설명

클래스는 RSAKeyValue<RSAKeyValue> XML 디지털 서명 사양에 의해 정의 된 XML 서명의 요소를 나타냅니다. 요소는 <RSAKeyValue> 공개 키를 설명하는 요소(클래스로 KeyInfo 표시됨)의 <KeyInfo> 하위 요소입니다RSA. <RSAKeyValue> 요소에는 문서에 디지털 서명하는 데 사용되는 프라이빗 키에 해당하는 공개 키가 포함되어 있습니다. 문서의 받는 사람이 공개 키를 사용하여 XML 서명의 유효성을 검사합니다.

XML 디지털 서명에 RSAKeyValue 공개 키를 추가하려는 경우 클래스를 사용합니다.

키가 생성자에 명시적으로 제공되지 않으면 새 RSA 키 쌍이 임의로 생성됩니다.

요소에 <RSAKeyValue> 대한 자세한 내용은 W3C 사양을 참조하세요.

생성자

RSAKeyValue()

무작위로 생성된 새로운 RSAKeyValue 공개 키를 사용하여 RSA 클래스의 새 인스턴스를 초기화합니다.

RSAKeyValue(RSA)

지정된 RSAKeyValue 공개 키를 사용하여 RSA 클래스의 새 인스턴스를 초기화합니다.

속성

Key

공개 키를 보유하는 RSA의 인스턴스를 가져오거나 설정합니다.

메서드

Equals(Object)

지정된 개체가 현재 개체와 같은지 확인합니다.

(다음에서 상속됨 Object)
GetHashCode()

기본 해시 함수로 작동합니다.

(다음에서 상속됨 Object)
GetType()

현재 인스턴스의 Type을 가져옵니다.

(다음에서 상속됨 Object)
GetXml()

RSA 키 절의 XML 표현을 반환합니다.

LoadXml(XmlElement)

XML 요소에서 RSA 키 절을 로드합니다.

MemberwiseClone()

현재 Object의 단순 복사본을 만듭니다.

(다음에서 상속됨 Object)
ToString()

현재 개체를 나타내는 문자열을 반환합니다.
