JCA가 JCE를 대신하는 것이 간단하다고 생각했습니다. 그러나 내 시스템에 모든 공급자를 확보하기위한 테스트 코드 작성은 그렇지 않습니다. JCA와 공급자의 관계는 JCE입니까?
나는 다음과 같은주의 :- 일부 알고리즘은 여러 공급자가 :
- JCA는 JCE 에 무엇이 넘어 알고리즘의
type가있는 것 (예를 들면
MD5withRSA는
SunRsaSign에뿐만 아니라
SunJSSE)
항목 1은 JCE 공급자가 제공하는 라이브러리/배열로 JCA가 표시되는 것처럼 의미가 있습니다.
항목 2는 JCA가 "동일한"JCE 공급자의 배열과 정확히 일치하지 않기 때문에 조금 혼란 스럽습니다. 그것은 모든 종류의 공급자, JCE 인터페이스 또는 연결되지 않는 모든 종류의 물 공급 구멍입니다.
그래서 은 JCA, 제공자 및 JCE 간의 작업 관계는 무엇입니까? 공급자는 독립적 인 사일로에도 존재합니까? 아니면 서로를 "구축"합니까? 코드에 관심이 사람이 질문을하라는 메시지가 결과에 대한
