You get a handshake_failure error when trying to talk to a server running with this. When you build a deployable jre,

问题 I'm writing a client for iOS to connect to my server by SSL/TLS. I have decided to use NSStream implementation. And now my project has been stopped due to SSL Handshake, I don't know how handle it with streams and can't find any examples of delegates with it. As I understood the certificate passing should be in NSStreamEventHasSpaceAvailable, but actually I don't understand how. I need to pass my certificate (he is not installed on device). Can someone help me? This code crashes with this:

问题 I have a netty client that waits awaitUninterruptibly for the server to send something. This seems to work fine in the version 3.7.

问题 I'm connecting to MSSQL database through my ASP .NET application, but sometimes I got this error while opening connection. Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement. This could be because the pre-login handshake failed or the server was unable to respond back in time.

问题 I know this subject is discussed in many places, but after I went through almost all of them, I have decided to create my first StackOverflow question... The problem is the following: I want to connect to a secured webservice (https) that use a certificate to restrict the access, and a username/password to authenticate the user. So i have a client cert (p12 file) and a server cert (pem or der file). I try to use the HttpURLConnection class, because from what I've heard, Apache library will no

问题 I have an application embedding Jetty. I would like to use client cert authentication in SSL and when I enable that; I am getting the following exception at start of request. But the request is getting served properly after that. This exception comes only when accessed from IE or Chrome. It does not come when accessed from Firefox.
