Bouncy Castle 1.47 API를 사용하여 DSA/El Gamal PGP 키 링을 생성하는 작은 프로그램을 만들었습니다. 키 생성은 오류없이 실제로 실행됩니다.GPG에서 오류없이 가져 오는 탄력성있는 dsa/elgamal 키 쌍 생성

후 나는 그것을 알려줍니다 확인을 클릭합니다 : 나는 다음과 같은 오류가 나는 장갑 출력을 사용하여 파일에 개인 및 공개 키를 내보내고 내가 GPG에 생성 된 개인 키를 가져올 때 (KGpg를 정확한 수) 나만 하나의 키만 처리되었다. 화면에 1024/0로 표시되므로 DSA 키만 사용 된 것처럼 보입니다.
** 편집 ** 난 그냥 Windows에서 PGP 10.1.0에서 키를 열리는 시도하고 또한 나에게 에 오류가 있습니다 "키 링이 나쁜 (손상) PGP 패킷을 포함합니다."
아래 코드는 Utility 클래스이고, 두 번째는 키를 생성하는 프로그램입니다.

생성 된 출력은 2 개 파일 "secret.asc"와 "public.asc"나는 GPG에 "secret.asc"를 가져 오려고하면 있습니다 내가 얻을 오류 및 엘 가말 서브 키 수입되지 않습니다.
누구에게이 문제가있을 수 있다는 것을 알고 있습니까?
