阅读更多关于 Yet another Paypal Curl / SSL v3 Handshake Error - SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure

问题 I know there are a number of people asking this question, but none of the solutions I've read to date have worked for me. A site with a Paypal IPN listener fails in the curl postback.

问题 I'm attempting to disable SSLv3 in Apache which I've installed on Windows via xampp. But I'm having trouble figuring out how.

阅读更多关于 How to disable SSLv3 in android for HttpsUrlConnection?

问题 We wrote client application in android which connects with https servers using HttpsUrlConnection apis. Due to Poodle vulnerability, we need to disable SSLv3 from the list of enabled protocols while invoking any request. We followed the guidelines captured by oracle and added following line before invoking url connection java.lang.System.setProperty("https.protocols", "TLSv1"); This solution works fine with normal java program.

What version of SSL/TLS does System.Web.Services.Protocols.SoapHttpClientProtocol use?

阅读更多关于 What version of SSL/TLS does System.Web.Services.Protocols.SoapHttpClientProtocol use?

Now that SSL 3 has been found to be vulnerable to the POODLE attack: What version of SSL/TLS does System.Web.Services.Protocols.SoapHttpClientProtocol use when connecting to any https Uri? I use SoapHttpClientProtocol to connect to several 3rd party SOAP API's. One of these has now said they will block any request that uses SSL 3. But SoapHttpClientProtocol is part of the .Net core framework (using 4.5) so it is not obvious what version of SSL it uses, or how to override the version. Note this question is not a duplicate of Which versions of SSL/TLS does System.Net.WebRequest support? . I use
