Javascript 스 크 립 트 정적 웹 페이지 암호 화 인 스 턴 스 코드 구현
이틀 전에 어떤 사람 이 정적 웹 페이지 암호 화 문 제 를 묻 는 것 을 보고 이 코드 를 썼 다.
생각:
암호 화 할 때: 먼저 사용자 의 키 A 를 md5 로 B 로 암호 화 한 다음 에 B 이상 또는 원본 파일 S10 으로 대상 파일 S1 을 얻 고 S1 을 js 변수 에 저장 합 니 다.
복호화 시: 키 를 물 어보 고 암호 화 를 조작 합 니 다.
md5 를 사 용 했 기 때문에 개인 적 으로 키 가 없 을 때 풀 수 없다 고 생각 합 니 다 (폭력 제외)
여러분 한번 써 보 세 요 하하:
원본 코드 는 다음 과 같 습 니 다:
