TLS 1.2 not negotiated in .NET 4.7 without explicit ServicePointManager.SecurityProtocol call

问题 I need to upgrade a .NET application to support a call to an API on a website that only supports TLS 1.2. From what I read, if the application is targeting 4.6 or higher then it will use TLS 1.2 by default. To test I created a Windows Forms app that targets 4.7. Unfortunately it errors when I don't explicitly set ServicePointManager.SecurityProtocol. Here is the code: HttpClient _client = new HttpClient(); var msg = new StringBuilder(); // If I uncomment the next line it works, but fails even

问题 I am trying to connect to a web service that only supports TLS 1.2. I'm having trouble with the syntax for setting option9 ( WinHttpRequestOption_SecureProtocols ) to use TLS 1.2 I've tried EXEC sp_OASetProperty @objectID, 'Option', '2720', 9 but no dice. 回答1: Not because it's a good idea, but so that no one else has to figure out how to use the horrid sp_OAxxx stored procedures... Here's an update to my ancient HTTP stored procedure to use both WinHttp and set that option. The Option

Iam having this strange issue in which the retrofit keeps throwing me "SSL handshake aborted: ssl=0x618d9c18: I/O error during system call, Connection reset by peer" in kitkat, whereas the same code working fine in lollipop devices. Iam using an OkHttpClient client like the following public OkHttpClient getUnsafeOkHttpClient() { try { final TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() { @Override public void checkClientTrusted( java.security.cert.X509Certificate[] chain, String authType) { } @Override public void checkServerTrusted( java.security.cert

问题 I am using com.loopj.android:android-async-http:1.4.9 for my request to server. It was working fine until I SSL/TLS is required in my server. So I need to modify my AsyncHTTPClient to use HTTPS in all URLs. I checked this similar how to make HTTPS calls using AsyncHttpClient? but did not provide clear solution to the problem. The accepted solution was not secure as well because of this warning from the library itself: Warning! This omits SSL certificate validation on every device, use with

问题 I support a .NET site which (amongst many, MANY, other things) talks to remote APIs from supplier systems. We want to upgrade to support TLS 1.2 We're hoping to do so as per this question: Are there .NET implementation of TLS 1.2? But how do I check that this is actually working once I've made the change. Ideally one of my supplier sites would start using TLS 1.2 ONLY and then my test could just be "can we talk to that supplier now?" But we don't have that. I'm guessing I can do something

问题 For supporting HTTPS connections through a Java 1.6 API to remote hosts using TLS 1.2, we have developed a customized TLS SocketConnection factory based on Bouncy Castle Libraries (v. 1.53) It's very easy to use, just: String httpsURL = xxxxxxxxxx URL myurl = new URL(httpsURL); HttpsURLConnection con = (HttpsURLConnection )myurl.openConnection(); con.setSSLSocketFactory(new TSLSocketConnectionFactory()); InputStream ins = con.getInputStream(); During testing, I connect different web and
