컴퓨터나 스마트폰과 같은 디지털 장비로부터 범죄와 관련된 디지털 정보를 발견하거나 복구해내는 디지털 포렌식 기술은 컴퓨터 공학 기술뿐만 아니라 암호학과 같은 다양한 자연과학적 분야들이 적용되는 분야이다. 특히, 용의자가 암호화한 파일을 복호화하거나, 암호화에 사용한 패스워드를 발견해내는 기술은 수사에 결정적인 역할을 하는 경우가 빈번하여, 포렌식 수사관들의 의존도가 높은 기술분야로 인식되고 있다. 대부분은 직접적인 복호화보다 패스워드를 유추하거나 발견해내는 기술들이 주를 이루고 있다. 본 논문에서는 이러한 패스워드 검사작업을 위한 다양한 기능들을 소개하고 이를 웹기반의 분산처리 방식을 통해 고속으로 수행할 수 있는 시스템의 설계 내용에 대해 기술한다.
