단방향 해시 함수는 수학적인 연산을 통해 원본 메시지를 변환하여 암호화된 메시지인 다이제스트를 생성 동일한 메시지가 언제나 동일한 다이제스트를 갖는다면, 공격자가 전처리(pre-computing)된 다이제스트를 가능한 한 많이 확보한 다음 이를 탈취한 다이제스트와 비교해 원본 메시지를 찾아내거나 동일한 효과의 메시지를 찾을 수 있다 해시 함수는 암호학에서 널리 사용되지만 원래 패스워드를 저장하기 위해서 설계된 것이 아니라 짧은 시간에 데이터를 검색하기 위해 설계된 것 해시 함수의 빠른 처리 속도로 인해 공격자는 매우 빠른 속도로 임의의 문자열의 다이제스트와 해킹할 대상의 다이제스트를 비교할 수 있다 MD5를 사용한 경우 일반적인 장비를 이용하여 1초당 56억 개의 다이제스트를 대입 반면 사용자는 웹 사이트에서 패스워드를 인증하는 데 걸리는 시간에는 그리 민감하지 않다 즉, 해시 함수의 빠른 처리 속도는 사용자들보다 공격자들에게 더 큰 편의성을 제공 이를 Salting을 통해 보완한다 > [NAVER D2](https://d2.naver.com/helloworld/318732)

SHA-1은 이전에 널리 사용되던 MD5를 대신해서 쓰이기도 한다. 혹자는 좀 더 중요한 기술에는 SHA-256이나 그 이상의 알고리즘을 사용할 것을 권장한다. 256비트로 구성되어 64자리 문자열을 반환한 값 ### Hash windows file ```type(Get-FileHash -Algorithm SHA256 -Path {path}).Hash |Out-File -FilePath {output}```
