TLS 1.2가있는 요청에 System.Net.WebRequest
을 사용할 수 없습니다. 이렇게하면 예외 The request was aborted: Could not create SSL/TLS secure channel.
이 표시되고 프로토콜 오류 Handshake Failure
이 표시됩니다.System.Net.WebRequest 및 TLS 1.2가 haproxy를 사용하여 '핸드 셰이크 실패'를 만듭니다.
TLS 1.2를 통한 연결 및 인증은 Internet Explorer 및 Chrome에서 작동합니다. OpenSSL은 TLS 1.2를 통해이 enpoint에 연결할 수 있습니다. 비 기본을 사용하여 인증
설정
- 사용 ClientCertificates 포트 TLS 1.2을 사용하여
- 엔드 포인트는 haproxy하지만 이것은 블랙 박스
- .NET 4.7과 C# 입니다
코드 스 니펫
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
var req = WebRequest.Create($"https://{host}:{port}");
((HttpWebRequest)req).ClientCertificates = new X509Certificate2Collection(GetCertificate());
var requestStream = req.GetRequestStream();
GetCertificate()
메서드는이 소프트웨어에 포함 된 개인 키가있는 certificat를 반환합니다. 순서에서 와이어 샤크
텍스트 출력 발생 시킬수.
클라이언트 안녕하세요
