HashKey: hpIw4SgN)TxJdoQj=GKo)p83$uHePgoF결과가 생성 1ltQFLRGNif73uCNzi0YEvBqLKiRgx6fWsk5e/GcTQc=되지만 결과 를 생성하려고 할 때 6SKbqJAxbBrg4eU7r/B8gJoJEPg+KjMvGL5L7bfykUU=내 코드에서 생성 됩니다. 내가 뭘 잘못하고 있는지 말씀해 주시겠습니까? 암호화를하는 것은 이번이 처음이므로 실수를 찾기 위해 약간 혼란 스럽습니다.
