TLS-handshake with own random numbers in Java

由 ぐ巨炮叔叔 提交于 2019-12-13 18:28:49
问题 I have a a piece of hardware which realises some crypto functions like random number generation (e.g a SmartCard). I would like to use this hardware during my TLS hadshake. Is it possible to do this, without implementing the TLS-Handshake by my own? I tried to extend the class "SecureRandom" but the "next" methode is final so I can't override it so that it will return 'my' genetrated numbers. So basically I would like to "outsource" all the crypto functions without implementing the TLS

SSLException during handshake while resuming cached session [duplicate]

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: SSL handshake alert: unrecognized_name error since upgrade to Java 1.7.0 My J2SE app uses HttpsUrlConnection to access a secure location. It used to work just fine until I updated my JRE to 1.7. Now I get the "Remote host closed connection during handshake" SSLException. After running the app using -Djavax.net.debug=ssl:handshake, both under JRE 1.6 and JRE 1.7, my impression is that under 1.7 the cached client

How to detect Shake Gesture while application in Background?

问题 I'm currently working on a music player app, and like the iPod application, I would like to shuffle songs with shake gesture. I'm implementing motion methods like Apple recommends to, and in foreground everything works fine. - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event; - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event; - (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event; But I just can't figure out how to call those methods

OpenSSL server on OpenWRT router fails handshakes after time and requires a reboot to work again

由 ≡放荡痞女 提交于 2019-12-11 04:27:55
问题 Okay, I admit this is the weirdest openssl question I have ever seen - but what could be causing a problem that only a REBOOT fixes for OpenSSL? The basics are that we have a MITM style SSL proxy on an OpenWRT router. The code works great for hours, and then for some unknown reason (nothing in dmesg or logread) we start getting client handshake failures where openssl just hangs on SSL_ERROR_WANT_READ . We do use edge triggered epoll but as I said, the code works for HOURS without issue. Then

TCP four-way handshake

由 好久不见. 提交于 2019-12-11 01:26:54
问题 Four-way handshake connection termination can be reduced to three-way and even two way one. Is it possible the three-way handshake connection establishment would be extended to four-way? SYN=> <=ACK <=SYN ACK=> 回答1: Given the semantics of SYN and ACK it should be possible to send SYN+ACK in different packets and those delay the handshake. E.g. client sends a SYN, server replies with an ACK to acknowledge the wish of the client for a new connection, but it does not grant the wish yet. Later

Handshake alert: unrecognized_name error

由 安稳与你 提交于 2019-12-09 05:37:36
问题 I am using Charles 3.7 to debug SSL connections. I was able to view most of the HTTPS connections, however there is 1 or 2 sites that returned "SSLProtocol: handshake alert: unrecognized_name" when I try to debug it, and I was unable to load the website with Charles on. I am able to do so using Fiddler. Any ideas on how to resolve this issue? Thanks. 回答1: I came across this when using the latest beta Charles 3.10b9 on 10.10. We fixed by using a similar method to Shade's answer: I opened info

Why do I get a handshake failure (Java SSL)

由 谁说我不能喝 提交于 2019-12-09 05:27:55
问题 I'm connecting to a web service over HTTPS. I've done all that I think is required to make it work, but in the end I get a handshake failure. I found out that as a new user I can't post more than 2 links due to "spam protection" - thanx a lot stackoverflow...anyway here's a link to a pastebin post with all the links spelled out...so when I write "link#1" here it's a reference to these links: http://pastebin.com/y4zGNRC7 I verified the same behavior using HttpClient (GET on the service URL)

Openssl Handshake failures after thousands of successful connections

由 我与影子孤独终老i 提交于 2019-12-08 18:49:32
I'm having a problem where my server stops accepting connections sometimes after thousands of successful connections. I create a global SSL_CTX once, and then an SSL object for every connection, which I dispose every time. I'm using version 1.0.2h. Once the problem occurs, the only way to get around it is to restart the server, basically recreating the context. As far as I can tell, the context "looks" fine, and the so does the session object. I have watched the network traffic using wireshark, and every packet looks fine until the handshake fails. Does anyone have any suggestions on how to
